GENERAL DESCRIPTION
INPUT/OUTPUT CONNECTIONS
The ADS-916 is a high-performance, 14-bit, 500kHz sampling A/D converter. This device samples input signals up to Nyquist frequencies with no missing codes. The ADS-916 features outstanding dynamic performance including a THD of –90dB. Housed in a small 24-pin DDIP or SMT (gull-wing) package, the functionally complete ADS-916 contains a fast-settling sample-hold amplifier, a subranging (two-pass) A/D converter, a precise voltage reference, timing/control logic, and errorcorrection circuitry. Digital input and output levels are TTL. Requiring ±15V (or ±12V) and +5V supplies, the ADS-916 dissipates 1.8W (1.6W for ±12V) maximum. The unit is offered with a unipolar input (0 to +10V). Models are available for use in either commercial (0 to +70°C) or military (–55 to +125°C) operating temperature ranges. Applications include radar, sonar, spectrum analysis, and graphic/medical imaging.

Footnotes: ➀ All power supplies must be on before applying a start convert pulse. All supplies and the clock (START CONVERT) must be present during warmup periods. The device must be continuously converting during this time. There is a slight degradation in performance when using ±12V supplies.

➁ See Ordering Information for availability of ±5V input range. Contact DATEL for availability of other input voltage ranges.
➄ This is the time required before the A/D output data is valid after the analog input is back within the specified range.
➂ A 500 kHz clock with a 200ns wide start convert pulse is used for all production testing. Only the rising edge of the start convert pulse is required for the device to operate (edge-triggered). See Timing Diagram for more details.
TECHNICAL NOTES initial offset and gain errors can be reduced to zero using the input circuit of Figure 2. When using this circuit, or any similar offset and gain-calibration hardware, make adjustments following warmup. To avoid interaction, always adjust offset before gain.
1. Obtaining fully specified performance from the ADS-916 requires careful attention to pc-card layout and power supply decoupling. The device's analog and digital ground systems are connected to each other internally. For optimal performance, tie all ground pins (14, 19 and 23) directly to a large analog ground plane beneath the package.
3. When operating the ADS-916 from ±12V supplies, do not drive external circuitry with the REFERENCE OUTPUT. The reference's accuracy and drift specifications may not be met, and loading the circuit may cause accuracy errors within the converter.
Bypass all power supplies and the REFERENCE OUTPUT (pin 21) to ground with 4.7µF tantalum capacitors in parallel with 0.1µF ceramic capacitors. Locate the bypass capacitors as close to the unit as possible. If the user-installed offset and gain adjusting circuit shown in Figure 2 is used, also locate it as close to the ADS-916 as possible.
4. Applying a start convert pulse while a conversion is in progress (EOC = logic "1") initiates a new and inaccurate conversion cycle. Data for the interrupted and subsequent conversions will be invalid.
2. The ADS-916 achieves its specified accuracies without the need for external calibration. If required, the device's small 3

ADS-916 CALIBRATION PROCEDURE
Zero/Offset Adjust Procedure
(Refer to Figures 2 and 3)
1. Apply a train of pulses to the START CONVERT input (pin 16) so the converter is continuously converting. If using LED's on the outputs, a 200kHz conversion rate will reduce flicker.
Any offset and/or gain calibration procedures should not be implemented until devices are fully warmed up. To avoid interaction, offset must be adjusted before gain. The ranges of adjustment for the circuit of Figure 2 are guaranteed to compensate for the ADS-916's initial accuracy errors and may not be able to compensate for additional system errors.
2. Apply +305µV to the ANALOG INPUT (pin 20). 3. Adjust the offset potentiometer until the output bits are all 0's and the LSB flickers between 0 and 1.
All fixed resistors in Figure 2 should be metal-film types, and multiturn potentiometers should have TCR’s of 100ppm/°C or less to minimize drift with temperature.
Gain Adjust Procedure 1. Apply +9.999085V to the ANALOG INPUT (pin 20).
A/D converters are calibrated by positioning their digital outputs exactly on the transition point between two adjacent digital output codes. This can be accomplished by connecting LED's to the digital outputs and adjusting until certain LED's "flicker" equally between on and off. Other approaches employ digital comparators or microcontrollers to detect when the outputs change from one code to the next.
2. Adjust the gain potentiometer until the output bits are all 1's and the LSB flickers between 1 and 0. Table 1. Zero and Gain Adjust
INPUT VOLTAGE RANGE
For the ADS-916, offset adjusting is normally accomplished at the point where the output bits are 0's and the LSB just changes from a 0 to a 1. This digital output transition ideally occurs when the applied analog input is +½LSB (+305µV).
0 to +10V
Gain adjusting is accomplished when all bits are 1's and the LSB just changes from a 1 to a 0. This transition ideally occurs when the analog input is at +full scale minus 1½ LSB's (+9.999085V).

ADS-916 THERMAL REQUIREMENTS
Electrically-insulating, thermally-conductive "pads" may be installed underneath the package. Devices should be soldered to boards rather than "socketed", and of course, minimal air flow over the surface can greatly help reduce the package temperature.
All DATEL sampling A/D converters are fully characterized and specified over operating temperature (case) ranges of 0 to +70°C and –55 to +125°C. All room-temperature (TA = +25°C) production testing is performed without the use of heat sinks or forced-air cooling. Thermal impedance figures for each device are listed in their respective specification tables.
In more severe ambient conditions, the package/junction temperature of a given device can be reduced dramatically (typically 35%) by using one of DATEL's HS Series heat sinks. See Ordering Information for the assigned part number. See page 1-183 of the DATEL Data Acquisition Components Catalog for more information on the HS Series. Request DATEL Application Note AN-8, "Heat Sinks for DIP Data Converters", or contact DATEL directly, for additional information.
These devices do not normally require heat sinks, however, standard precautionary design and layout procedures should be used to ensure devices do not overheat. The ground and power planes beneath the package, as well as all pcb signal runs to and from the device, should be as heavy as possible to help conduct heat away from the package.

Notes: 1. fs = 500kHz. 2. The ADS-916 is an edge-triggered device. All internal operations are triggered by the rising edge of the start convert pulse, which may be as narrow as 50nsec. All production testing is performed at a 500kHz sampling rate with 200nsec wide start pulses. For lower sampling rates, wider start pulses may be used, however, a minimum pulse width low of 50nsec must be maintained. Figure 4. ADS-916 Timing Diagram
