Dual comparators BA10393 / BA10393F / BA10393N The BA10393, BA10393F, and BA10393N are dual comparators with open-collector output which allows wired OR connections. The operating power supply voltage ranges from 2 to 36V for a single power supply and ± 1 to ± 18V for a dual power supply. The packages are as follows: DIP 8-pin (BA10393), SOP 8-pin (BA10393F), and SIP 8-pin (BA10393N).
•1)Features Wide operating voltage range. (Single power supply: 2 to 36V, dual power supply: ± 1 to ± 18V) 2) Low current dissipation. (0.4mA typ. at VCC = 5V) 3) Low input offset voltage. (25nA typ. at VCC = 5V) and low input offset voltage. (typically ±1.0mV at VCC = 5V)
4) Wide common-mode input voltage. (0 to VCC – 1.5V) 5) Open collector output. 6) Compatible with 393 comparators from other manufacturers.
