BA10393N

Standard ICs 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. •Block diagram BA10393 / BA10393F BA10393N OUT1 1 8 VCC – IN1 2 7 OUT2 6 – IN2 5 + IN2 + 4 5 6 7 8 VEE + IN2 – IN2 OUT2 VCC – 3 2ch + IN1 4 + 2 VEE + – IN1 3 2ch – 1 + IN1 + OUT1 – 1ch 1ch – 1 Standard ICs BA10393 / BA10393F / BA10393N •Internal circuit configuration VCC OUT + IN – IN GND •Absolute maximum ratings (Ta = 25°C) Parameter Symbol Limits Unit BA10393 BA10393F BA10393N VCC 36 ( ± 18) 36 ( ± 18) 36 ( ± 18) V Power dissipation Pd 800∗ 550∗ 900∗ mW Differential input voltage VID ± VCC ± VCC ± VCC Power supply voltage V VI – 0.3 ~ VCC – 0.3 ~ VCC – 0.3 ~ VCC V Operating temperature Topr – 40 ~ + 85 – 40 ~ + 85 – 40 ~ + 85 °C Storage temperature Tstg – 55 ~ + 125 – 55 ~ + 125 – 55 ~ + 125 °C Common-mode input voltage ∗ Refer to the Pd characteristics diagram.
