LT1112S8#TRPBF

Analog Devices · Operational Amplifier · SO-8

LT1112S8#TRPBF from Analog Devices, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT A output Output of amplifier A; the datasheet specifies indefinite output short-circuit duration.
2 -IN A input Inverting input of amplifier A; differential input current is limited to ±10mA absolute maximum, and differential input voltages above 1V require limiting resistance.
3 +IN A input Noninverting input of amplifier A; input voltage (equal to supply voltage) is rated to ±20V absolute maximum.
4 V- power_in Negative supply; the device is guaranteed down to ±1.0V minimum supply and the absolute maximum supply is ±20V.
5 +IN B input Noninverting input of amplifier B; input voltage (equal to supply voltage) is rated to ±20V absolute maximum.
6 -IN B input Inverting input of amplifier B; differential input current is limited to ±10mA absolute maximum, and differential input voltages above 1V require limiting resistance.
7 OUT B output Output of amplifier B; the datasheet specifies indefinite output short-circuit duration.
8 V+ power_in Positive supply; the device is guaranteed down to ±1.0V minimum supply and the absolute maximum supply is ±20V.
