LT1112IS8#TRPBF

Analog Devices · Precision OpAmps · SO-8

LT1112IS8#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; with ±15 V supplies and RL = 10 kΩ it swings typically ±14.0 V (±13.0 V minimum), and with RL = 2 kΩ typically ±12.4 V (±11.0 V minimum).
2 -IN A input Inverting input of amplifier A; the common-mode input voltage range is ±13.5 V minimum at ±15 V supplies.
3 +IN A input Noninverting input of amplifier A; the inputs should never exceed the supply voltages by more than a diode drop.
4 V- power_in Negative power supply; the part is specified down to ±1.0 V minimum supply and has an absolute maximum supply of ±20 V.
5 +IN B input Noninverting input of amplifier B; the datasheet notes there is no AC-ground pin adjacent to this input, which makes its CMRR versus frequency worse than the LT1114.
6 -IN B input Inverting input of amplifier B; the common-mode input voltage range is ±13.5 V minimum at ±15 V supplies.
7 OUT B output Output of amplifier B; with ±15 V supplies and RL = 10 kΩ it swings typically ±14.0 V (±13.0 V minimum), and with RL = 2 kΩ typically ±12.4 V (±11.0 V minimum).
8 V+ power_in Positive power supply; the part is specified down to ±1.0 V minimum supply and has an absolute maximum supply of ±20 V.
