**Analog Devices** · Operational Amplifier · SOIC-8

LT1211CS8#PBF from Analog Devices, in a SOIC-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; swings to ground while sinking current and provides at least 20mA minimum output drive. |
| 2 | -IN A | input | Inverting input of amplifier A; inputs can be driven beyond the supplies without damage or phase reversal of the output. |
| 3 | +IN A | input | Non-inverting input of amplifier A; input voltage range includes ground and inputs can be driven beyond the supplies without damage or phase reversal. |
| 4 | V- | power_in | Negative supply; total supply voltage from V+ to V- is limited to 36V absolute maximum, and the part operates on any supply greater than 2.5V and less than 36V total. |
| 5 | +IN B | input | Non-inverting input of amplifier B; input voltage range includes ground and inputs can be driven beyond the supplies without damage or phase reversal. |
| 6 | -IN B | input | Inverting input of amplifier B; inputs can be driven beyond the supplies without damage or phase reversal of the output. |
| 7 | OUT B | output | Output of amplifier B; swings to ground while sinking current and provides at least 20mA minimum output drive. |
| 8 | V+ | power_in | Positive supply; total supply voltage from V+ to V- is limited to 36V absolute maximum, and the part operates on any supply greater than 2.5V and less than 36V total. |
