LT1211CS8#TRPBF from Analog Devices, in a SOP-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 | Amplifier A output, with minimum output drive of 20mA and continuous short-circuit duration allowed. |
| 2 | -IN A | input | Amplifier A inverting input, which can be driven beyond the supplies without damage or phase reversal, with input current limited to ±15mA. |
| 3 | +IN A | input | Amplifier A non-inverting input, whose voltage range includes ground, with input current limited to ±15mA. |
| 4 | V- | power_in | Negative supply (ground in single-supply use), with total supply V+ to V- of at most 36V. |
| 5 | +IN B | input | Amplifier B non-inverting input, whose voltage range includes ground, with input current limited to ±15mA. |
| 6 | -IN B | input | Amplifier B inverting input, which can be driven beyond the supplies without damage or phase reversal, with input current limited to ±15mA. |
| 7 | OUT B | output | Amplifier B output, with minimum output drive of 20mA and continuous short-circuit duration allowed. |
| 8 | V+ | power_in | Positive supply, operating with total supply (V+ to V-) greater than 2.5V and no more than 36V. |
