LT1636IS8#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 | NULL | passive | Offset null terminal; a 10k potentiometer between pins 1 and 8 with its wiper to V- nulls the input offset voltage over a range of at least ±1mV. |
| 2 | -IN | input | Inverting input; the inputs take 44V differential and common mode and are protected to 22V below V- by internal 1k resistors. |
| 3 | +IN | input | Non-inverting input; the LT1636 operates with this input up to 44V above V- regardless of V+, with no output phase reversal for inputs 5V below V-. |
| 4 | V- | power_in | Negative supply pin; the LT1636 operates on single or split supplies with a total voltage of 2.7V to 44V and reverse battery protection to 27V. |
| 5 | SHDN | input | Shutdown pin; it can be taken up to 32V above V- and driving it 1.2V above V- reduces supply current to about 4µA with output leakage below 1µA. |
| 6 | OUT | output | Output swings to both supplies and drives 18mA, and the LT1636 is unity-gain stable into capacitive loads up to 10,000pF with a 0.22µF and 150Ω compensation network. |
| 7 | V+ | power_in | Positive supply pin; it should be bypassed with about 0.01µF within an inch of the pin, and the output can be pulled up to 27V beyond V+ with V+ below 0.5V. |
| 8 | NULL | passive | Offset null terminal; connects to the offset nulling potentiometer with its wiper tied to V- as described for pin 1. |
