**STMicroelectronics** · Precision Op Amps · SO-8

TS27L2AIDT from STMicroelectronics, 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 | Output 1 | output | Output of first amplifier with voltage swing from 50mV (low) to 8.6-9V (high) at 1MΩ load and maximum output current ±30mA. |
| 2 | Inverting Input 1 | input | Inverting input of first amplifier with input voltage range -0.3V to 18V, input offset current 1-200pA, and input bias current 1-300pA. |
| 3 | Non-inverting Input 1 | input | Non-inverting input of first amplifier with common-mode voltage range 0 to VCC+-1.5V, input offset current 1-200pA, and input bias current 1-300pA. |
| 4 | VCC- | power_in | Negative supply rail operating at 0V for single-supply mode or negative voltage for dual-supply mode; serves as reference for all signal voltages. |
| 5 | Non-inverting Input 2 | input | Non-inverting input of second amplifier with common-mode voltage range 0 to VCC+-1.5V, input offset current 1-200pA, and input bias current 1-300pA. |
| 6 | Inverting Input 2 | input | Inverting input of second amplifier with input voltage range -0.3V to 18V, input offset current 1-200pA, and input bias current 1-300pA. |
| 7 | Output 2 | output | Output of second amplifier with voltage swing from 50mV (low) to 8.6-9V (high) at 1MΩ load and maximum output current ±30mA. |
| 8 | VCC+ | power_in | Positive supply rail with operating voltage range 3V to 16V and absolute maximum rating of 18V; supplies power and biasing to both amplifiers. |
