# TSB612IYDT

**STMicroelectronics** · Operational Amplifier · SO-8

TSB612IYDT 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 | Out1 | output | Amplifier 1 rail-to-rail output, which swings to within 100 mV max of the positive rail and 110 mV max of the negative rail with a 10 kΩ load at 36 V. |
| 2 | In1- | input | Amplifier 1 inverting input, with input current limited to 10 mA max by a series resistor and common-mode range of (VCC-) - 0.1 V to (VCC+) - 1 V. |
| 3 | In1+ | input | Amplifier 1 non-inverting input, with input current limited to 10 mA max by a series resistor and common-mode range of (VCC-) - 0.1 V to (VCC+) - 1 V. |
| 4 | VCC- | power_in | Negative supply voltage (ground in single-supply use) for both amplifiers, with total supply range of 2.7 V to 36 V. |
| 5 | In2+ | input | Amplifier 2 non-inverting input, with input current limited to 10 mA max by a series resistor and common-mode range of (VCC-) - 0.1 V to (VCC+) - 1 V. |
| 6 | In2- | input | Amplifier 2 inverting input, with input current limited to 10 mA max by a series resistor and common-mode range of (VCC-) - 0.1 V to (VCC+) - 1 V. |
| 7 | Out2 | output | Amplifier 2 rail-to-rail output, which swings to within 100 mV max of the positive rail and 110 mV max of the negative rail with a 10 kΩ load at 36 V. |
| 8 | VCC+ | power_in | Positive supply voltage for both amplifiers, operating range 2.7 V to 36 V (40 V absolute maximum), with a 22 nF bypass capacitor recommended close to the pin. |
