TS271CDT from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Offset Null 1 | passive | Offset null pin used with pin 5 for external offset voltage compensation, connected via an external resistor/potentiometer network as shown in the offset voltage null circuit. |
| 2 | Inverting Input | input | Inverting input of the operational amplifier; common mode input voltage range is 0 to VCC+ - 1.5V. |
| 3 | Non-inverting Input | input | Non-inverting input of the operational amplifier; common mode input voltage range is 0 to VCC+ - 1.5V. |
| 4 | VCC- | power_in | Negative (or ground) supply pin; total supply voltage (VCC+ to VCC-) ranges from 3V to 16V, with absolute maximum of 18V. |
| 5 | Offset Null 2 | passive | Offset null pin used with pin 1 for external offset voltage compensation, connected via an external resistor/potentiometer network as shown in the offset voltage null circuit. |
| 6 | Output | output | Amplifier output, capable of swinging to ground, with output short-circuit current typically 60mA and sink current typically 45mA. |
| 7 | VCC+ | power_in | Positive supply pin; operating supply voltage range is 3V to 16V with an absolute maximum rating of 18V. |
| 8 | ISet | passive | Bias-setting pin connected through an external resistor (Rset) to VCC- or ground to program the internal bias current (ISET), selectable typically as 1.5µA, 25µA, or 130µA to trade off speed versus supply current. |
