TSM103WAIDT from STMicroelectronics, in a SOIC-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 | Output 1 | output | Output of op-amp 1 (OP1). OP1's non-inverting input is internally connected to the 2.5V Vref, making OP1 useful as a reference buffer/comparator. VOH typically reaches (VCC+ - 3V) with 2k load; VOL typically 5mV with 10k load. |
| 2 | Inverting Input 1 | input | Inverting input of op-amp 1 (OP1). Typical input bias current 20nA. Input voltage range must stay within -0.3V to VCC+0.3V and common-mode range from 0V (ground) up to (VCC+ - 1.5V). |
| 3 | Non-inverting Input 1 / VRef | passive | Non-inverting input of OP1, exposed externally as the 2.5V voltage reference node (VRef / cathode of internal shunt reference). Provides a fixed 2.5V (±0.7% for TSM103W, ±0.4% for TSM103WA) with cathode current 1 to 100 mA; dynamic impedance 0.2Ω typ. Used as reference for OP1's non-inverting comparator/buffer input. |
| 4 | VCC- | power_in | Negative supply / ground pin. For single-supply operation connect to GND; for split-supply operation connect to negative rail. Total supply range 3 to 32V (±1.5 to ±16V split). |
| 5 | Non-inverting Input 2 | input | Non-inverting input of op-amp 2 (OP2), the independent op-amp. Input common-mode range includes ground (0V) up to (VCC+ - 1.5V). Typical input bias current 20nA. |
| 6 | Inverting Input 2 | input | Inverting input of op-amp 2 (OP2). Typical input bias current 20nA, input offset current 2nA typ. |
| 7 | Output 2 | output | Output of op-amp 2 (OP2), the independent op-amp. Output can source 40mA typ / sink 20mA typ; output voltage swing 0V to (VCC - 1.5V). |
| 8 | VCC+ | power_in | Positive supply pin. Operating range 3 to 32V single supply (or up to ±16V split). Total supply current typically 0.7mA at VCC+=5V (no load, excluding Vref current). Absolute maximum 36V. |
