**TECH PUBLIC** · Precision Op Amps · SOT-23-5

TPSGM8551XN5G from TECH PUBLIC, in a SOT-23-5. 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 | OUT | output | Amplifier output; rail-to-rail, continuous short-circuit to GND allowed, with 30 mA typical source and 65 mA typical sink short-circuit current. |
| 2 | -Vs | power_in | Negative chip supply voltage / GND; single-supply 2 V to 5.5V or dual-supply ±1 V to ±2.75 V. |
| 3 | +IN | input | Non-inverting (in-phase) input; signal input voltage range GND-0.5V to VDD+0.5V absolute maximum, input current ±10 mA maximum. |
| 4 | -IN | input | Inverting (reverse) input; signal input voltage range GND-0.5V to VDD+0.5V absolute maximum, input current ±10 mA maximum. |
| 5 | +Vs | power_in | Positive chip supply voltage (VDD); 2 V to 5.5 V single supply, 6 V absolute maximum to GND. |
