TP2311-TR from 3PEAK, in a SOT-23-5. 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 | Out | output | Op-amp output. Rail-to-rail output stage capable of sourcing/sinking up to ~70 mA (1.0 V drop typ), short-circuit current 100 mA min, 130 mA typ. Open-loop output impedance ~125 Ohm at 1 kHz, closed-loop ~0.2 Ohm at 1 MHz (G=1). |
| 2 | -Vs | power_in | Negative supply rail (V-). For single-supply operation tie to GND; for dual-supply operation connect to negative rail. Total supply (V+ minus V-) is 2.2 V to 5.5 V (7.0 V absolute maximum). |
| 3 | +In | input | Non-inverting input. Rail-to-rail input, common-mode range V- - 0.1 V to V+ - 0.1 V. Very low input bias current (0.3 pA typ at 27 C) and 50 uV max input offset voltage. Protected by ESD diodes to each supply; limit input current to <10 mA if input exceeds supply by >500 mV. |
| 4 | -In | input | Inverting input. Rail-to-rail input, common-mode range V- - 0.1 V to V+ - 0.1 V. Very low input bias current (0.3 pA typ at 27 C). Protected by ESD diodes to each supply; limit input current to <10 mA if input exceeds supply by >500 mV. |
| 5 | +Vs | power_in | Positive supply rail (V+). Total supply (V+ minus V-) is 2.2 V to 5.5 V (7.0 V absolute maximum). Supplies must be established simultaneously with or before any input signal is applied. Decouple locally with a 0.1 uF ceramic capacitor to V-. |
