TS321AILT from STMicroelectronics, 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 | Output | output | Op-amp output. Delivers up to ~40 mA source / 20 mA sink (Vcc = 15 V); short-circuit current to ground ~40-60 mA. High-level output reaches VCC+ − 1.5 V (typ) and low-level output ≤ 15 mV into 10 kΩ. Output is stable with high capacitive loads. |
| 2 | VCC- | power_in | Negative supply / ground pin. Tied to ground in single-supply operation (3 to 30 V on VCC+) or to a negative rail down to −15 V in dual-supply operation. |
| 3 | Non-inverting input | input | Non-inverting (+) input to the op-amp. Input common-mode range includes VCC- (ground in single-supply use) and extends up to (VCC+ − 1.5 V). Input bias current ~20 nA typ; differential input voltage rating ±32 V. |
| 4 | Inverting input | input | Inverting (−) input to the op-amp. Same electrical properties as the non-inverting input: Vicm includes ground, Ib ≈ 20 nA typ, Vid rating ±32 V. Input offset voltage ≤ 2 mV max on the TS321A grade. |
| 5 | VCC+ | power_in | Positive supply pin. Operating range 3 to 30 V single-supply (or up to ±15 V dual-supply); absolute max 32 V (±16 V dual). Typical supply current 500 µA at VCC+ = 5 V, 600 µA at 30 V. |
