AS321KTR from TECH PUBLIC, 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 | +IN | input | Non-inverting analog input to the op-amp. Common-mode input voltage range is 0 to Vcc-1.5V; input bias current is typically -20nA. |
| 2 | -Vs | power_in | Negative supply / ground reference. Connect to GND for single-supply operation, or to the negative rail (down to -20V) for split-supply operation. |
| 3 | -IN | input | Inverting analog input to the op-amp. Common-mode input voltage range is 0 to Vcc-1.5V; input bias current is typically -20nA. |
| 4 | OUT | output | Op-amp output. Rail-to-negative output swing from 0V up to Vcc-1.5V; short-circuit protected with typical short-circuit output current of 40mA. |
| 5 | +Vs | power_in | Positive supply. Single-supply range 3V to 36V (absolute max 40V); split-supply up to ±20V. Typical quiescent supply current is 0.7mA (max 1.2mA at Vo=2.5V, no load). |
