NCV321SN3T1G from onsemi, in a TSOP-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 of the op-amp. Common-mode input range spans from V- - 0.2 V up to V+ + 0.2 V (rail-to-rail input); guaranteed 0 V to (V+ - 1 V) for CMRR ≥ 50 dB. Maximum input current 10 mA. |
| 2 | V- | power_in | Negative supply / ground reference. Typically tied to GND in single-supply operation. Supply span V+ to V- is 2.7 V to 5.5 V (absolute max). |
| 3 | -IN | input | Inverting analog input of the op-amp. Rail-to-rail input range identical to +IN; differential input voltage limited to ±V_S. Maximum input current 10 mA. |
| 4 | OUTPUT | output | Rail-to-rail push-pull output. Swings to within ~10 mV of either rail at 10 kΩ load. Output short-circuit current typically 60 mA sourcing / 160 mA sinking at V+ = 5 V; continuous short-circuit rated but sustained currents >45 mA can degrade reliability. |
| 5 | V+ | power_in | Positive supply. Operating range 2.7 V to 5.0 V (absolute max 5.5 V). Quiescent supply current I_CC typically 130 µA at V+ = 5 V. |
