# LMV321IDBVR-JSM

**JSMSEMI** · Operational Amplifier · SOT-23-5

LMV321IDBVR-JSM from JSMSEMI, 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 | IN+ | input | Non-inverting input of the amplifier; input voltage range is -0.3V to +5V per the absolute maximum ratings. |
| 2 | GND | power_in | Negative supply / ground pin of the amplifier. |
| 3 | IN- | input | Inverting input of the amplifier; input voltage range is -0.3V to +5V per the absolute maximum ratings. |
| 4 | OUT | output | Amplifier output; short circuit to GND is continuous at V+ <= 15V and TA = 25°C, with maximum output current of about 40mA. |
| 5 | VCC+ | power_in | Positive supply input, operating range 3V to 5.5V (absolute maximum 5.5V). |
