# LMV321TDTR

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

LMV321TDTR from XBLW, 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; input voltage range is -0.1V to +5.6V with VS = 5.5V, and common-mode input is limited to (-VS) - 0.5V to (+VS) + 0.5V. |
| 2 | -VS | power_in | Negative supply pin (ground in single-supply use); supply voltage V+ to V- must stay within 7.5V absolute maximum, with 2.1V to 5.5V recommended operation. |
| 3 | -IN | input | Inverting input; common-mode input is limited to (-VS) - 0.5V to (+VS) + 0.5V. |
| 4 | OUT | output | Rail-to-rail amplifier output. |
| 5 | +VS | power_in | Positive supply pin; operates on 2.1V to 5.5V with 7.5V absolute maximum between V+ and V-. |
