# LMV721IDCKR

**Texas Instruments** · Operational Amplifier · SC-70-5

LMV721IDCKR from Texas Instruments, in a SC-70-5. 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 | OUT | output | Amplifier output, which swings rail-to-rail (for example 120 mV from either rail at 2.2 V into 600 Ω, and 50 mV from either rail at 2.2 V into 2 kΩ). |
| 2 | VCC− | power_in | Negative supply rail; the supply range is 2.2 V to 5.5 V measured as VCC+ − VCC−, and the datasheet tests this pin at GND. |
| 3 | IN+ | input | Non-inverting input whose common-mode range includes ground (−0.3 V to 1.3 V at 2.2 V supply, and −0.3 V to 4.1 V at 5 V supply). |
| 4 | IN− | input | Inverting input that shares the same input common-mode voltage range as IN+. |
| 5 | VCC+ | power_in | Positive supply rail; the operating range is 2.2 V to 5.5 V with a 6 V absolute maximum supply voltage. |
