# LMV821ICT

**STMicroelectronics** · Operational Amplifier · SC-70-5

LMV821ICT from STMicroelectronics, 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 | IN+ | input | Non-inverting input; input voltage range is Vcc- - 0.2 V to Vcc+ - 1 V and absolute maximum is Vcc- - 0.3 V to Vcc+ + 0.3 V. |
| 2 | VCC- | power_in | Negative supply (ground in single-supply use); supply range Vcc is 2.5 V to 5.5 V, absolute maximum 6 V. |
| 3 | IN- | input | Inverting input; input voltage range is Vcc- - 0.2 V to Vcc+ - 1 V and absolute maximum is Vcc- - 0.3 V to Vcc+ + 0.3 V. |
| 4 | OUT | output | Amplifier output with rail-to-rail swing, within 150 mV max of the rails into a 2 kΩ load to Vcc/2. |
| 5 | VCC+ | power_in | Positive supply, 2.5 V to 5.5 V with a 10 nF decoupling capacitor recommended close to the pin. |
