# OPA376AIDBVR-MS

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

OPA376AIDBVR-MS from MSKSEMI, 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 | OUT | output | Amplifier output. |
| 2 | V- | power_in | Supply pin labeled V-; the pin table describes it as "Positive (highest) power supply", which conflicts with the pin name and with the V+ entry, so its polarity must be verified before use. |
| 3 | +IN | input | Positive (noninverting) input. |
| 4 | -IN | input | Negative (inverting) input. |
| 5 | V+ | power_in | Supply pin labeled V+; the pin table describes it as "Negative (lowest) power supply", which conflicts with the pin name and with the V- entry, so its polarity must be verified before use. |
