# OPA333AIDBVR-MS

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

OPA333AIDBVR-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 | Output of the amplifier, rail-to-rail, swinging within 50 mV of the rails. |
| 2 | V- | power_in | Negative (lowest) power supply; single supply operation from 1.8 V to 5.5 V, or dual supply ±0.9 V to ±2.75 V. |
| 3 | +IN | input | Positive (noninverting) input; common-mode range extends 100 mV beyond the rails. |
| 4 | -IN | input | Negative (inverting) input; common-mode range extends 100 mV beyond the rails. |
| 5 | V+ | power_in | Positive (highest) power supply; single supply operation from 1.8 V to 5.5 V, or dual supply ±0.9 V to ±2.75 V. |
