# OPA2333AIDRBT

**Texas Instruments** · Precision Op Amps · SON-8-EP(3x3)

OPA2333AIDRBT from Texas Instruments, in a SON-8-EP(3x3). 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 A | output | Channel A output of the dual op amp; the output stage swings to within 50 mV of the positive supply rail and can be pulled to or slightly below the negative rail with an external pulldown resistor. |
| 2 | -IN A | input | Channel A inverting input; the input common-mode range extends 0.1 V beyond each supply rail. |
| 3 | +IN A | input | Channel A non-inverting input; the input common-mode range extends 0.1 V beyond each supply rail. |
| 4 | V- | power_in | Negative (lowest) power supply; operating supply range is 1.8 V to 5.5 V total, and the exposed die pad should be connected to V- or left unconnected. |
| 5 | +IN B | input | Channel B non-inverting input; the input common-mode range extends 0.1 V beyond each supply rail. |
| 6 | -IN B | input | Channel B inverting input; the input common-mode range extends 0.1 V beyond each supply rail. |
| 7 | OUT B | output | Channel B output of the dual op amp; the output stage swings to within 50 mV of the positive supply rail and can be pulled to or slightly below the negative rail with an external pulldown resistor. |
| 8 | V+ | power_in | Positive (highest) power supply; operating supply range is 1.8 V to 5.5 V and the absolute maximum is 7 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
