# OPA2333AIDRBR

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

OPA2333AIDRBR 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 | Output A; rail-to-rail output within 50 mV of supply rails. |
| 2 | -IN A | input | Inverting input A; input diode-clamped to supply rails, tolerating ±0.3 V beyond limits with 10 mA current limit. |
| 3 | +IN A | input | Noninverting input A; input diode-clamped to supply rails, tolerating ±0.3 V beyond limits with 10 mA current limit. |
| 4 | V- | power_in | Negative power supply; supply voltage 1.8 V to 5.5 V. |
| 5 | +IN B | input | Noninverting input B; input diode-clamped to supply rails, tolerating ±0.3 V beyond limits with 10 mA current limit. |
| 6 | -IN B | input | Inverting input B; input diode-clamped to supply rails, tolerating ±0.3 V beyond limits with 10 mA current limit. |
| 7 | OUT B | output | Output B; rail-to-rail output within 50 mV of supply rails. |
| 8 | V+ | power_in | Positive power supply; supply voltage 1.8 V to 5.5 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `OPA2333AIDRBR`
- Footprint: `Package_SON:WSON-8-1EP_3x3mm_P0.5mm_EP1.6x2.0mm`
- 3D model: SON-8-EP(3x3) (KiCad packages3D, STEP)
- 3D model files: `opa2333aidrbr-etched.step` / `opa2333aidrbr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa2333aidrbr.step` / `opa2333aidrbr.glb` are the bare package body.
