# TSX632IQ2T

**STMicroelectronics** · Operational Amplifier · WDFN-8(2x2)

TSX632IQ2T from STMicroelectronics, in a WDFN-8(2x2). 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 | OUT1 | output | Output of amplifier 1, rail-to-rail. |
| 2 | IN1- | input | Inverting input of amplifier 1, rail-to-rail with common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1, rail-to-rail with common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 4 | VCC- | power_in | Negative supply voltage (ground in single-supply use). |
| 5 | IN2+ | input | Non-inverting input of amplifier 2, rail-to-rail with common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 6 | IN2- | input | Inverting input of amplifier 2, rail-to-rail with common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 7 | OUT2 | output | Output of amplifier 2, rail-to-rail. |
| 8 | VCC+ | power_in | Positive supply voltage, 3.3 V to 16 V operating (18 V absolute maximum); 10 nF decoupling advised close to pin. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

## CAD (KiCad official)

- Symbol: `TSX632IQ2T`
- Footprint: `Package_DFN_QFN:WDFN-8-1EP_2x2mm_P0.5mm_EP0.8x1.2mm`
- 3D model: WDFN-8(2x2), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.75 mm nominal WSON height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `tsx632iq2t-etched.step` / `tsx632iq2t-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tsx632iq2t.step` / `tsx632iq2t.glb` are the bare package body.
