# OPA698IDR

**Texas Instruments** · Operational Amplifier · SOIC-8

OPA698IDR from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | No internal connection; the datasheet says to float this pin. |
| 2 | Inverting Input | input | Inverting input of the voltage-feedback op amp. |
| 3 | Noninverting Input | input | Noninverting input of the voltage-feedback op amp. |
| 4 | -VS | power_in | Negative (lowest) supply; the recommended total supply range is ±2.5 V to ±6 V. |
| 5 | VL | input | Lower limiter input that sets the negative output limit; limiter voltage range is ±(VS - 0.7) V. |
| 6 | Output | output | Amplifier output, which is held within the limits set by VL and VH when driven beyond them. |
| 7 | +VS | power_in | Positive (highest) supply; absolute maximum total supply voltage is 13 V. |
| 8 | VH | input | Upper limiter input that sets the positive output limit; limiter voltage range is ±(VS - 0.7) V. |

## CAD (KiCad official)

- Symbol: `OPA698IDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `opa698idr-etched.step` / `opa698idr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa698idr.step` / `opa698idr.glb` are the bare package body.
