Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VIN- | input | Inverting amplifier input. Analog signal input to the negative side of the fully differential amplifier. |+| 2 | VOCM | input | Output common-mode voltage control input. Sets the DC common-mode level of the differential outputs; leave floating to self-bias at mid-supply. |+| 3 | VS+ | power_in | Amplifier positive power-supply input. Total supply range VS+ to VS- of +2.5 V to +5.5 V (±1.25 V to ±2.75 V split supply). Bypass locally with 0.1 µF. |+| 4 | VOUT+ | output | Noninverting amplifier output. Rail-to-rail differential output; pairs with VOUT- to form the differential signal. |+| 5 | VOUT- | output | Inverting amplifier output. Rail-to-rail differential output complementary to VOUT+. |+| 6 | VS- | power_in | Amplifier negative power-supply input. Tie to ground for single-supply operation or to the negative rail for split-supply. Bypass locally with 0.1 µF. |+| 7 | PD | input | Active-low power-down. Logic low puts device into low-power mode (~20 µA typical); logic high or open enables normal operation. |+| 8 | VIN+ | input | Noninverting amplifier input. Analog signal input to the positive side of the fully differential amplifier. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | MSOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## Ordering variants++- `THS4521IDGKRIDGKR`+- `THS4521IDGKRIDGKT`+- `THS4521IDGKRID`+- `THS4521IDGKRIDR`+- `THS4521IDGKRPW`+- `THS4521IDGKRDBT`++## CAD (KiCad official)++- Symbol: `THS4521IDGKR`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/ths4521i.pdf) (65 pp, sha256 `3feffebe4b1d7fe5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
