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 | VREF | power_in | Reference voltage input; acceptable range 50mV to VCC sets the full-scale analog input range. |+| 2 | +In | input | Noninverting analog input; operating range must be maintained within GND-200mV to VCC+200mV for proper linearity. |+| 3 | -In | input | Inverting analog input with operating range of GND-200mV to GND+1.0V; connect to local ground or remote ground sense reference. |+| 4 | GND | power_in | Ground reference for all analog and digital circuits. |+| 5 | CS/SHDN | input | Chip select (active low) that initiates conversion on falling edge; high level activates shutdown mode with 3μA maximum quiescent current. |+| 6 | DOUT | tri_state | Serial data output transmitting 12-bit conversion result MSB-first on DCLOCK falling edge; tri-states when CS is high. |+| 7 | DCLOCK | input | Data clock input synchronizing serial data output; operating frequency range 10kHz to 3.2MHz maximum. |+| 8 | +VCC | power_in | Power supply input with operating range 2.0V to 5.25V; specified performance guaranteed over 2.7V to 5.25V range. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Data Acquisition |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `ADS7822U`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `ads7822u-etched.step` / `ads7822u-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ads7822u.step` / `ads7822u.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ads7822) (31 pp, sha256 `889c901a1116a5b2`, retrieved 2026-09-23, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.2`, primary `claude-haiku-4-5-20251001` (text), consensus `claude-sonnet-5` (agreed), guards: pin_guards 0.1: passed.
