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 | SCLK | input | Serial clock input for SPI communication; keep low when interface is idle. |+| 2 | CS | input | Chip select input, active low; connect to DGND when not sharing SPI bus. |+| 3 | CLK | input | External clock source input; connect to DGND to enable internal oscillator. |+| 4 | DGND | power_in | Digital ground reference for digital power supply and I/O logic circuits. |+| 5 | AVSS | power_in | Negative analog power supply reference; range −0.1V to 0.1V relative to DGND in single-supply or ±2.5V in dual-supply operation. |+| 6 | AIN3/REFN1 | input | Analog input 3 or negative reference input 1; internal low-side power switch connected between this pin and AVSS. |+| 7 | AIN2 | input | Analog input 2; accepts differential or single-ended signals within −0.1V to AVDD+0.1V absolute range. |+| 8 | REFN0 | input | Negative reference input 0; differential reference voltage VREF = VREFP0 − VREFN0 must be 0.75V to 2.5V. |+| 9 | REFP0 | input | Positive reference input 0; absolute voltage range VREFN0+0.75V to AVDD+0.1V; internally buffered. |+| 10 | AIN1 | input | Analog input 1; accepts differential or single-ended signals within AVSS−0.1V to AVDD+0.1V absolute range. |+| 11 | AIN0/REFP1 | input | Analog input 0 or positive reference input 1; accepts voltages AVSS−0.1V to AVDD+0.1V; can function as primary ADC input or alternate reference input. |+| 12 | AVDD | power_in | Positive analog power supply; range 2.3V to 5.5V; decouple with 100nF or larger capacitor to AVSS. |+| 13 | DVDD | power_in | Positive digital power supply; range 2.3V to 5.5V; decouple with 100nF or larger capacitor to DGND. |+| 14 | DRDY | output | Data ready output, active low; driven low when new conversion result is ready; remains active driven even when CS is high. |+| 15 | DOUT/DRDY | tri_state | Serial data output and data ready signal combined, active low; enters high-impedance state when CS is high; MSB output first. |+| 16 | DIN | input | Serial data input for SPI communication; data latched on SCLK falling edge with 50ns setup and 25ns hold times. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Data Acquisition |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `ADS1120IPWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)+- 3D model files: `ads1120ipwr-etched.step` / `ads1120ipwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ads1120ipwr.step` / `ads1120ipwr.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/ads1120) (81 pp, sha256 `c860263ddad0839a`, retrieved 2026-09-23, tier: lcsc)+- **Datasheet language:** Chinese.
