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 | GND | power_in | Ground pin; one of three GND pins (1, 21, 31) that must be connected to the system ground. |+| 2 | DECAP | power_in | Connect a 1µF capacitor to GND for the internal power supply. |+| 3 | REFIO | bidirectional | External reference voltage input; the internal reference is a 4.096V output, and a 1µF capacitor must be connected from this pin to GND. |+| 4 | REFM | passive | Reference ground potential; short this pin to GND externally. |+| 5 | REFP | bidirectional | Reference buffer output and ADC reference input; short pins 5 and 6 together. |+| 6 | REFP | bidirectional | Reference buffer output and ADC reference input; short pins 5 and 6 together. |+| 7 | REFby2 | output | Output voltage equals half the voltage on the REFP pin; connect a 1µF capacitor from this pin to GND. |+| 8 | AIN-COM | passive | Common analog input; connect to GND for single-ended operation or to REFby2 for pseudo-differential operation, as set by the COM_CFG register. |+| 9 | AIN0 | passive | Analog input channel 0. |+| 10 | AIN1 | passive | Analog input channel 1. |+| 11 | AIN2 | passive | Analog input channel 2. |+| 12 | AIN3 | passive | Analog input channel 3. |+| 13 | AIN4 | passive | Analog input channel 4. |+| 14 | AIN5 | passive | Analog input channel 5. |+| 15 | AIN6 | passive | Analog input channel 6. |+| 16 | AIN7 | passive | Analog input channel 7. |+| 17 | ADC-INP | passive | Positive ADC analog input. |+| 18 | MUXOUT-P | output | MUX positive analog output. |+| 19 | MUXOUT-M | output | MUX negative analog output. |+| 20 | ADC-INM | passive | Negative ADC analog input. |+| 21 | GND | power_in | Ground pin; one of three GND pins (1, 21, 31) that must be connected to the system ground. |+| 22 | ALERT | output | Digital ALERT output, active high; it is the logical OR of the enabled channel ALERTs. |+| 23 | CS | input | Active-low chip-select; the device starts converting the active channel on the rising edge of CS, and the SDO-x pins go Hi-Z when CS is high. |+| 24 | SDI | input | Serial data input that transfers data or commands into the device. |+| 25 | SCLK | input | Clock input for the serial interface; all system-synchronous data transfer protocols are timed with respect to SCLK. |+| 26 | SDO-0 | output | Serial communication data output 0. |+| 27 | SDO-1/SEQSTS | output | Multifunction output: by default indicates channel scanning status in auto and custom sequence modes, and functions as serial data output SDO-1 in dual SDO mode. |+| 28 | READY | output | Multifunction output that reflects conversion status when CS is high, going low while a conversion is in process. |+| 29 | RST | input | Asynchronous reset input; a low pulse resets the device and returns all register bits to their default states. |+| 30 | DVDD | power_in | Interface power supply pin, with DVDD range of 1.65V to 5.5V; connect a 1µF capacitor from this pin to GND. |+| 31 | GND | power_in | Ground pin; one of three GND pins (1, 21, 31) that must be connected to the system ground. |+| 32 | AVDD | power_in | Analog power supply pin, with AVDD range of 3V to 5.5V; connect a 1µF capacitor from this pin to GND. |+| 33 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | VQFN-32-EP(5x5) |+| Category | Data Acquisition |+| Pins | 33 |++## CAD (KiCad official)++- Symbol: `ADS8167IRHBR`+- Footprint: `Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.3x3.3mm`+- 3D model: VQFN-32-EP(5x5) (KiCad packages3D, STEP)+- 3D model files: `ads8167irhbr-etched.step` / `ads8167irhbr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ads8167irhbr.step` / `ads8167irhbr.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/ads8166) (86 pp, sha256 `fa97ed7844ff4a62`, retrieved 2026-10-08, tier: lcsc)+- **Datasheet language:** Chinese.
