ADS8166IRHBT from Texas Instruments, in a VQFN-32-EP(5x5). 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 power supply pin.
2 DECAP power_in Internal power supply decoupling pin; connect a 1µF capacitor to GND.
3 REFIO bidirectional External reference voltage input or internal reference 4.096V output; connect a 1µF capacitor to GND.
4 REFM input Reference ground potential; externally short to GND.
5 REFP bidirectional Reference buffer output and ADC reference input; externally short pins 5 and 6 together.
6 REFP bidirectional Reference buffer output and ADC reference input; externally short pins 5 and 6 together.
7 REFby2 output Analog output with voltage equal to half the REFP voltage; connect a 1µF capacitor to GND.
8 AIN-COM input Common analog input used in pseudo-differential or single-ended input configurations.
9 AIN0 input Analog input channel 0.
10 AIN1 input Analog input channel 1.
11 AIN2 input Analog input channel 2.
12 AIN3 input Analog input channel 3.
13 AIN4 input Analog input channel 4.
14 AIN5 input Analog input channel 5.
15 AIN6 input Analog input channel 6.
16 AIN7 input Analog input channel 7.
17 ADC-INP input Positive ADC analog input.
18 MUXOUT-P output MUX positive analog output.
19 MUXOUT-M output MUX negative analog output.
20 ADC-INM input Negative ADC analog input.
21 GND power_in Ground power supply pin.
22 ALERT output Digital ALERT output; active high; logical OR of all enabled channel ALERTs.
23 CS input Chip-select input; active low; device starts converting on rising edge of CS.
24 SDI input Serial data input pin for device commands and configuration data.
25 SCLK input Serial clock input pin for SPI interface timing.
26 SDO-0 output Serial data output 0 for device data.
27 SDO-1/SEQSTS output Multifunction output; indicates channel scanning status or serial data output 1 in dual SDO mode.
28 READY output Multifunction output; reflects conversion status when CS is high; protocol-dependent when CS is low.
29 RST input Asynchronous reset input; active low; low pulse resets device to default states.
30 DVDD power_in Interface power supply pin; connect a 1µF capacitor to GND.
31 GND power_in Ground power supply pin.
32 AVDD power_in Analog power supply pin; connect a 1µF capacitor to GND.
33 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
