ADS8167IRHBR

Texas Instruments · Analog To Digital Converters (ADC) · VQFN-32-EP(5x5)

ADS8167IRHBR 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 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).
