ADS114S08BIRHBR

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

ADS114S08BIRHBR 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 AINCOM input Common analog input for single-ended measurements.
2 AIN5 input Analog input 5.
3 AIN4 input Analog input 4.
4 AIN3 input Analog input 3.
5 AIN2 input Analog input 2.
6 AIN1 input Analog input 1.
7 AIN0 input Analog input 0.
8 START/SYNC input Start conversion.
9 CS input Chip select; active low.
10 DIN input Serial data input.
11 SCLK input Serial clock input.
12 DOUT/DRDY tri_state Serial data output combined with data ready; active low.
13 DRDY output Data ready; active low.
14 DGND power_in Digital ground.
15 IOVDD power_in Digital I/O power supply; in case IOVDD is not tied to DVDD, connect a 100-nF (or larger) capacitor to DGND.
