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.
16 DVDD power_in Digital core power supply; connect a 100-nF (or larger) capacitor to DGND.
17 CLK input External clock input; connect to DGND to use the internal oscillator.
18 RESET input Reset; active low.
19 GPIO3/AIN11 bidirectional General-purpose I/O; analog input 11 (ADS114S08B only).
20 GPIO2/AIN10 bidirectional General-purpose I/O; analog input 10 (ADS114S08B only).
21 GPIO1/AIN9 bidirectional General-purpose I/O; analog input 9 (ADS114S08B only).
22 GPIO0/AIN8 bidirectional General-purpose I/O; analog input 8 (ADS114S08B only).
23 REFOUT output Positive voltage reference output; connect a 1-µF to 47-µF capacitor to REFCOM if the internal voltage reference is enabled.
24 REFCOM output Negative voltage reference output; connect to AVSS.
25 NC unconnected Leave unconnected or connect to AVSS.
26 AVDD power_in Positive analog power supply; connect a 330-nF (or larger) capacitor to AVSS.
27 AVSS power_in Negative analog power supply.
28 AVSS power_in Negative analog power supply.
29 REFN0 input Negative external reference input 0.
30 REFP0 input Positive external reference input 0.
31 REFN1/AIN7 input Negative external reference input 1; analog input 7 (ADS114S08B only).
32 REFP1/AIN6 input Positive external reference input 1; analog input 6 (ADS114S08B only).
33 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
