ADS112U04IPWR

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-16

ADS112U04IPWR from Texas Instruments, in a TSSOP-16. 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 GPIO1 bidirectional General-purpose input/output 1; input voltage is limited to DGND to DVDD.
2 GPIO0 bidirectional General-purpose input/output 0; input voltage is limited to DGND to DVDD.
3 RESET input Reset input, active low; input voltage is limited to DGND to DVDD.
4 DGND power_in Digital ground; the DVDD to DGND digital supply range is 2.3 V to 5.5 V.
5 AVSS power_in Negative analog power supply; in unipolar operation AVSS to DGND is limited to -0.1 V to 0.1 V.
6 AIN3 input Analog input 3; with the PGA disabled, the absolute input voltage is limited to AVSS - 0.1 V to AVDD + 0.1 V.
7 AIN2 input Analog input 2; with the PGA disabled, the absolute input voltage is limited to AVSS - 0.1 V to AVDD + 0.1 V.
8 REFN input Negative reference input; V(REFN) must stay between AVSS - 0.1 V and V(REFP) - 0.75 V.
9 REFP input Positive reference input; V(REFP) must stay between V(REFN) + 0.75 V and AVDD + 0.1 V.
10 AIN1 input Analog input 1; with the PGA disabled, the absolute input voltage is limited to AVSS - 0.1 V to AVDD + 0.1 V.
11 AIN0 input Analog input 0; with the PGA disabled, the absolute input voltage is limited to AVSS - 0.1 V to AVDD + 0.1 V.
12 AVDD power_in Positive analog power supply, 2.3 V to 5.5 V above AVSS in unipolar operation; connect a 100-nF (or larger) capacitor to AVSS.
13 DVDD power_in Positive digital power supply, 2.3 V to 5.5 V above DGND; connect a 100-nF (or larger) capacitor to DGND.
14 GPIO2/DRDY bidirectional General-purpose input/output 2 or data ready; active low.
15 TX output Serial data output of the 2-wire UART interface.
16 RX input Serial data input of the 2-wire UART interface; input voltage is limited to DGND to DVDD.
