ADS1146IPWR

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

ADS1146IPWR 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 DVDD power_in Digital power supply; connect a 0.1-µF capacitor to DGND
2 DGND power_in Digital ground
3 CLK input External clock input; tie to DGND to activate the internal oscillator
4 RESET input Reset (active low)
5 REFP input Positive external reference input
6 REFN input Negative external reference input
7 AINP input Positive analog input
8 AINN input Negative analog input
9 AVSS power_in Negative analog power supply
10 AVDD power_in Positive analog power supply; connect a 0.1-µF capacitor to AVSS
11 START input Conversion start
12 CS input Chip select (active low)
13 DRDY output Data ready (active low)
14 DOUT/DRDY tri_state Serial data output or data out combined with data ready; enters high-impedance state when CS is high
15 DIN input Serial data input
16 SCLK input Serial clock input
