ADS1271IPWR

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

ADS1271IPWR 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 AINP input Positive analog input.
2 AINN input Negative analog input.
3 AGND power_in Analog ground.
4 AVDD power_in Analog power supply, 4.75V to 5.25V.
5 MODE input Operating mode selection: logic low for High-Speed, floating for High-Resolution, logic high for Low-Power.
6 FORMAT input Serial interface format selection: logic low for SPI, floating for Modulator output, logic high for Frame-Sync.
7 SYNC/PDWN input Synchronize or power-down input, active low; pulsing triggers synchronization, holding low enters power-down mode.
8 DIN input Serial data input for daisy-chain operation.
9 DOUT output Serial data output, MSB first, shifted on falling edge of SCLK.
10 DRDY/FSYNC bidirectional Data ready output in SPI format or Frame-Sync input in Frame-Sync format.
11 SCLK input Serial clock input for ADC data retrieval.
12 CLK input Master clock input, 0.1 to 27 MHz.
13 DVDD power_in Digital power supply, 1.65V to 3.6V.
14 DGND power_in Digital ground.
15 VREFN input Negative reference input; differential reference voltage VREF = VREFP − VREFN ranges from 2.0V to 2.65V.
16 VREFP input Positive reference input; differential reference voltage VREF = VREFP − VREFN ranges from 2.0V to 2.65V.
