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. |
