ADS1259IPWR

Texas Instruments · Analog To Digital Converters (ADC) · TSSOP-20

ADS1259IPWR from Texas Instruments, in a TSSOP-20. 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 of the ADC.
2 AINN input Negative analog input of the ADC.
3 RESET/PWDN input Digital input for reset (active low) and power-down; hold low to power down the device.
4 START input Digital input that starts conversions when active high.
5 SYNCOUT output Digital output carrying the sync clock at fCLK/8.
6 CS input SPI chip-select input, active low; CS can be tied low.
7 SCLK input SPI serial clock input; holding SCLK low longer than 2^16 x tCLK cycles resets the SPI interface when enabled by the SPI register bit.
8 DIN input SPI serial data input, sampled on the SCLK falling edge with specified setup and hold times.
9 DOUT output SPI serial data output, updated on the SCLK rising edge.
10 DRDY output Data-ready output, active low, indicating new conversion data is available.
11 XTAL1/CLKIN input ADC clock input: DGND for the internal oscillator, external clock input when using an external clock, or crystal connection when using a crystal oscillator.
12 XTAL2 passive External crystal connection, otherwise no connection.
13 BYPASS passive Core voltage bypass pin.
14 DGND power_in Digital ground.
15 DVDD power_in Digital power supply, 2.7V to 5.25V per the electrical characteristics.
16 REFOUT output Positive reference output.
17 VREFP input Positive reference input.
18 VREFN input Negative reference input.
19 AVSS power_in Negative analog power supply and negative reference output.
20 AVDD power_in Positive analog power supply, AVSS + 4.75V to AVSS + 5.25V per the electrical characteristics.
