ADS1259IPW

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

ADS1259IPW 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
2 AINN input Negative analog input
3 RESET/PWDN input Reset/Power-Down control; active low; hold low for power-down
4 START input Start conversions; active high
5 SYNCOUT output Sync clock output at fCLK/8
6 CS input SPI chip-select; active low
7 SCLK input SPI serial clock input; period 1.8 tCLK minimum
8 DIN input SPI serial data input; setup time 35 ns before SCLK falling edge
9 DOUT tri_state SPI serial data output; tri-state when CS high; propagation delay 60 ns
10 DRDY output Data ready output; active low
11 XTAL1/CLKIN input External clock input or external crystal connection; 0.1 to 8 MHz for crystal operation
12 XTAL2 input External crystal connection or no connection
13 BYPASS passive Core voltage bypass capacitor connection
14 DGND power_in Digital ground reference
15 DVDD power_in Digital power supply; range 2.7V to 5.25V
16 REFOUT output Positive reference voltage output; 2.5V
17 VREFP input Positive reference input; internal 2.5V reference or external reference
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; +5V or ±2.5V configuration
