ADS1259BIPWR

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

ADS1259BIPWR 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; reset is active low and the pin is held low for power-down.
4 START input Start conversions, active high.
5 SYNCOUT output Sync clock output (fCLK/8).
6 CS input SPI chip-select, active low; CS can be tied low.
7 SCLK input SPI clock input.
8 DIN input SPI data input.
9 DOUT output SPI data output.
10 DRDY output Data ready output, active low.
11 XTAL1/CLKIN input External clock input when using an external clock; connect to DGND when using the internal oscillator, or to an external crystal when using the crystal oscillator.
12 XTAL2 passive External crystal connection, otherwise no connection.
13 BYPASS passive Core voltage bypass.
14 DGND power_in Digital ground.
15 DVDD power_in Digital power supply; DVDD range is 2.7V to 5.25V.
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; AVSS range is -2.6V to 0V.
20 AVDD power_in Positive analog power supply; AVDD is AVSS + 4.75V to AVSS + 5.25V.
