ADS7254IRTER

Texas Instruments · Analog To Digital Converters (ADC) · WQFN-16-EP(3x3)

ADS7254IRTER from Texas Instruments, in a WQFN-16-EP(3x3). 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 REFIO_A bidirectional Reference voltage input/output for channel A, which the datasheet describes as a buffered 2.5 V internal reference that can be programmed through REFDAC_A.
2 REFGND_A power_in Reference ground potential for channel A; REFGND_x must stay within 0.3 V of GND.
3 REFGND_B power_in Reference ground potential for channel B; REFGND_x must stay within 0.3 V of GND.
4 REFIO_B bidirectional Reference voltage input/output for channel B, which the datasheet describes as a buffered 2.5 V internal reference that can be programmed through REFDAC_B.
5 AINM_B input Negative analog input for channel B; analog inputs are limited to REFGND_x - 0.3 V to AVDD + 0.3 V.
6 AINP_B input Positive analog input for channel B; analog inputs are limited to REFGND_x - 0.3 V to AVDD + 0.3 V.
7 DVDD power_in Digital I/O supply, 3.3 V nominal per the recommended operating conditions; AVDD to REFGND_x or DVDD to GND is rated -0.3 V to 6 V.
8 SDI input Data input for the serial interface; digital inputs are limited to GND - 0.3 V to DVDD + 0.3 V.
9 CS input Active-low chip-select for the serial interface; a CS falling edge brings the serial data bus out of 3-state.
10 SCLK input Serial communication clock input that drives conversions and data transfer in the selected interface mode.
11 SDO_A output Serial data output for channel A (and channel B in single-SDO mode); the pin is 3-stated when CS is high.
12 SDO_B output Serial data output for channel B; the pin is 3-stated when CS is high and outputs 0s in the 32-CLK dual-SDO readback frame.
13 GND power_in Digital ground for the device.
14 AVDD power_in Analog supply for ADC operation, 5 V nominal per the recommended operating conditions; AVDD to REFGND_x is rated -0.3 V to 6 V.
15 AINP_A input Positive analog input for channel A; analog inputs are limited to REFGND_x - 0.3 V to AVDD + 0.3 V.
16 AINM_A input Negative analog input for channel A; analog inputs are limited to REFGND_x - 0.3 V to AVDD + 0.3 V.
17 Thermal Pad passive Exposed pad (from the footprint; not named in the datasheet pin table).
