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). |
