**Texas Instruments** · Analog To Digital Converters (ADC) · TSSOP-16

ADS7254IPWR from Texas Instruments, in a TSSOP-16. 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_A | input | Positive analog input for channel A; fully-differential input with absolute maximum range of -0.3 V to AVDD + 0.3 V with respect to REFGND_A. |
| 2 | AINM_A | input | Negative analog input for channel A; absolute maximum range of -0.3 V to AVDD + 0.3 V with respect to REFGND_A. |
| 3 | REFIO_A | bidirectional | Reference voltage input/output for channel A, referenced to REFGND_A; absolute maximum range of -0.3 V to AVDD + 0.3 V. |
| 4 | REFGND_A | power_in | Reference ground potential for channel A; ground difference |REFGND_x - GND| must not exceed 0.3 V. |
| 5 | REFGND_B | power_in | Reference ground potential for channel B; ground difference |REFGND_x - GND| must not exceed 0.3 V. |
| 6 | REFIO_B | bidirectional | Reference voltage input/output for channel B, referenced to REFGND_B; absolute maximum range of -0.3 V to AVDD + 0.3 V. |
| 7 | AINM_B | input | Negative analog input for channel B; absolute maximum range of -0.3 V to AVDD + 0.3 V with respect to REFGND_B. |
| 8 | AINP_B | input | Positive analog input for channel B; fully-differential input with absolute maximum range of -0.3 V to AVDD + 0.3 V with respect to REFGND_B. |
| 9 | DVDD | power_in | Digital I/O supply; recommended operating voltage 3.3 V, absolute maximum 6 V with respect to GND. |
| 10 | SDI | input | Data input for the serial communication interface; digital input voltage limited to GND - 0.3 V to DVDD + 0.3 V. |
| 11 | CS | input | Chip-select signal, active low; digital input voltage limited to GND - 0.3 V to DVDD + 0.3 V. |
| 12 | SCLK | input | Clock for serial communication; digital input voltage limited to GND - 0.3 V to DVDD + 0.3 V. |
| 13 | SDO_A | output | Data output for serial communication, carrying channel A and channel B conversion data depending on interface mode. |
| 14 | SDO_B | output | Data output for serial communication, channel B; remains in 3-state in single-SDO mode and can be treated as no connect. |
| 15 | GND | power_in | Digital ground; reference for digital input voltage limits. |
| 16 | AVDD | power_in | Analog supply voltage for ADC operation; recommended operating voltage 5 V, absolute maximum 6 V with respect to REFGND_x. |
