ADS8354IRTER 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; the analog and reference input voltage must stay between -0.3 V and AVDD + 0.3 V with respect to REFGND_A. |
| 2 | REFGND_A | power_in | Reference ground potential for channel A; the ground voltage difference |
| 3 | REFGND_B | power_in | Reference ground potential for channel B; the ground voltage difference |
| 4 | REFIO_B | bidirectional | Reference voltage input/output for channel B; the analog and reference input voltage must stay between -0.3 V and AVDD + 0.3 V with respect to REFGND_B. |
| 5 | AINM_B | input | Negative analog input for channel B; the voltage must stay between -0.3 V and AVDD + 0.3 V with respect to REFGND_B. |
| 6 | AINP_B | input | Positive analog input for channel B; the voltage must stay between -0.3 V and AVDD + 0.3 V with respect to REFGND_B. |
| 7 | DVDD | power_in | Digital I/O supply; recommended 3.3 V nominal, and DVDD to GND is limited to -0.3 V to 6 V. |
| 8 | SDI | input | Serial data input; digital input voltage must stay between GND - 0.3 V and DVDD + 0.3 V. |
| 9 | CS | input | Active-low chip-select signal; digital input voltage must stay between GND - 0.3 V and DVDD + 0.3 V. |
| 10 | SCLK | input | Clock for serial communication; digital input voltage must stay between GND - 0.3 V and DVDD + 0.3 V. |
| 11 | SDO_A | output | Serial data output for channel A (and channel B in single-SDO mode); it is in 3-state when CS is high. |
| 12 | SDO_B | output | Serial data output for channel B; it outputs 0s in the register readback frame and stays in 3-state in single-SDO mode, where it can be treated as no connect. |
| 13 | GND | power_in | Digital ground; the digital input voltage is referenced to this pin. |
| 14 | AVDD | power_in | Supply voltage for ADC operation; recommended 5 V nominal, and AVDD to REFGND_x is limited to -0.3 V to 6 V. |
| 15 | AINP_A | input | Positive analog input for channel A; the voltage must stay between -0.3 V and AVDD + 0.3 V with respect to REFGND_A. |
| 16 | AINM_A | input | Negative analog input for channel A; the voltage must stay between -0.3 V and AVDD + 0.3 V with respect to REFGND_A. |
| 17 | Thermal Pad | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
