ADS7924IRTET 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 | RESET | input | External reset input, active low |
| 2 | INT | output | Interrupt output pin, active low; generated when input voltage exceeds programmed threshold |
| 3 | SCLK | input | I2C serial clock input |
| 4 | SDA | bidirectional | I2C serial data line, open-drain bidirectional |
| 5 | A0 | input | I2C address selection input; ground for slave address 1001000, DVDD for 1001001 |
| 6 | DGND | power_in | Digital ground reference |
| 7 | PWRCON | output | Digital output to control shutdown/power-up of external operational amplifier |
| 8 | AGND | power_in | Analog ground reference; thermal pad also connects to AGND |
| 9 | CH3 | input | Analog input channel 3 of 4-channel multiplexer |
| 10 | CH2 | input | Analog input channel 2 of 4-channel multiplexer |
| 11 | CH1 | input | Analog input channel 1 of 4-channel multiplexer |
| 12 | CH0 | input | Analog input channel 0 of 4-channel multiplexer |
| 13 | MUXOUT | output | Multiplexer output; routes selected channel to ADC input through signal conditioning |
| 14 | ADCIN | input | Analog-to-digital converter input, connected to multiplexer output |
| 15 | AVDD | power_in | Analog power supply input, 2.2 V to 5.5 V |
| 16 | DVDD | power_in | Digital power supply input, 1.65 V to 5.5 V |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
