ADS7142QDQCRQ1 from Texas Instruments, in a WSON-10-EP(2x3). 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 | GND | power_in | Supply ground for the power supply; all analog and digital signals are referred to this pin. |
| 2 | AVDD | power_in | Analog supply input that is also used as the reference voltage for analog-to-digital conversion. |
| 3 | AINP/AIN0 | input | In single-channel operation this is the positive analog signal input, and in two-channel operation it is the analog signal input for channel 0. |
| 4 | AINM/AIN1 | input | In single-channel operation this is the negative analog signal input, and in two-channel operation it is the analog signal input for channel 1. |
| 5 | ADDR | input | Analog input used to select the I2C address of the device, as described in the I2C Address Selector section. |
| 6 | BUSY/RDY | output | The device drives this digital output high while scanning through channels in a sequence and drives it low when the sequence is completed or aborted. |
| 7 | ALERT | output | Active-low open-drain digital output controlled by the digital window comparator block, requiring a pullup resistor from DVDD. |
| 8 | SDA | bidirectional | Serial data input/output for the I2C interface, requiring a pullup resistor from DVDD. |
| 9 | SCL | input | Serial clock input for the I2C interface, requiring a pullup resistor from DVDD. |
| 10 | DVDD | power_in | Digital I/O supply voltage for the device. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
