# ADS7029QDCURQ1

**Texas Instruments** · Analog To Digital Converters (ADC) · VSSOP-8

ADS7029QDCURQ1 from Texas Instruments, in a VSSOP-8. 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 | DVDD | power_in | Digital I/O supply voltage, 1.65V to 3.6V independent of AVDD |
| 2 | SCLK | input | Serial clock input, maximum 24MHz for 2MSPS throughput operation |
| 3 | SDO | output | Serial data output providing ADC conversion results in straight binary format |
| 4 | CS | input | Chip-select signal active low, defines one conversion and serial transfer frame |
| 5 | AINM | input | Analog signal input negative, accepts signals from -100mV to 100mV |
| 6 | AINP | input | Analog signal input positive, accepts signals from 0V to AVDD |
| 7 | AVDD | power_in | Analog power supply voltage 2.35V to 3.6V, serves as ADC reference voltage |
| 8 | GND | power_in | Ground reference for power supply and all analog and digital signals |
