ADS7049QDCURQ1
Texas Instruments · Analog To Digital Converters (ADCs) · VSSOP-8
ADS7049QDCURQ1 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, specified from 1.65 V to 3.6 V and independent of AVDD. |
| 2 | SCLK | input | Serial clock used for conversion and data transfer, requiring only a 32-MHz SCLK to support 2 MSPS throughput. |
| 3 | SDO | output | Serial data output that presents two leading zeros followed by the 12-bit conversion result, and returns to tri-state when CS rises. |
| 4 | CS | input | Active-low chip-select; the input is sampled on the CS falling edge and a CS rising edge ends the frame. |
| 5 | AINM | input | Negative analog signal input, which accepts signals from -100 mV to 100 mV. |
| 6 | AINP | input | Positive analog signal input, which accepts signals from 0 V to AVDD. |
| 7 | AVDD | power_in | Analog power-supply input, specified from 2.35 V to 3.6 V, which also provides the ADC reference voltage. |
| 8 | GND | power_in | Ground for the power supply; all analog and digital signals are referred to this pin. |
