# ADS7043IDCUT

**Texas Instruments** · Analog To Digital Converters (ADCs) · VSSOP-8-0.5mm

ADS7043IDCUT from Texas Instruments, in a VSSOP-8-0.5mm. 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 at 1.65 V to 3.6 V and independent of AVDD. |
| 2 | SCLK | input | Serial clock input used for both conversion and data transfer; a 16 MHz SCLK supports 1 MSPS throughput. |
| 3 | SDO | output | Serial data output that carries the conversion result, with the bus returned to 3-state when CS goes high. |
| 4 | CS | input | Active-low chip select; the CS falling edge samples the analog input and starts conversion, and the rising edge ends the frame. |
| 5 | AINM | input | Negative analog signal input for the pseudo-differential input, which the datasheet specifies to be within AVDD/2 ± 100 mV. |
| 6 | AINP | input | Positive analog signal input, which the datasheet specifies to accept signals from 0 V to AVDD. |
| 7 | AVDD | power_in | Analog power supply input specified at 1.65 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. |
