Pinout
1. Analog Inputs (VIN+): The ADC has one differential input for signal processing.
2. Digital Outputs (D0-D11): These pins output the digital representation of the analog input; D0 is the least significant bit (LSB), and D11 is the most significant bit (MSB).
3. Control Pins:
- CS (Chip Select): Used to enable the device.
- SCLK (Serial Clock): Controls the timing of data transfer.
- DIN (Data Input): Used for inputting commands.
- DOUT (Data Output): Used for outputting the digital data.
4. Power Supply Pins: VDD provides power to the ADC, while GND is the ground reference.
5. Reference Input (VREF): Sets the reference voltage for conversion.
The AD7091R-5BRUZ is designed for high-performance applications requiring precise analog-to-digital conversion.
