AD7091R-4BRUZ Typical application Circuitry

AD7091R-4BRUZ

The AD7091R-4BRUZ is a 4-channel, 12-bit plus sign SAR (Successive Approximation Register) ADC (Analog to Digital Converter) from Analog Devices. This chip comes in a 20-lead TS SOP package. Here is a thorough instruction on how to connect it:

1. Supply Pins: Connect the 2.7-5.25V power supply to the VDD pin (pin 20) and ground to the GND pin (pin 10).

2. Reference Voltage: The reference voltage (REF, pin 19) determines the range of the ADC. It can be tied to VDD for the full-scale range or to a lower voltage for a smaller range. Ensure to add a decoupling capacitor (typically 0.1µF) between REF and GND.

3. Input Channels: Connect your analog input signals to the VIN0 to VIN3 pins (pins 11 to 14). These pins are the input channels of the ADC.

4. Control Pins: Connect the CS (Chip Select, pin 17), SILK (Serial Clock, pin 18), and DATA (Serial Data, pin 16) to your microcontroller or other digital logic device. These pins are used to control the AD7091R-4BRUZ and read the digital output.

5. Conversion Start Pin: The CONVST pin (pin 15) starts a conversion when driven low. Connect this to your microcontroller or to a suitable timing source.

6. GND SENSE Pin: Pin 9 is the GND_SENSE pin. Connect this pin to the system analog ground plane.

7. Alert Pin: The ALERT/RAY pin (pin 8) can serve as an interrupt to the controller, indicating data is ready.

8. Address Pins: The AD0 and AD1 pins (pins 6 and 7) are address pins. You can use these pins to set different I2C addresses if you use multiple AD7091R-4BRUZ devices on the same I2C bus.

Remember, as you integrate the AD7091R-4BRUZ with a high-side driver like VND5E004A30TR-E or any other microcontroller, always ensure that the interface voltage levels are compatible.
