AD7792BRUZ Pin Function Description (16-Pin LFCSP Package)
Pin Number Pin Name Pin Function Description 1 VDD This is the positive supply voltage pin. It provides the necessary power for the device's operation. The voltage applied to this pin should be in the range of 2.7V to 5.25V. 2 AGND Analog ground reference pin. It is the reference for all analog signals within the device. It should be connected to the system ground. 3 SCLK Serial clock input pin. This pin receives the clock signal used to synchronize data transfer to and from the AD7792. The clock should be in the range of 0Hz to 10MHz, depending on the configuration. 4 SDIN Serial data input pin. This is used to transmit serial data into the device. It is used when sending commands or configuration data to the AD7792. 5 SDOUT Serial data output pin. This pin outputs data from the AD7792 to a microcontroller or other device. It is used for reading back data from the ADC. 6 CS Chip Select pin. This pin is used to select the AD7792 device for communication over the SPI interface . It is active low, meaning the device is selected when this pin is pulled low. 7 AIN1 Analog input channel 1. This is one of the differential input pins that connect to the sensor or analog signal source. AIN1 pairs with AIN2 to form a differential input. 8 AIN2 Analog input channel 2. This is the second pin of the differential input, used in combination with AIN1 for input signals. 9 REFIN+ Reference input pin (positive). This pin is used to provide the positive reference voltage for the analog-to-digital conversion. The reference voltage can be applied here relative to REFIN-. 10 REFIN- Reference input pin (negative). This is the negative reference pin for the ADC. The difference between REFIN+ and REFIN- determines the input range for conversion. 11 VOUT Output voltage reference pin. This pin can be used to output a reference voltage to the system, which can be helpful in some applications requiring a stable voltage reference for other components. 12 AVDD Analog power supply pin. This pin powers the analog circuitry inside the AD7792. It should be connected to a stable voltage supply. 13 AGND Analog ground pin. A reference for all the analog signals within the IC. The external analog ground should be connected here. 14 DOUT Digital output. This pin transmits digital data out of the AD7792 in SPI communication mode. 15 CALIBRATION Calibration pin. This pin is used to apply a specific calibration signal to adjust the offset and gain of the ADC. 16 RESET Reset pin. This pin is used to reset the AD7792 device. When this pin is asserted low, the device is reset to its default state, and all configuration registers are returned to their default values.20 Common FAQs for the AD7792BRUZ
