AD7621ASTZ Typical application Circuitry

AD7621ASTZ

The AD7621ASTZ is a 16-bit, high speed, low power, successive approximation (SAR) ADC from Analog Devices. Here is a broad overview of possible circuit connections for the AD7621ASTZ. Remember that your specific application might require different connections.

1. Power Supply: The AD7621ASTZ requires a dual supply operation. Connect +5V to the VDD pin and -5V to the VSS pin. The power supply should be properly decoupled with 10uF tantalum capacitors in parallel with 0.1uF capacitors near the package.

2. Analog Input: The VIN pin is used for analog input. The signal can range between the VSS and VDD voltage levels. You might need to include a voltage buffer or amplifier here, depending on your application.

3. Digital Outputs: The AD7621ASTZ has 16 digital output pins (DB15 to DB0) that will output the converted analog input in a digital format.

4. Control Pins: The conversion process is controlled by the CNVST pin. When CNVST goes from low to high, the ADC captures the analog input value. When CNVST goes from high to low, the ADC starts the conversion process and outputs the result on the digital output pins.

5. Clock Input: To synchronize the digital output data, utilize the SCLK pin. On the SCLK's descending edge, data is read.

6. Chip Select: The CS pin is used to enable the AD7621ASTZ. The ADC is activated when CS is low. When CS is high, the ADC is disabled and the digital output pins go into a high impedance state.

7. Data Read: The digital output data is read via the RD pin. When RD is low, data is output on the digital output pins. When RD is high, the digital output pins go into a high impedance state.

8. Ground: Each and every GND pin should be connected to the circuit's ground.

The AD7621ASTZ circuit connection is explained in general here. Always refer to the data sheet of the AD7621ASTZ for more detailed information, and always consider the specific requirements of your application when designing your circuit.
