    AD5421BREZ Typical application Circuitry Schematics

    AD5421BREZ

    The AD5421BREZ is a loop-powered, 4-20mA, 16-bit DAC (Digital-to-Analog Converter) from Analog Devices, commonly found in process control applications, including industrial automation and instrumentation. Here is a simplified illustration of how you could add this part to an application circuit: 

    1. Power Supply: Connect AVDD to a +3.3V to +5.25V source and AVSS to the system ground. 
    2. Loop Supply and Output: The AD5421BREZ is a loop-powered device, meaning that it gets its power from the 4-20mA current loop in which it operates. Connect the VLOOP pin to a loop supply voltage (typically 24V), and the IOUT pin to your load, which could be a resistor or a process control input. 
    3. Digital Inputs: Through a serial interface, the AD5421BREZ DAC interfaces with a microcontroller. The SCLK (serial clock) and DIN (data input) pins should be connected to corresponding outputs on the microcontroller. The /SYNC pin should also be connected to the microcontroller to control data synchronization. 
    4. Fault and Alarm: The AD5421BREZ FAULT pin can be used to indicate an alarm condition, such as an open loop or overtemperature situation. This pin can be monitored by the microcontroller to detect and handle these conditions. 
    5. Clear: The CLR pin, when driven high, will clear the input and DAC registers, resetting the current output to the programmed 4mA state. 
    6. Sense and Compliance: The AD5421BREZ AD5421 includes a compliance voltage output (VCOM) and a sense input (ISENSE). These can be connected to the system to monitor the loop voltage and to compensate for any voltage drop across the loop supply wires. 
    Remember that the specific application of the AD5421BREZ might require additional components and considerations like decoupling capacitors, watchdog timers, and protection circuits. Always refer to the datasheet and other documentation from the manufacturer for complete details and guidelines.
