Working Principles of AD5373BCPZ

The AD5373BCPZ is a precision voltage/current output DAC with 16-bit resolution, maximum voltage/current outputs of 250 mV/25 mA, and low power consumption. The resolution of the device is determined by the reference voltage, which is supplied externally. The external reference voltage determines the full-scale portion of the input range to which the 16-bit input code is proportionally divided.The AD5373BCPZ has an input register with SPI/QSPI control. This allows data values to be transferred via a 4-wire interface. The input register is 16 bits in length and stores the data values sent via the interface. The stored values are converted to an analog voltage or current output.In voltage output mode, the voltage output buffer is internally connected to the DAC. The voltage output buffer allows the output to be connected directly to an external load with minimal loading, and provides a voltage gain of 1. In current output mode, the current output buffer is used to drive current into an external load, allowing for a gain of 1 to 10.

Conclusion

The AD5373BCPZ is a precision voltage/current output Digital to Analog Converter from Analog Devices. The device offers an excellent combination of accuracy, low power consumption, high speed, and dynamic process control. The AD5373BCPZ is suitable for a variety of applications, including data acquisition, industrial process control, test, measurement, and medical imaging. The device has 16-bit resolution and allows data values to be transferred via a 4-wire interface. The on-board output buffer and gain adjustment allow for a direct connection to an external load with minimal loading.
