Working Principle:

The AD7534JP is a 16-bit, high-performance digital-to-analog converter (DAC) that operates on a single 3.3V supply. It is a part of a general purpose digital-to-analog converter (DAC) family of devices. The main digital interface is a 16-bit parallel port with clock and control inputs. The device features 256x oversampling rate and each digital output code is clocked out. The AD7534JP also features an auto-zeroing function to provide low offset and gain error.

The device has two components; a resistive ladder network and a buffer amplifier. The resistive ladder network provides the actual DAC outputs. This ladder network is made up of resistors connected in parallel. As the binary data bits arrive at the DAC inputs, the resistances of the ladder elements are varied accordingly. These varying resistance values are then converted into analog voltage values at the output of the device.

The buffer amplifier is used to provide high output drive currents and low output-voltage noise. It consists of an operational amplifier, a voltage follower and a summing amplifier. The operational amplifier drives the output voltage to a desired level, while the voltage follower amplifies the output of the operational amplifier. The summing amplifier takes the output of the voltage follower and combines it with the digital voltage output of the resistive ladder to provide the analog output voltage.
