Working Principle and Block Diagram

The AD5691RBCPZ-RL7 is a current-output, 12-bit digital-to-analog converter using a 2.5V to 5.5V supply. It has a temperature range of -40°C to +125°C. It features low power consumption, a power-down mode, a wide operating voltage range, and low jitter digital data interface with phase-lock loop (PLL) synchronization. The AD5691RBCPZ-RL7 accepts digital inputs in either binary or two\'s complement format, then converts them to an analog output voltage. The converter operates on an integrated voltage reference, analog output amplifier, and internal reference buffer. Its input is expressed in 12 bits and a 3 V logic level. The DAC output current is converted to voltage by an external resistor.

The block diagram of the AD5691RBCPZ-RL7 is shown below. It contains a reference buffer, DAC core, and an output amplifier. The reference buffer provides stable reference voltage to the DAC core. The DAC Core receives the digital input and generates a corresponding analog voltage or current output. The output amplifier then converts the current output of the DAC core to a voltage output. The PLL Synchronization block provides the timing for the digital inputs.
