The digital I/O may be used to configure the device, acquire data, control peripherals, or control the bias of on-chip operational amplifiers.

Working Principle

The operation of this digital-to-analog converter is based on the successive approximation concept. This means that it measures the analog output of each digital input and compares it to a reference voltage or current level. In each successive step, the digital input is adjusted until the analog output is equal to the reference voltage or current. The final digital output is the code that corresponds to the closest match. The MAX5480AEEE+ is capable of converting a single-ended or differential digital input from 4–16 bits into a voltage or current output.

This device is ideal for applications that require low power consumption, low noise and low cost. It features a low power consumption of 1.6 mW, low amplitude noise of just 100 nV/rtHz, and a low applied voltage of 1.6V. The device also features a fast conversion time of 1.3 µs/step and low offset and gain errors.

The MAX5480AEEE+ includes on-chip high-voltage and low-voltage reference options, allowing it to be used with a wide range of power supply voltages. The device also includes a buffered voltage output buffer and a fast current output buffer to meet the most stringent accuracy requirements. The device is available in a 24-lead TSSOP and a 28-lead QFN package.
