General Description

The MAX5522–MAX5525 are dual, 10-bit, ultra-low power, voltage-output, digital-to-analog converters (DACs) offering rail-to-rail buffered voltage outputs. The DACs operate from a 1.8V to 5.5V supply and consume less than 5µA, making the devices suitable for low power and low-voltage applications. A shutdown mode reduces overall current, including the reference input current, to just 0.18µA. The MAX5522–MAX5525 use a 3-wire serial interface that is compatible with SPI™, QSPI™, and MICROWIRE™.
