General Description

The MAX5258/MAX5259 are +3V/+5V single-supply, digital serial-input, voltage-output, 8-bit octal digital-to analog converters (DACs). Internal precision buffers swing Rail-to-Rail®, and the reference input range extends from ground to the positive supply. The +5V (MAX5258) and the +3V (MAX5259) feature a 10µA (max) shutdown mode.
