The MAX5180 contains two 10-bit, simultaneousupdate, current-output digital-to-analog converters (DACs) designed for superior performance in communications systems requiring analog signal reconstruction with low distortion and low-power operation. The MAX5183 provides equal specifications, with on-chip precision resistors for voltage output operation. The devices are designed for 10pVs glitch operation to minimize unwanted spurious signal components at the output. An on-board 1.2V bandgap circuit provides a well-regulated, low-noise reference that can be disabled for external reference operation. The MAX5180/MAX5183 are designed to provide a high level of signal integrity for the least amount of power dissipation. The DACs operate from a single supply of 2.7V to 3.3V. Additionally, these DACs have three modes of operation: normal, low-power standby, and complete shutdown, which provides the lowest possible power dissipation with 1A (max) shutdown current. A fast wakeup time (0.5s) from standby mode to full DAC operation conserves power by activating the DACs only when required.
