Maxim Integrated MAX5189BEEI T

Description
The MAX5186/MAX5189 are dual, 8-bit, 40MHz, current/voltage, simultaneous-output DACs designed for superior performance in communication systems requiring analog signal reconstruction with low distortion and low-power operation. They feature a 10pV-s 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 MAX5186/MAX5189 are designed to provide a high level of signal integrity for the least amount of power dissipation. They operate from a single supply voltage of 2.7V to 3.3V and have three modes of operation: normal, low-power standby, and complete shutdown, which provides the lowest possible power dissipation with a 1μA (max) shutdown current. A fast wake-up time (0.5us) from standby mode to full DAC operation allows power conservation by activating the DACs only when required.
