MAX5100 满摆幅电压输出，+2.7V至+5.5V、低功

MAX5100 满摆幅电压输出，+2.7V至+5.5V、低功耗、四路、并行8位DAC

The MAX5100 parallel-input, voltage-output, quad 8-bit digital-to-analog converter (DAC) operates from a single +2.7V to +5.5V supply and comes in a space-saving 20-pin TSSOP package. Internal precision buffers swing Rail-to-Rail, and the reference input range includes both ground and the positive rail. All four DACs share a common reference input.

The MAX5100 provides double-buffered logic inputs: four 8-bit buffer registers followed by four 8-bit DAC registers. This keeps the DAC outputs from changing during the write operation. An asynchronous control pin, active-low LDAC , allows for simultaneous updating of the DAC registers. The MAX5100 features a shutdown mode that reduces current to 1nA, as well as a power-on reset mode that resets all registers to code 00 hex on power-up.
