2.7V to +5.5V, Low-Power, Dual, Parallel 8-Bit DAC with Rail-to-Rail Voltage Outputs

The MAX5102 parallel-input, voltage-output, dual 8-bit digital-to-analog converter (DAC) operates from a single +2.7V to +5.5V supply and comes in a space-saving 16-pin TSSOP package. Internal precision buffers swing rail-to-rail, and the reference input range includes both ground and the positive rail. Both DACs share a common reference input.

The MAX5102 has separate input latches for each of its DACs. Data is transferred to the input latches from a common 8-bit input port. The DACs are individually selected through address input A0 and are updated by bringing active-low WR low.

The MAX5102 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.
