General Description
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 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.
