General Description
The MAX5101 parallel-input, voltage-output, triple 8-bit
digital-to-analog converter (DAC) operates from a sin-
gle +2.7V to +5.5V supply and comes in a space-sav-
ing 16-pin TSSOP package. Internal precision buffers
swing Rail-to-Rail
® . For all three DACs, the internal ref-
erence voltage is tied to V DD .
The MAX5101 has separate input latches for each of its
three DACs. Data is transferred to the input latches
from a common 8-bit input port. The DACs are individu-
ally selected through address inputs A0 and A1 and
are updated by bringing WR low.
The MAX5101 features a 1µA software shutdown mode,
as well as a power-on reset mode that resets all regis-
ters to code 00 hex on power-up.
