+2.7V to +5.5V, Low-Power, Quad, Parallel
8-Bit DAC with Rail-to-Rail Voltage Outputs
General Description
The MAX5100 parallel-input, voltage-output, quad 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 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, 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.
