Low-Power, Dual, 13-Bit Voltage-Output DACs
_______________General Description
The MAX5150/MAX5151 low-power, serial, voltage-out-
put, dual 13-bit digital-to-analog converters (DACs)
consume only 500µA from a single +5V (MAX5150) or
+3V (MAX5151) supply. These devices feature Rail-to-
®
Rail
output swing and are available in a space-saving
16-pin QSOP package. To maximize the dynamic
range, the DAC output amplifiers are configured with an
internal gain of +2.
The 3-wire serial interface is SPI™/QSPI™ and
Microwire™ compatible. Each DAC has a double-
buffered input organized as an input register followed
by a DAC register, which allows the input and DAC reg-
isters to be updated independently or simultaneously
with a 16-bit serial word. Additional features include
programmable shutdown (2µA), hardware-shutdown
lockout, a separate reference voltage input for each
DAC that accepts AC and DC signals, and an active-
low clear input (CL) that resets all registers and DACs
to zero. These devices provide a programmable logic
pin for added functionality, and a serial-data output pin
for daisy-chaining.
