♦ 13-Bit Dual DAC with Internal Gain of +2
♦ Rail-to-Rail Output Swing
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-p in QSOP p a c ka g e . To ma ximize the d yna mic
range, the DAC output amplifiers are configured with an
internal gain of +2.
♦ 16µs Settling Time
♦ Single-Supply Operation: +5V (MAX5150)
+3V (MAX5151)
♦ Low Quiescent Current: 500µA (normal operation)
2µA (shutdown mode)
The 3-wire s e ria l inte rfa c e is SPI™/QSPI™ a nd
Mic rowire ™ c omp a tib le . Ea c h DAC ha s a d oub le -
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.
♦ SPI/QSPI and Microwire Compatible
♦ Available in Space-Saving 16-Pin QSOP Package
♦ Power-On Reset Clears Registers and DACs
to Zero
♦ Adjustable Output Offset
