The MAX5354/MAX5355 combine a low-power, voltage-
output, 10-bit digital-to-analog converter (DAC) and a
precision output amplifier in an 8-pin µMAX or DIP pack-
age. The MAX5354 operates from a single +5V supply,
and the MAX5355 operates from a single +3.3V supply.
Both devices draw less than 280µA of supply current.
♦ 10-Bit DAC with Configurable Output Amplifier
♦ +5V Single-Supply Operation (MAX5354)
+3.3V Single-Supply Operation (MAX5355)
♦ Low Supply Current: 0.28mA Normal Operation
2µA Shutdown Mode
The output amplifier’s inverting input is available to the
us e r, a llowing s p e c ific g a in c onfig ura tions , re mote
sensing, and high output current capability. This makes
the MAX5354/MAX5355 ideal for a wide range of appli-
cations, including industrial process control. Other fea-
tures include a software shutdown and power-on reset.
♦ Available in 8-Pin µMAX
♦ Power-On Reset Clears DAC Output to Zero
♦ SPI/QSPI and Microwire Compatible
♦ Schmitt-Trigger Digital Inputs for Direct
Optocoupler Interface
The serial interface is compatible with SPI™/QSPI™
and Microwire™. The DAC has a double-buffered input,
organized as an input register followed by a DAC regis-
ter. A 16-bit serial word loads data into the input regis-
ter. The DAC register can be updated independently or
simultaneously with the input register. All logic inputs
a re TTL/CMOS-log ic c omp a tib le a nd b uffe re d with
Schmitt triggers to allow direct interfacing to opto-
couplers.
♦ +3.3V MAX5355 Directly Interfaces with +5V Logic
