10-Bit Voltage-Output DAC
in 8-Pin µMAX
General Description
Features
The MAX5304 combines a low-power, voltage-output,
10-bit digital-to-analog converter (DAC) and a precision
output amplifier in an 8-pin µMAX package. It operates
from a single +5V supply, drawing less than 280µA of
supply current.
ꢀ 10-Bit DAC with Configurable Output Amplifier
ꢀ +5V Single-Supply Operation
ꢀ Low Supply Current
0.28mA Normal Operation
2µA Shutdown Mode
The output amplifier’s inverting input is available to the
user, allowing specific gain configurations, remote
sensing, and high output-current capability. This makes
the MAX5304 ideal for a wide range of applications,
including industrial process control. Other features
include a software shutdown and power-on reset.
ꢀ Available in 8-Pin µMAX
ꢀ Power-On Reset Clears DAC Output to Zero
ꢀ SPI/QSPI/MICROWIRE Compatible
ꢀ Schmitt-Trigger Digital Inputs for Direct
The serial interface is SPI™/QSPI™/MICROWIRE™
compatible. 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
are TTL/CMOS-logic compatible and buffered with
Schmitt triggers to allow direct interfacing to optocou-
plers.
