Overview
19-1562; Rev 0; 10/99 10-Bit Voltage-Output DAC in 8-Pin µMAX General Description 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.
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.
The serial interface is SPI™/QSPI™/MICROWIRE™ compatible.
The DAC has a double-buffered input, organized as an input register followed by a DAC register.
A 16-bit serial word loads data into the input register.
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 optocouplers.
