Overview
19-1559; Rev 0; 10/99 Low-Power, 12-Bit Voltage-Output DAC with Serial Interface __________________General Description The MAX5302 combines a low-power, voltage-output, 12-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 MAX5302 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/CMOSlogic compatible and buffered with Schmitt triggers to allow direct interfacing to optocouplers.
