描述

The +5V MAX5250 combines four low-power, voltage-output, 10-bit digital-to-analog converters (DACs) and four precision output amplifiers in a space-saving, 20-pin package. In addition to the four voltage outputs, each amplifier's negative input is also available to the user. This facilitates specific gain configurations, remote sensing, and high output drive capacity, making the MAX5250 ideal for industrial-process-control applications. Other features include software shutdown, hardware shutdown lockout, an active-low reset that clears all registers and DACs to zero, a user-programmable logic output, and a serial-data output.

Each DAC has a double-buffered input organized as an input register followed by a DAC register. A 16-bit serial word loads data into each input/DAC register. The 3-wire serial interface is compatible with SPI™/QSPI™ and Microwire™. It allows the input and DAC registers to be updated independently or simultaneously with a single software command. All logic inputs are TTL/CMOS-logic compatible.
