MAX525 Datasheet | Maxim Integrated

Description The MAX525 bines four low-power, voltage-output, 12-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 MAX525 ideal for industrial-process-control applications. Other features include software shutdown, hardware shutdown lockout, an active-low reset which 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 serial interface is patible with SPI™/QSPI™ and Microwire™. It allows the input and DAC registers to be updated independently or simultaneously with a single software mand. The DAC registers can be simultaneously updated via the 3-wire serial interface. All logic inputs are TTL/CMOS-logic patible. ______________________________Features o Four 12-Bit DACs with Configurable Output Amplifiers o +5V Single-Supply Operation o Low Supply Current: 0.85m A Normal Operation 10µA Shutdown Mode o Available in 20-Pin SSOP o Power-On Reset Clears all Registers and DACs to Zero o Capable of Recalling Last State Prior to Shutdown o SPI/QSPI and Microwire patible o Simultaneous or Independent Control of DACs via 3-Wire Serial Interface o User-Programmable Digital Output _________________Ordering Information PART MAX525ACPP MAX525BCPP MAX525ACAP MAX525BCAP TEMP.
