MAX5251 Datasheet | Maxim Integrated

Description The +3V MAX5251 bines four low-power, voltageoutput, 10-bit digital-to-analog converters (DACs) and four precision output amplifiers in a space-saving, 20pin 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 MAX5251 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 patible with SPI™/QSPI™ and Microwire™. It allows the input and DAC registers to be updated independently or simultaneously with a single software mand. All logic inputs are TTL/CMOSlogic patible. ______________________________Features o Four 10-Bit DACs with Configurable Output Amplifiers o +3.0V to +3.6V Single-Supply Operation o Low Supply Current: 0.8m A Normal Operation 3µA Shutdown Mode o Available in 20-Pin SSOP o Power-On Reset Clears all Registers and DACs to Zero o SPI/QSPI and Microwire patible o Simultaneous or Independent Control of DACs via 3-Wire Serial Interface o User-Programmable Digital Output o Schmitt-Trigger Digital Inputs for Direct Optocoupler Interface o 12-Bit Upgrade Available: MAX5253 _________________Ordering Information PART TEMP.
