TI DAC8760EMC-EVM

Overview

The DAC7760 andDAC8760EMC-EVM are low-cost, precision,fully-integrated, 12-bit and 16-bit digital-to-analog converters (DACs) designed to meet therequirements of industrial process-control applications. These devices can be programmed as acurrent output with a range of 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA; or as a voltageoutput with a range of 0 V to 5 V, 0 V to 10 V, ±5 V, or±10 V with a 10% overrange (0 V to 5.5 V, 0 V to11 V, ±5.5 V, or ±11 V). Both current and voltage outputs can be simultaneously enabled whilebeing controlled by a single data register.

These devices include a power-on-reset function to ensure powering up in a known state(both IOUT and VOUT are disabled and in a Hi-Z state). The CLR and CLR-SEL pins set the voltageoutputs to zero-scale or midscale, and the current output to the low end of the range, if theoutput is enabled. Zero and gain registers can be programmed to digitally calibrate the device inthe end system. The output slew rate is also programmable by register. These devices cansuperimpose an external HART signal on the current output and can operate with either a single10-V to 36-V supply, or dual supplies of up to ±18 V. All versions are available in both 6-mm ×6-mm 40-pin VQFN and 24-pin HTSSOP packages.
