DAC8760IPWPR

The DAC7760 and DAC8760 are low-cost, precision, fully-integrated, 12-bit and 16-bit digital-to-analog converters (DACs) designed to meet the requirements of industrial process-control applications. These devices can be programmed as a current output with a range of 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA; or as a voltage output 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 to 11 V, ±5.5 V, or ±11 V). Both current and voltage outputs can be simultaneously enabled while being 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 voltage outputs to zeroscale or midscale, and the current output to the low end of the range, if the output is enabled. Zero and gain registers can be programmed to digitally calibrate the device in the end system. The output slew rate is also programmable by register. These devices can superimpose an external HART signal on the current output and can operate with either a single +10 V to +36 V supply, or dual supplies of up to ±18 V. All versions are available in both 6-mm×6-mm QFN-40 and TSSOP-24 packages.
