3 Description

The DACx760 are 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 are

programmable 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 one data register.

These devices include a power-on-reset function for

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 zero-scale 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 operate with either a single 10-V to 36-V

supply, or dual supplies of up to ±18 V.
