FEATURES

GENERAL DESCRIPTION

The DAC-HZ Series are high-performance, monolithic, 12-bit

binary and 3-digit BCD, digital-to-analog converters. The

DAC-HZ Series are complete and self-contained with a

precision internal reference and fast output operational

amplifier. Pin programmable output voltage and current

ranges are provided for a high degree of application flexibility;

the binary versions offer 5 output voltage ranges and two

current ranges while the BCD models offer 3 and 1 output

ranges, respectively.

The DAC-HZ Series contains a precision embedded Zener

reference circuit. This eliminates code-dependent ground

currents by routing current from the positive supply to the

internal ground node as determined by the R-2R ladder

network. The internal feedback resistors for the on-board

amplifier track the ladder network resistors, enhancing

temperature performance. The excellent tracking of the

resistors results in temperature coefficients for differential

nonlinearity, zero and gain of ±2, ±3 and ±20ppm/°C

maximum, respectively.
