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.
