DESCRIPTION
The DAC4815 is one in a family of dual and quad
12-bit digital-to-analog converters (DACs). Serial,
8-bit, 12-bit interfaces are available.
The DAC4815 is complete. It contains CMOS logic,
switches, a high-performance buried-zener reference,
and low-noise bipolar output amplifiers. No external
8-Bit
Port and
Logic
components are required for bipolar ±10V output ^{Control In}
range.
The DAC4815 has a 2-byte (8 + 4) double-buffered
interface. Data is first loaded (level transferred) into
the input registers in two steps for each DAC. Then
both DACs are updated simultaneously. The DAC has
an asynchronous clear control for reset to bipolar zero.
This feature is useful for power-on reset or system
calibration. The DAC4815 is packaged in a 28-pin
plastic DIP rated for the –40°C to +85°C extended
industrial temperature range.
High-stability laser-trimmed thin film resistors assure
high reliability and true 12-bit integral and differential
linearity over the full specified temperature range.
