_______________General Desc ription
The MX7837/MX7847 are dual, 12-bit, multiplying, volt-
age-output digital-to-analog converters (DACs). Each
DAC has an output amplifier and a feedback resistor.
The output amplifier is capable of developing ±10V
across a 2k
load. The amplifier feedback resistor is
internally connected to V
OUT
on the MX7847. No exter-
nal trims are required to achieve full 12-bit performance
over the entire operating temperature range.
The MX7847 has a 12-bit parallel data input, whereas
the MX7837 operates with a double-buffered 8-bit-bus
interface that loads data in two write operations. All
logic signals are level triggered and are TTL and CMOS
compatible. Fast timing specifications make these
DACs compatible with most microprocessors.
