Description

General part information

MX7837 Series

The MX7837/MX7847 are dual, 12-bit, multiplying, voltage-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 2kΩ load. The amplifier feedback resistor is internally connected to VOUTon the MX7847. No external 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.ApplicationsDigital Gain and Offset ControlIndustrial Process ControlsMachine- and Motion-Control Systems
