Complete, Dual, 12-Bit Multiplying DAC with 8-Bit Bus Interface. 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 VOUT on the MX7847. No external trims are required to achieve full 12-bit performance over the entire operating temperature range.
