Maxim Integrated MX7547KCWG

Description
The Maxim MX7537/MX7547 are dual 12-bit multiplying digital-to-analog converters (DACs) in a single package. They feature input level shifters, data registers, and control logic for easy microprocessor interfacing. The devices operate from a single 12V to 15V power supply and maintain TTL, 74HC, and 5V CMOS logic compatibility.
The MX7547 accepts CSA, CSB, WR control signals and 12 data inputs for DAC selection and full parallel data loading. The MX7537 receives data in 2 bytes, using a right-justified 8 4 format. A0, A1, CS, WR, and UPD signals provide full control for DAC selection and data loading.
Each DAC in the MX7537/MX7547 provides 4-quadrant multiplication capabilities and separate reference input and feedback resistor pins. The MX7537 additionally makes available separate AGND pins for applications where each DAC is biased at a different voltage. Since both DACs are on a single monolithic chip, matching and temperature tracking between them are excellent. Gain error is specified at less than ±1 LSB, and 12-bit linearity and monotonicity are guaranteed over the full operating temperature ranges.
