The Maxim MX7537/MX7547 contain two 12-bit current-output multiplying digital-to-analog converters (DAC) in a single package. Input level shifters, data registers and control logic make microprocessor interfacing straight forward. Operation is from a single +12V to +15V power supply maintaining TTL, 74HC and 5V CMOS logic compatibility. The MX7547 accepts active-low CSA, active-low CSB, active-low 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, active-low CS, active-low WR and UPD signals provide full control for DAC selection and data loading.
Each of the DACs 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 difference voltage. Since both DACs are on a single monolithic chip, matching and temperature tracking between them is excellent. Gain error is specified at less than ±1 LSB, and 12-bit linearity and monotonicity are guaranteed over the full operating temperature ranges. Maxim's MX7537 and MX7547 are available in narrow 24-lead 0.3" DIP and Wide SO, as well as, 28-pin-lead PLCC packages.
