The Maxim MX7538 is a high performance monolithic 14-bit multiplying digital-to-analog converter (DAC). It operates with a 14-bit data bus using standard chip select and memory write logic, optimized for unipolar applications but capable of bipolar operation with additional external components. Full accuracy is maintained over the operating temperature range through wafer-level laser-trimmed thin-film resistors and temperature compensated NMOS switches.
The device features quadrant multiplication, uP compatible double buffered inputs, low power consumption, and TTL, 74HC, and 5V CMOS compatibility. It is available in narrow (0.3") 24-lead DIP and Wide SO packages.
