Analog Devices Inc./Maxim Integrated

The MX7523 is high performance multiplying 8 bit digital-to-analog converter (DAC). Low power CMOS technology and low cost make it suitable for a wide range of analog data acquisition and control applications. Thin-film resistors assure 8 bit resolution with up to 10 bit linearity (L grade) over the full operating temperature range. In addition, all digital inputs are compatible with CMOS logic level.Maxim's MX7523 is electrically and pin compatible with the Analog Devices AD7523 and is available in a standard width 16-lead DIP as well as small outline package.ApplicationsAudio Gain ControlAutomatic Test EquipmentBattery Powered InstrumentsDigital Calibration SystemsDigitally Controlled FiltersMotion Control SystemsProgrammable Power Supplies

The MX7528/MX7628 contains two 8-bit multiplying digital-to-analog converters (DACs). Separate on-chip latches hold the input data for each DAC to allow easy interface to microprocessors. The data load operation is similar to a static RAM write cycle. Data is loaded using only active-low CS, active-low WR, and DAC Select (active-low DAC A /DAC B) inputs.Each DAC has a separate reference input and internal feedback resistor which allow fully independent operation while maintaining excellent DAC-to-DAC matching. The MX7528 operates from a single +5 to +15V power supply whereas the MX7628 operates from +12V to +15V. The MX7528 has TTL compatible inputs at +5V supply only and the MX7628 has TTL compatible inputs from +12V to +15V supplies. The MX7528/MX7628 is supplied in 20-lead narrow DIP and Small Outline Packages.ApplicationsDigital-to-Synchro ConversionDigitally Controlled FiltersDisk DrivesMotion Control SystemsProgrammable AttenuatorsX-Y Graphic
