MX7548

The MX7548 is a 12-bit CMOS,current output,multiplying digital-to-analog converter (DAC) with a versatile interface for microprocessors using 8-bit busses.The MX7548 accepts data into its input-registers in teo bytes in eighter left-or righ-justified format,least sicnificant byte or most significant byte first.Standard WR and CSLSB or CSMSB inputs control the data load operation.A separate LDAC input controls transfer of data from the input register to the DAC register allowing for simultaneous update of all DACs in multi-DAC systems.A data overrie input forces the DAC output to full-scale or zero-code without altering the contents of the input registers.This permits the user to perform DAC calibration converniently without having to load calibration data into the DAC.The MX7548 works with a single +5V,+12V or +15V power supply,and the electrical characteristics are specified at all of these supply voltage.All digital inputs are TTL and +5V-CMOS compatible with any of these supply voltages.Maxim MX7548 uses low tempco thin-film resistors which are laster trimmed to ±1/4LSB linearity and better than ±LSB gain accuracy.The digital inputs are designed with improved ESD protection and can typically withstand over 5,000V of ESD voltages.The MX7548 is supplied in 20-lead narrow DIP,PLCC,and small outline packages.
