MX7545

The MX7545 is a 12-bit CMOS multiplying digital-to-analog converter (DAC) with internal data latches.Input data is loaded as a single 12-bit word and latched under the control of
CS and WR input.When CS and WR are low,the input data latches are transparent and the DAC output responds to any changes in the digital input.MX7545 works with a single +5V or +15V power supply.Electrical characteristics are specified at both of these supply voltages.With a +5V supply,the digital input are =5V TTL and CMOS compatible while high voltage CMOS compatibility is maintained at +15V supply range.Maxim MX7545 uses low tempco thin-film resistors which are laster-trimmed to result in linearity errors that are typically ±1/4 LSB and gain errors of maximum ±1 LSB (G grade).The digital input are designed with improved protection againest electrostic discharge (ESD) damage and can typically withstand to over 6,000V of ESD voltages.The MX7545 is supplied in 20-lead narrow DIP and small outline packages.

The MX7545 has some absolute maximum ratings (Ta=+25 unless otherwise stated).The VDD to DGND is -0.3 to +17V.The digital input voltage to DGND is -0.3 to VDD.The VRFB,VREF to DGND is ±25V.The Vout to DGND is -0.3 to VDD.The AGND to DGND is -0.3 to VDD.The power dissipation to +75(any package) is 450mW.The derate above 75 by 6mW/.The storage temperature is -65 to +150.The lead temperature (soldering 10 seconds) is +300.
