SA AAIL/VI CMOS 8 Bit Multiplying D/A Converter General Description The MX7523 is high performance multiplying & 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 appli- cations. Thin-film resistors assure 8 bit resolution with up to 10 bit linearity (L grade) over the full operating tem- perature range. Im addition, all digital inputs are compatible with CMOS logic levels. Maxim's MX7523 is electrically and pin compatible with the Analog Devices AD 7423 and is available in a standard width 16-lead DIP as well as srmnall outline package. _ Applications Autamatic Test Equipment Digital Calibration Systems Battery Powered Instrumenis Audio Gain Contrat Digitally Controlled Filters Programmable Power Supplies Motion Controi Systems Pin Configuration hes | Veer | Fl / Ais el on 1) ape tae Ko. 2] NC.
