Many system configurations require multiple transducers normalized gain offset, prior further conversion signal processing. Xicor X9241A quad XDCPs provide elegant efficient solution performing these tasks under microprocessor control. configuration Figure 1shows dual amps being controlled single quad XDCP. gain range this configuration trimmed between -0.5 -2.0 over steps. Increasing (the feedback determining network example) 100K will change gain trim range between -0.91 -1.1. inverting configuration shown particularly suitable this allows input signals vary from without violating digital pots terminal voltage specifications +5V/-3V. offset trimming configuration shown Figure same pair dual amps. This configuration yields offset trimming range ±300mV over steps. offset range increased decreased changing value amplifier example). Changing will decrease offset range ±40mV finer resolution, less range desired. This configuration also ensures that

Potpourri Amplifier
Figure illustrates microprocessor controlled circuit that provide adjustable gain from infinity with pots quad X9241AW XDCP. other pots ganged together using cascade mode extended offset range. purpose this circuit solve particular analog signal processing problem, rather demonstrate analog control flexibility that attained with X9241A. With overall gain from input output will Gain values range over steps incrementing value Setting back setting results overall gain Increasing yields gain plus infinity. This essentially positive comparator with threshold level being cascade combination National Semiconductor's LMC6482 nice amplifier this application because rail-to-rail input output range.
