Programmable Voltage Source with Increased Accuracy Over Reduced Output Range Using the AD5292 Digital Potentiometer, OP184 Op-Amp and MOSFETs

Programmable Voltage Source with Increased Accuracy Over Reduced Output Range Using the AD5292 Digital Potentiometer, OP184 Op-Amp and MOSFETs. This circuit provides a low cost, programmable, high voltage source with boosted output current using the AD5292 digital potentiometer in conjunction with the OP184 operational amplifier. The BSS138 PMOS transistor and Si2307CDS NMOS transistor provide current drive capability up to 2.5A
