NJM2172
OPERATIONAL AMPLIFIER WITH EVR
s GENERAL DESCRIPTION The NJM2172 is single supply, dual OP-AMP with electric variable resistor (EVR), which contains buffer amplifier, OP-AMP, reference voltage circuit, EVR and EVR control circuit. + The reference is fixed around 1/2 V level internally, and only required few external parts. The A and B EVR is control separately, and amp drive up to 100(typ.) load. The NJM2172 is suitable for camcorder, CD, MD, and other audio signal process system. s FEATURES q Low Power Supply Voltage q Low Operating Current q A/Bch EVR adjust is separately q EVR range q Drivability q Bipolar Technology q Package Outline s BLOCK DIAGRAM s PACKAGE OUTLINE
