NJU7026

NJU7026 Small Package, 13μ A, Rail-to-Rail Output Single CMOS Operational Amplifier ■ GENERAL DESCRIPTION The NJU7026 is a low power, single CMOS operational amplifier available in small packages, SC88A and MTP5. The NJU7026 can operate from a single-supply voltage of +1.8V to +5.5V. In addition, this amplifier features Rail-to-Rail output and low input bias current (1pA). Because of these features, the NJU7026 is ideal for low side current sense amplifier. The very low supply current of the NJU7026 (13μ A) makes it suitable for battery-operated application. ■ PACKAGE OUTLINE NJU7026F (SOT-23) NJU7026F3 (SC88A) ■ FEATURES •Low Supply Current •Low Operating Voltage •Rail-to-Rail Output •Small Package •CMOS Process 13μ A typ.
