NJU7027 Series

13µA/ch, Rail-to-Rail Output CMOS Operational Amplifier

The NJU7026/NJU7027/NJU7028 are single, dual and quad rail-to-rail output single supply CMOS operational amplifiers featuring low supply current. These amplifiers operates from single 1.8V to 5.5V supply or dual ±0.9V to ±2.75V supply and provide a 160kHz gain-bandwidth products while using only 13µA of supply current per channel, ideal for 2-cell battery systems and 1-cell li-ion battery systems. NJU7026/NJU7027/NJU7028 have rail-to-rail outputs that typically swing to within 50mV of the rails with 100kΩ load and the input common mode voltage range includes negative supply rail and swing to within 0.9V of the positive rail. These characteristics make them suited for low-side current sense applications. In addition to low power and rail-to-rail output, very low bias current make them to used for photodiode amplifiers, charge amplifiers, piezoelectric sensors and other applications with high source impedance. NJU7026/NJU7027/NJU7028 are high RF-immunity to reduce malfunctions caused by RF noises from mobile phones and others. The NJU7026 is available in 5-pin SC-88A and SOT-23 package. NJU7027 is available in 8-pin MSOP (TVSP): meet JEDEC MO-187-DA / thin type package and DFN which is thin and 2mm square small package. NJU7028 is available in 14-pin SSOP package.
