General Description

The NJU7056/NJU7057/NJU7058 are Single/Dual/Quad rail-to-rail output CMOS operational amplifiers. Low noise of 15nV/√Hz and low offset drift of 0.7µV/°C typ. make them suitable for several sensor amplifiers and preamplifiers. NJU7056/NJU7057/NJU7058 operate from 1.8V to 5.5V supply voltage. They are optimized for 2-cell battery systems and 1-cell li-ion battery systems. The NJU7056/NJU7057/NJU7068 have high-impedance inputs with ground sense, rail-to-rail output that swings within 50mV from rail with 10kΩ load at 1.8V supply, 2.1MHz Gain bandwidth and 0.8V/µs Slew rate. These characteristics make them excellent performance for general-purpose applications. The NJU7056 is available in 5-pin SC-88A and SOT-23 packages. The NJU7057 is available in 8-pin MSOP(TVSP): meet JEDEC MO-187-DA / thin type package and ESON that is thin and 2mm square small package. The NJU7058 is available in 14-pin SSOP package.
