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 package. NJU7057 is available in 8-pin MSOP
(TVSP): meet JEDEC MO-187-DA / thin type package
and DFN that is thin and 2mm square small package.
NJU7058 is available in 14-pin SSOP package.
