Overview

DESCRIPTION



· The NJU7056/NJU7057/NJU7058 are single/dual/quad rail-to-rail output CMOS operational amplifiers.

· They feature low noise of 15nV/√Hz and low offset drift of 0.7µV/°C, making them suitable for sensor and preamplifiers.

· Operates from 1.8V to 5.5V supply voltage, optimized for 2-cell battery and 1-cell Li-ion battery systems.

· High-impedance inputs with ground sensing, rail-to-rail output within 50mV from rail with 10kΩ load at 1.8V supply.

· Gain bandwidth of 2.1MHz and slew rate of 0.8V/µs, excellent for general-purpose applications.

· Available in various packages: NJU7056 in 5-pin SC-88A and SOT-23, NJU7057 in 8-pin MSOP and DFN, NJU7058 in 14-pin SSOP.
