Description

The NJM2740 is a dual low saturation output operational amplifier featuring low noise of 6.5nV/√Hz. It can be used both single supply and dual supply, by using proper bias voltage. Low operating voltage single 2.2V to 7V or dual ±1.1V to ±3.5V and low saturation output performance makes NJM2740 suitable for Battery-powered instruments, portable audio devices that require a low voltage and low saturation output. The NJM2740 is available in 8-pin DMP, SSOP and MSOP(TVSP): meet JEDEC MO-187-DA / thin type package.
