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.

(1) For supply voltage less than ±4V (8V), the absolute maximum rating is equal to the supply voltage.

(2) Differential voltage is the voltage difference between +INPUT and -INPUT.

(3) Input voltages outside the supply voltage will be clamped by ESD protection diodes. If the input voltage exceeds the supply voltage, the

input current must be limited 1mA or less by using a restriction resistance.

(4) Power dissipation is the power that can be consumed by the IC at Ta=25°C, and is the typical measured value based on JEDEC

condition.
