NJM741M is an instrumentation buffer amplifier with high common mode rejection ratio (CMRR) and offset null capabilities, making it a popular choice for many manufacturers. It is also used in other applications such as medical instrumentation, data processing, automatic test equipment, telecommunications, and integrated circuits. The NJM741M is a current feedback, dual input, dual output, low power amplifier. It has a low input bias current which makes it ideal for high quality, low current operation. It is made of a pair of complementary versions of the basic NJM741 series device. The NJM741M has a very wide gain bandwidth, low distortion and can handle both AC and DC signals.

The NJM741M is a direct coupled amplifier with a common emitter input stage and cascode emitter follower output stage. This makes it well suited for signal conditioning, signal amplification, isolation or impedance matching. The low input impedance and the high input current of the device allow a stable operating environment. The cascode output stage provides the necessary high voltage gain and wide bandwidth. The small signal bandwidth and high open loop gain of this device provide excellent isolation and excellent signal isolation. The large output voltage swing and low distortion also make the NJM741M a good choice for high performance analog applications.

The NJM741M is typically used in high speed applications such as medical instrumentation, data processing, automatic test equipment and integrated circuits. The large signal bandwidth and low distortion make it an ideal choice for applications where a very high frequency response is required. It also features an offset nulling capability which makes it well suited for applications where an offset nulling circuit is desired. This feature eliminates the need for manual adjustment and saves time and cost in many applications.

As with most linear amplifiers, the NJM741M’s gain is determined by the ratio of the feedback resistor to the input impedance. The input impedance determines the open loop gain, the gain of the device is then determined by the ratio of the feedback resistor to this input impedance. The accuracy of the amplifier depends on the quality of the feedback resistor as well as on the accuracy of the input impedance.

The NJM741M operates with input voltages from ±5V to ±15V and output voltages from 0V to +30V. It is capable of handling input and output currents up to 20mA and can operate in temperature ranges up to 90°C. The NJM741M is designed to operate at frequencies up to 900kHz and is capable of operating with a power supply of up to±15V. It features an open-loop voltage gain of 90dB and a common-mode rejection ratio (CMRR) of 95dB.

In summary, the NJM741M is a solid state, high performance instrumentation buffer amplifier with high common mode rejection and offset null capabilities. It features low current operation and a wide gain bandwidth, low distortion and excellent isolation. The NJM741M is an ideal choice for high speed applications such as medical instrumentation, data processing, automatic test equipment and integrated circuits. It is an excellent choice for high performance analog applications.
