Nisshinbo Micro Devices Inc. Audio Amplifiers NJM2073M-TE2

The NJM2073M-TE2 is a dual low voltage power amplifier designed for audio applications in portable devices such as radios and cassette players. It operates within a voltage range of 1.8V to 15V and features low crossover distortion and low operating current, making it suitable for battery-powered applications. The amplifier can be configured in either bridge or stereo mode and is built using bipolar technology. The device has a maximum output peak current of 1A and offers power dissipation ratings of 700mW for the DIP8 package and 300mW for the DMP8 package. It operates effectively across a temperature range of -40¬8C to +85¬8C. The NJM2073M-TE2 provides output power of up to 2W at 9V with an 8,Ѷ load and maintains a total harmonic distortion (THD) of less than 0.2% at specified conditions. The input impedance is 100k,Ѷ, and it features a close loop voltage gain of approximately 44dB at 1kHz. Engineers considering this amplifier for their projects should note its compact design and efficiency, making it a viable option for low-power audio amplification needs.
