New Japan Radio Co., Ltd. announces the NJM2754, 4-input/1-output stereo audio selector with ground noise isolation amplifier. The ground noise isolation amplifier is suitable for rejection of common mode noise, which occurs between car-mounted audio equipment and external-connection equipments such as potable audio-devices.
Recently, in car-audio market, due to the evolution of external-connection equipments such as CD changer, DVD player and portable digital audio player raises the demand for high quality sound. The ground noise isolation amplifier is suitable for achieving high quality sound with rejection of common mode noise between car-mounted audio equipment and external-connection devices.
The NJM2754 consists of four stereo ground noise isolation amplifiers, 4-input / 1-output stereo audio selector and buffers. It makes possible 63.6% circuit board reduction in space by integrating isolation amplifiers and audio selector on one chip.The NJM2754 has high common mode noise reduction ratio (CMRR=60dB), superior channel separation (CS=110dB) and low noise (1.7µVrms typ.).
The NJM2754 is suitable for car-mounted audio equipment, due to high performance, space-efficiency and multiple input response.
