New Japan Radio releases the NJU7089

Tokyo, Japan, July 28, 2011 - New Japan Radio Co., Ltd. has introduced to the market the NJU7089, low voltage operation 1.2W monaural power amplifier suitable for audio power amplifier of battery-powered equipments such as fire alarm.

[Background of development]

Fire alarm and IC recorder are generally battery operation. They require low voltage operation ICs mounted in them, because of long life operation with putting the battery performance to best use. Further IC recorder often employs differential type DAC output for noise reduction.

To meet these needs, New Japan Radio Co., Ltd. has developed the NJU7089, 1.2W monaural power amplifier with low voltage operating and differential type input.

[Key Features]

NJU7089

No.1 Suitable for battery-powered equipments by 1.8V low voltage operation
The NJU7089 operates from low voltage of 1.8V corresponds to two dry-cell batteries final voltage(0.9V×2)*1. It can put the battery performance to best use.
No.2 Providing sufficient acoustic pressure with 1.2W output
The NJU7089 provides sufficient acoustic pressure using fire alarm application with 1.2W output, 20% higher than other similar products.
No.3 Providing mounting area reduction by compact low-profile package
We prepare compact low-profile package type.
The NJU7089 is a need for higher density equipments such as an IC recorder,provided a compact, low- profile package. (ESON8-V1 : 2.3×2.3×0.397mm)
It can be reduced by 40%*2 compared with an equivalent mounting area than its competitors.
