June 28, 2006 - New Japan Radio Co., Ltd. is pleased to announce the NJU7009, a low-noise, single CMOS operational amplifier engineered for signal processing of acceleration sensors, vibration sensors and optical sensors.
The NJU7009 features improved noise characteristics at low-voltage operation. It also boasts low-voltage operation (from 2.2V), low current consumption (330µA typ. VDD = 3V), and low noise (10nV√Hz typ. at f=1kHz), while offering 1pA (typ.) high input impedance characteristics. Moreover, the NJU7009 is ideally suited for signal processing of acceleration, vibration and optical sensors.
The NJU7009 enables you to configure a charge amp that combines an acceleration sensor and a vibration sensor for applications that detect acceleration and the direction of moving objects. It can also be connected to a photo diode for use in applications that detect optical signals in a current-voltage conversion process.
Compared to previous models, the NJU7009:
- Provides superior noise characteristics at low frequencies and is ideally suited for minute AC signal processing from an acceleration sensor or optical sensor.
- Features 3MHz wide band gain bandwidth to minimize waveform distortion and phase distortion generated from acceleration and vibration detection signal processing.
- Offers electrical characteristics at three operating voltage levels (2.2V, 3V, 5V) to provide greater flexibility in application designs.
