Digital Automatic Gain Control (AGC) technology that allows for "Smart" amplification, optimizing the signal for lowest noise and highest throughput.
has introduced the next-generation differential digital gear tooth sensor with a two-wire back-biased package, peak detecting algorithems and automatic gain control.
The device also includes automatic gain control (AGC) that provides dynamic range of more than 35dB, and is fabricated in sub-micron complementary oxide semiconductor (CMOS) process for high performance.
Designed for easy installation, the receiver has automatic gain control, which compensates for variations in video gain or frequency.
It acquires all necessary analog signals including optical power reflected power, temperature and laser diode current These controllers have the capability to process and react to data in <5 [micro]s, resulting in up to a 200 kHz response rate in a typical automatic gain control (AGC) loop.
