PRODUCT DESCRIPTION
The ANADIGICS AMT8312, packaged in a 5 pin
TO-46 lens can, is a 3.3 V integrated photodetector
and transimpedance amplifier (TIA) used to convert
a short wavelength (850 nm) input optical signal into
a differential output voltage. The AMT8312 has a
bandwidth of 1.8 GHz, a dynamic range of over
23 dB and a photocurrent monitor with an output that
is proportional to the average input optical power.
These devices are readily designed into receivers,
transceivers and transponders for SONET, Fibre
Channel and Infiniband applications.
