PRODUCT DESCRIPTION
The ANADIGICS ATA00501 is a 5V low noise
transimpedance amplifier with AGC designed to be
used in OC-1 fiber optic links. The device is used in
conjunction with a photodetector (PIN diode or
avalanche photodiode) to convert an optical signal
into an output voltage. The ATA00501 has a bandwidth
of 70MHz and a dynamic range in excess of 40dB. It
is manufactured in a GaAs MESFET process and
available in bare die form or a 12 pin SQFP package.
