Product Description
The ANADIGICS ATA7601D1 is a 5V high-speed
transimpedance amplifier (TIA) for 10 Gb/s
applications available in bare die form and
manufactured using an InGaP HBT process.
The device is used in conjunction with a photodetector
to convert an optical signal into a differential voltage
that must be AC coupled to a post amplifier. With its
low input noise, a sensitivity of better than -19dBm
(BER <10
-10
) can be achieved with the ATA7601D1.
