PRODUCT DESCRIPTION The ANADIGICS ATA7602 is a -5.2V high speed transimpedance amplifier (TIA) for 10Gb/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 can be AC or DC coupled to a post amplifier. The DC offset between the two outputs can be adjusted in order to maintain low dury cycle distortion for large signal operation or to provide an adjustable decision threshold for the post amplifier.
