The ADN2820 is a compact, high performance, 3.3 V power
supply SiGe transimpedance amplifier (TIA) optimized for
10 Gbps Metro-Access and Ethernet systems. It is a single chip
solution for detecting photodiode current with a differential
output voltage. The ADN2820 features low input referred noise
current and high output transimpedance gain, capable of
driving a typical CDR or transceiver directly. A POWMON
output is provided for input average power monitoring and
alarm generation. Low nominal output offset enables dc output
coupling to 3.3 V circuits. The OFFSET control input enables
output slice level adjustment for asymmetric input signals. The
ADN2820 operates with a 3.3 V power supply and is available in
die form.
