This amplifier is based on an Analog Devices Inc. application note as shown in the SSM2220 datasheet, and a design completed by F. Seifert in 2007.

The amplifier has an input referred noise of ~0.3nV/rtHz, and is suitable for low source impedance ( ~1k ohm) applications such as the TCS ISS HgCdTe photodiode.
