ZHCSMN3B February 2021 – January 2023 OPA855-Q1
PRODUCTION DATA
The objective is to design a low noise, wideband optical front-end system using a diverse selection of optical sensors: PD, APD, PMT, and MPPC with the OPA855 as the TIA. The approximate design requirements for each type of photodetector are listed in Table 10-1.
