The objective is to design a low noise, wideband optical front-end system using the OPA855-Q1 as a transimpedance amplifier. The design requirements are:

• Amplifier supply voltage: 5 V
• TIA common-mode voltage: 3.8 V
• THS4520 gain: 1 V/V
• ADC input common-mode voltage: 1.3 V
• ADC analog differential input range: 1.1 V_PP
