General Description
The optical receiver device consists of a first stage transimpedance amplifier (TIA) with differential input, limiting amplifiers with integrated high pass filter characteristics and differential outputs OUTP_LA / OUTN_LA and a secondary linear output OUT.
A very high sensitivity equivalent to a transimpedance resistance of typ. 422MΩ is achieved at the limiting outputs. By using a limiting amplifier no phase shift occurs if the input is overdriven. Ambient light equivalent to a constant photo current up to 10mA is suppressed with an integrated gyrator.
