The OPT201 is an opto-electronic integrated circuitcontaining a photodiode and transimpedanceamplifier on a single dielectrically isolated chip. Thetransimpedance amplifier consists of a precision FETinputop amp and an on-chip metal film resistor. The0.09 x 0.09 inch photodiode is operated at zero bias forexcellent linearity and low dark current.The integrated combination of photodiode andtransimpedance amplifier on a single chip eliminatesthe problems commonly encountered in discrete designssuch as leakage current errors, noise pick-up andgain peaking due to stray capacitance.The OPT201 operates over a wide supply range (±2.25to ±18V) and supply current is only 400mA. It ispackaged in a transparent plastic 8-pin DIP, specifiedfor the 0°C to 70°C temperature range.
