OPT202

® OPT202 FPO PHOTODIODE WITH ON-CHIP AMPLIFIER FEATURES q BANDWIDTH: 50kHz q PHOTODIODE SIZE: 0.090 x 0.090 inch (2.29 x 2.29mm) q 1MΩ FEEDBACK RESISTOR q HIGH RESPONSIVITY: 0.45A/W (650nm) q LOW DARK ERRORS: 2mV q WIDE SUPPLY RANGE: ±2.25 to ±18V q LOW QUIESCENT CURRENT: 400µA q TRANSPARENT 8-PIN DIP AND 5-PIN SIP q HERMETIC 8-PIN CERAMIC DIP DESCRIPTION The OPT202 is an opto-electronic integrated circuit containing a photodiode and transimpedance amplifier on a single dielectrically isolated chip. The transimpedance amplifier consists of a precision FETinput op amp and an on-chip metal film resistor. The 0.09 x 0.09 inch photodiode is operated at zero bias for excellent linearity and low dark current. The integrated combination of photodiode and transimpedance amplifier on a single chip eliminates the problems commonly encountered in discrete designs such as leakage current errors, noise pick-up and gain peaking due to stray capacitance. The OPT202 operates over a wide supply range (±2.25 to ±18V) and supply current is only 400µA. It is packaged in a transparent plastic 8-pin DIP or 5-pin SIP, specified for the 0°C to +70°C temperature range as well as a hermetic ceramic 8-pin DIP with a glass window, specified for the –40°C to +85°C temperature range.
