DESCRIPTION
The OPT201 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 FET- input 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 de- signs such as leakage current errors, noise pick-up and gain peaking due to stray capacitance. The OPT201 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, specified for the 0°C to 70°C temperature range.

Do not make electrical connection to the substrate. PIN CONFIGURATION ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with ap- propriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
