DESCRIPTION
The OPT301 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 OPT301 operates over a wide supply range (±2.25 to ±18V) and supply current is only 400μA. It is packaged in a hermetic TO-99 metal package with a glass window, and is specified for the –40°C to 85°C temperature range.
