® FPO OPT301 70% INTEGRATED PHOTODIODE AND AMPLIFIER FEATURES DESCRIPTION ● PHOTODIODE SIZE: 0.090 x 0.090 inch The OPT301 is an opto-electronic integrated circuit (2.29 x 2.29mm) containing a photodiode and transimpedance ● 1MΩ FEEDBACK RESISTOR amplifier on a single dielectrically isolated chip. The transimpedance amplifier consists of a precision FET- ● HIGH RESPONSIVITY: 0.47A/W (650nm) input op amp and an on-chip metal film resistor. The ● IMPROVED UV RESPONSE 0.09 x 0.09 inch photodiode is operated at zero bias for ● LOW DARK ERRORS: 2mV excellent linearity and low dark current. ● BANDWIDTH: 4kHz The integrated combination of photodiode and ● WIDE SUPPLY RANGE: ±2.25 to ±18V transimpedance amplifier on a single chip eliminates ● LOW QUIESCENT CURRENT: 400µA the problems commonly encountered in discrete de- signs such as leakage current errors, noise pick-up and ● HERMETIC TO-99 gain peaking due to stray capacitance. The OPT301 operates over a wide supply range (±2.25 APPLICATIONS to ±18V) and supply current is only 400µA. It is packaged in a hermetic TO-99 metal package with a ● MEDICAL INSTRUMENTATION glass window, and is specified for the –40°C to 85°C ● LABORATORY INSTRUMENTATION temperature range. ● POSITION AND PROXIMITY SENSORS ● PHOTOGRAPHIC ANALYZERS ● SMOKE DETECTORS SPECTRAL RESPONSIVITY Ultraviolet Infrared Red Blue Green Yellow 2 0.5 0.5 1MΩ Using Internal 4 0.4 0.4 1MΩ Resistor 40pF 0.3 0.3 0.2 0.2 75Ω 5 VO Voltage Output (V/µW) λ 0.1 0.1 Photodiode Responsivity (A/W) OPT301 0 0 831 100 200 300 400 500 600 700 800 900 1000 1100 V+ V– Wavelength (nm) International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.

Burr-Brown V+ NC recommends that all integrated circuits be handled with ap- 17Photodiode Area propriate precautions. Failure to observe proper handling and installation procedures can cause damage. –In 26NC 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 35 changes could cause the device not to meet its published V– Output 4 specifications. 1MΩ Feedback NOTE: Metal package is internally connected to common (Pin 8).
