These devices have improved amplifier offset-voltage stability and low power consumption and are supplied in a -lead plastic sidelooker package with an integral visible light cutoff filter and lens. When supplied in the lead (Pb) free package, the device is RoHS compliant.

Measurements are made with R L = 0 kω between output and ground.. Optical measurements are made using small-angle incident radiation from an LED optical source.. The input irradiance E e is supplied by a GaAs LED with peak wavelength λ p = 90 nm. Irradiance responsivity is characterized over the range V O = 0.0 to.9 V. The best-fit straight line of Voltage V O versus irradiance E e over this range will typically have a positive extrapolated V O value for E e = 0.
