DESCRIPTION
This device incorporates an integral photodiode, amplifier, Schmitt trigger, and internally pulled-up output stage.
An on-chip voltage regulator allows operation over a wide range of available supply voltage. The phase of the
digital output is considered to be inverted from the optical input, so that the output is HI when the light source is
OFF, and the output is LOW when the light source is ON.
An adjust pin (ADJ) is provided to allow the user to alter the optical threshold at which the output changes state.
Decreasing the resistance between this pin and ground causes the output to switch at higher and higher input
levels, to a maximum of about 1.66mW/cm2 , or about 3.5µW on the photodiode.
