functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to GND.
2. Output may be shorted to supply.

NOTES:
3. The input irradiance E
e
is supplied by a GaAlAs infrared-emitting diode with
λ
p
= 880 nm.
4. Irradiance responsivity is characterized over the range V
O
= 0.05 to 3 V.
