Color Sensor Evaluation Kit

Below are the operating characteristics of the

OPB780Z. As the ambient temperature or other

environmental conditions change, the values noted

may vary. The OPB780Z is designed to operate

between –40°C and +85°C. The OPB780Z provides

consistent recognition of a color given constant

environmental conditions.

Operating Characteristics at VDD = 5 V, TA = 25°C

Notes:

1. Irradiance Responsivity (Re) is measured over the range from Frequency 0 to 5 kHz.

2. Saturation Irradiance—(Full-Scale Frequency) / (Irradiance Responsivity)

3. Illuminance Responsivity is calculated from the Irradiance Responsivity using the appropriate wavelength

LED.

4. Nonlinearity is defined as the deviation of the Output Frequency utilizing a straight line between 0 and full

scale and is expressed as a percent of full scale.
