TSL1401CL − Detailed Description
The voltage developed at analog output (AO) is given by:
V
out
= V
drk
+ (R
e
) (E
e
) (t
int
)
where:
V
out
is the analog output voltage for white condition
V
drk
is the analog output voltage for dark condition
R
e
is the device responsivity for a given wavelength of
light given in V/(μJ/cm
2
)
E
e
is the incident irradiance in μW/cm
2
t
int
is integration time in seconds
A 0.1μF bypass capacitor should be connected between V
DD
and ground as close as possible to the device.
The TSL1401CL is intended for use in a wide variety of
applications, including: image scanning, mark and code
reading, optical character recognition (OCR) and contact
imaging, edge detection and positioning, and optical linear and
rotary encoding.

TSL1401CL − Absolute Maximum Ratings
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. These are stress
ratings only. Functional operation of the device at these or any
other conditions beyond those indicated under Electrical
Characteristics is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.
