TSL253R
Light-to-Voltage Optical Sensor
General Description
The TSL253R is a light-to-voltage optical sensor combining a
photodiode and a transimpedance amplifier
(feedback resistor = 16 MΩ) on a single monolithic IC. Output
voltage is directly proportional to the light intensity (irradiance)
on the photodiode. The device has improved amplifier
offset-voltage stability and low power consumption and is
supplied in a 3-lead clear plastic sidelooker package with an
integral lens.
Ordering Information and Content Guide appear at end of
datasheet.

TSL253R − 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 Operating
Conditions is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

Note(s):
1. Measurements are made with RL = 10kΩ between output and ground.
2. Optical measurements are made using small-angle incident radiation from an LED optical source.
3. The input irradiance E e is supplied by an AlInGaP LED with peak wavelength λ p = 635nm
4. The temperature coefficient of output voltage measurement is made by adjusting irradiance such that VO is approximately 2V at
25°C and then with irradiance held constant, measuring VO while varying the temperature between 0°C and 70°C.
5. Irradiance responsivity is characterized over the range V O = 0.05 to 2.9V. The best-fit straight line of Output Voltage V O versus
irradiance Ee over this range will typically have a positive extrapolated V O value for Ee = 0.

TSL253R − RoHS Compliant & ams Green Statement
RoHS Compliant & ams Green
Statement
RoHS: The term RoHS compliant means that ams AG products
fully comply with current RoHS directives. Our semiconductor
products do not contain any chemicals for all 6 substance
categories, including the requirement that lead not exceed
0.1% by weight in homogeneous materials. Where designed to
be soldered at high temperatures, RoHS compliant products are
suitable for use in specified lead-free processes.
ams Green (RoHS compliant and no Sb/Br): ams Green
defines that in addition to RoHS compliance, our products are
free of Bromine (Br) and Antimony (Sb) based flame retardants
(Br or Sb do not exceed 0.1% by weight in homogeneous
material).
Important Information: The information provided in this
statement represents ams AG knowledge and belief as of the
date that it is provided. ams AG bases its knowledge and belief
on information provided by third parties, and makes no
representation or warranty as to the accuracy of such
information. Efforts are underway to better integrate
