TSL267
High-Sensitivity IR Light-to-Voltage
Converter
The TSL267 is a high-sensitivity low-noise infrared
light-to-voltage converter that combines a photodiode and a
transimpedance amplifier on a single monolithic CMOS
integrated circuit. Output voltage is directly proportional to IR
light intensity (irradiance) on the photodiode. The TSL267 has
a transimpedance gain of 320 MΩ. The device has improved
offset voltage stability and low power consumption and is
supplied in a 3-lead visible-light-blocking plastic sidelooker
package with an integral lens.
Ordering Information and Content Guide appear at end of
datasheet.

TSL267 − Electrical Characteristics
Electrical Characteristics at VDD = 5 V, TA = 25°C, λp = 940 nm,
RL = 10kΩ (unless otherwise noted) see notes (1), (2), (3).
Figure 8:
Electrical Characteristics
Note(s):
1. Measurements are made with RL = 10 kΩ between output and ground.
2. Optical measurements are made using small-angle incident radiation from an LED optical source.
3. The input irradiance is supplied by a GaAs light-emitting diode with the following characteristics: peak wavelength λp = 940 nm.
4. Irradiance responsivity is characterized over the range VO = 0.1 to 4.5 V. The best-fit straight line of Output Voltage VO versus
irradiance Ee over this range will typically have a positive extrapolated VO value for Ee = 0.
5. Power supply rejection ratio PSRR is defined as 20 log (ΔVDD(f )/ΔVO(f)) with VDD(f = 0) = 5 V and VO(f = 0) = 2 V.

TSL267 − 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).
