Photodiode, Transconductance Amplifier,

and Feedback Components

Description

The TSL12S, TSL13S, and TSL14S are cost-optimized, highly integrated light-to-voltage optical sensors, each

combining a photodiode and a transimpedance amplifier (feedback resistor = 80 MΩ, 20 MΩ, and 5 MΩ,

respectively) on a single monolithic integrated circuit. The photodiode active area is 0.5 mm

sensors respond to light in the range of 320 nm to 1050 nm. Output voltage is linear with light intensity

(irradiance) incident on the sensor over a wide dynamic range. These devices are supplied in a 3-lead clear

plastic sidelooker package (S). When supplied in the lead (Pb) free package, the device is RoHS compliant.
