TSL237T Description

Short technical summary and product information.

The TSL237T is a high-sensitivity light-to-frequency converter manufactured by ams OSRAM. This monolithic CMOS integrated circuit combines a silicon photodiode with a current-to-frequency converter, producing a square wave output directly proportional to light intensity. Its digital output allows for straightforward interfacing with microcontrollers.

Key electrical specifications include a single supply operation range of 2.7V to 5.5V and a wide input dynamic range of 5M:1. The device offers a stable temperature coefficient of 200ppm/°C and operates over a spectral range of 320nm to 1050nm, with temperature compensation for the ultraviolet-to-visible light range (320nm to 700nm).

Designed for low light level operation, the TSL237T features a low dark frequency of 0.1 Hz typical. It exhibits high irradiance responsivity of 1.2kHz/(μW/cm²) at λp = 640nm. The device is characterized for operation across a temperature range of -40°C to 85°C.

The TSL237T is supplied in a compact 4-lead surface-mount package (SMD) measuring 2.6mm x 3.8mm, simplifying board space requirements and design complexity. The output enable (OE) function places the output in a high-impedance state, facilitating multiple unit sharing of a microcontroller input line.
