The Osram TSL257SM-LF is a high-sensitivity, low-noise light-to-voltage optical converter designed for ambient light sensing applications. This monolithic silicon IC integrates a photodiode and a transimpedance amplifier, providing an output voltage directly proportional to light intensity.
Key electrical specifications include a wide supply voltage range of 2.7V to 5.5V and a transimpedance gain of 320MΩ. The device exhibits low noise, typically 200µVrms to 1kHz, and high power-supply rejection of 35dB at 1kHz. It responds to visible light in the 400nm to 700nm wavelength range, with a specific peak sensitivity around 470nm.
The TSL257SM-LF is supplied in a 3-lead SMD, Side View package, suitable for surface mounting with a right-angle orientation. The operating temperature range is from 0°C to 70°C. This component is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1.
This sensor is ideal for applications requiring accurate detection of ambient light levels, such as display brightness control, lighting automation, and portable electronic devices.
