TSLB257 - BLUE Light to Voltage Converter


  • Monolithic Silicon IC Containing Photodiode, Op Amp, and Feedback Components
  • Integral Blue Color Filter
  • High Sensitivity
  • Low Noise (200uVrmsTypical )
  • Rail-to-Rail Output
  • High Power-Supply Rejection (35 db at 1kHz)


The TSLB257 is a high-sensitivity low-noise light-to-voltage optical converter that incorporate onboard blue optical filter. The TSLB257 combine a photodiode and a transimpedance amplifier on a single monolithic CMOS integrated circuit with a color filter over the photodiode. Output voltage is directly proportional to light intensity (irradiance) on the photodiode. Each device has a transimpedance gain of 320 Megohm with improved offset voltage stability and low power consumption, and is supplied in a 3-lead clear plastic sidelooker package with an integral lens. These devices are ideal for applications such as colorimetry, printing process control, display color correction, and selectively ambient light detection or rejection. Click here for datasheet.
