Description
The TSLB257, TSLG257, and TSLR257 are high-sensitivity low-noise light-to-voltage optical converters that
incorporate onboard blue, green, and red optical filters, respectively. These devices 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 M
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.
