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 MΩ 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.

Measured with RL = 10 kΩ between output and ground. 3. Optical measurements are made using small-angle incident radiation from a light-emitting diode (LED) optical source. 4. The input irradiance is supplied by an InGaN light-emitting diode with the following characteristics: peak wavelength λ p = 470 nm, spectral halfwidth Δλ ‰ = 35 nm, luminous efficacy = 75 lm/W. 5. The input irradiance is supplied by an InGaN light-emitting diode with the following characteristics: peak wavelength λp = 524 nm, spectral halfwidth Δλ ‰ = 47 nm, luminous efficacy = 520 lm/W. 6.

Responsivity is characterized over the range VO = 0.1 V to 4.5 V. The best-fit straight line of Output Voltage VO versus Irradiance Ee over this range will typically have a positive extrapolated VO value for Ee = 0. 8. The input irradiance is supplied by a GaP light-emitting diode with the following characteristics: peak wavelength λp = 565 nm, spectral halfwidth Δλ ‰ = 28 nm, luminous efficacy = 595 lm/W. 9. Illuminance responsivity RV is calculated from the irradiance responsivity by using the LED luminous efficacy values stated in Notes 4, 5, 6, and 8, and using 1 lx = 1 lm/m2. 10. Power supply rejection ratio PSRR is defined as 20 log (ΔVDD (f)/ΔVO (f)) with VDD (f = 0) = 5 V and VO (f = 0) = 2 V.
