Converts Light Intensity to Output Voltage,High Sensitivity
Single Voltage Supply Operation (2.7 V to 5.5 V)
High Power-Supply Rejection (35 dB at 1 kHz)
The TSL257 is a high-sensitivity low-noise light-to-voltage optical converter that combines a photodiode and a transimpedance amplifier on a single monolithic for CMOS integrated circuit.
proportional to light intensity (irradiance) on the photodiode. The TSL257 has a transimpedance gain of 320 MΩ.
The device has improved offset voltage stability and low power
