The TPS851 is an ultra-compact surface-mount photo-IC for
illuminance sensors which incorporates a photodiode and current amp
circuit in a single chip.
The sensitivity is superior to that of a phototransistor, and exhibits
little variation.
It has spectral sensitivity closer to luminous efficiency and excellent
output linearity.
With its ultra-compact surface-mount package, this photo-IC can be
used as the power-saving control for domestic appliances or for
backlighting for displays in cellular phones, this device enables low
power consumption to be achieved.
