Keywords:amplifier rail-to-rail? sensor light? circuitry analog?

Light sensors are appearing in every sort of consumer application, aiding in aspects like power conservation. Since a wide range of products are portable, they use battery power and are therefore configured for single-supply operation. Single-supply operation introduces limitations on analog circuitry. One of the most obvious trade-offs is reduced input voltage range. Upgrading to a rail-to-rail amplifier will restore this sacrifice.
