The OPA350UA is a single-supply Operational Amplifier optimized for low voltage. Low noise as well as audio and general purpose applications. Single version for maximum design flexibility. The OPA350 series operates on a single supply as low as 2.5V with an input common-mode voltage range that extends 300mV below ground and 300mV above the positive supply. Output voltage swing is to within 10mV of the supply rails with a 10k load. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction.
