The OPA4244EA/250 is a quad MicroPower? Operational Amplifier designed for very low quiescent current (50μA/channel), yet achieves excellent bandwidth. It is ideal for battery-powered applications. The quad version feature completely independent circuitry for lowest crosstalk and freedom from interaction, even when overdriven or overloaded. The OPA244 series is easy to use and free from phase inversion and overload problems found in some other op amp. This amplifier is stable in unity gain and excellent performance is maintained as they swing to their specified limits. The input common-mode voltage range includes ground - ideal for many single supply applications.
