opa2314 pdf datasheet (RRI/O CMOS运算放大器)
The OPA314 family of single, dual, and quad channel operaTIonal amplifiers represents a new generaTIon of low-power, general-purpose CMOS amplifiers. Rail-to-rail input and output swings, low quiescent current (150 µA typ at 5.0 VS) combined with a wide bandwidth of 3 MHz, and very low noise (14 nV/√Hz at 1 kHz) make this family very attracTIve for a variety of battery-powered applicaTIons that require a good balance between cost and performance. The low input bias current supports applications with mega-ohm source impedances.
The robust design of the OPA314 devices provides ease-of-use to the circuit designer: unity-gain stability with capacitive loads of up to 300 pF, an integrated RF/EMI rejection filter, no phase reversal in overdrive conditions, and high ESD protection (4-kV HBM).
