     CXAS42235 CXAS42235A is a input/output rail-to-rail Operational Amplifier. It can be operated from +2.2V to +7V single supply or from ±1.1V to ±3.5 dual supply. CXAS42235 CXAS42235A can drive 66mA into resistor loads to within 10% power rail. AC performance is very excellent with 6.5MHz bandwidth, 6.5V/μs Slew Rate, 95dB open loop gain, 60 degree phase margin and low distortion. Supply current of CXAS42235 CXAS42235A is only 500μA per Amplifier. It is very suitable for low current consumption applications to control high current loads. Applications include audio amplification for computers, sound ports, sound cards and set-top boxes. CXAS42235 CXAS42235A is housed in a 5-pin small SOT-23-5 and SC-70-5 (SOT-353) package.
