The MAX9619AXT+T is a single, zero-drift, high efficiency, 1.5MHz operational amplifier (op-amp) with RRIO in 6 pin SC-70 package. This device uses an innovative auto-zero technique that allows precision and low noise with a minimum amount of power. The low input offset voltage, CMOS inputs and the absence of 1/f noise allows for optimization of active filter designs. It achieves rail to rail performance at the input through use of a low noise charge pump. This ensures a glitch-free, common-mode input voltage range extending from the negative supply rail up to the positive supply rail, eliminating crossover distortion common to traditional n-channel/p-channel CMOS pair inputs, reducing harmonic distortion at the output. Device is ideal for loop-powered systems that interface with pressure sensors or strain gauges.
