ADA4511-2ARZ

ADA4511-2ARZ is a dual-channel, 40V, high precision, low-input bias current, low-offset voltage, low-offset voltage drift, low noise, rail-to-rail input and output operational amplifier (op-amp) that can be used at any point of the signal chain, which includes sensing, conditioning, and output drive. It delivers top DC accuracy and AC precision, which makes it suitable for a wide variety of signal chain applications. By integrating a robust mux-compatible architecture, the ADA4511-2 effectively solves common system distortion and settling problems and provides the superior accuracy required in multiplexed multichannel precision signal chains. It is used in applications such as data acquisition systems, multiplexed input signal chains, industrial automation, medical instruments, electronic test and measurement, precision current measurement, and photodiode amplifiers.
