Through trimming, the ADA4511-2 achieves low offset drift (±0.4 μV/°C typical, ±2 μV/°C maximum) and low offset voltage (±25 μV typical, ±75 μV maximum). The ADA4511-2 delivers top DC accuracy and AC precision, which makes it suitable for a wide variety of signal chain applications. By integrating a robust mux-patible architecture, the ADA4511-2 effectively solves mon system distortion and settling problems and provides the superior accuracy required in multiplexed multichannel precision signal chains. The ADA4511-2 is specified from - 40°C to +125°C and is available in an 8-lead, SOIC_N and 8-lead, MSOP.
