The ADA4511-2 is a dual-channel, 40 V, 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. 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-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. The ADA4511-2 is specified from −40°C to +125°C and is available in an 8-lead, SOIC_N package.
