Analog Devices Inc. ADA4511-2 Rail-to-Rail Input/Output Op Amps

Analog Devices Inc. ADA4511-2 Rail-to-Rail Input/Output Op Amps are dual-channel, 40V, high precision, low-input bias current, low-offset voltage, low-offset voltage drift, low noise, rail-to-rail input/output operational amplifiers (op amps). These devices can be used at any signal chain point, including sensing, conditioning, and output drive. Through trimming, the ADA4511-2 achieves low offset drift (±0.4μV/°C typical, ±2μV/°C maximum) and low offset voltage (±25μV typical, ±75μV maximum).

The Analog Devices ADA4511-2 delivers top DC accuracy and AC precision, making it suitable for various signal chain applications. By integrating a robust mux-compatible architecture, the ADA4511-2 effectively solves common system distortion and settling problems while providing the superior accuracy required in multiplexed multichannel precision signal chains. The ADA4511-2 is specified from -40°C to +125°C and available in an 8-lead, SOIC_N package.
