ADA4511-2数据手册ADI中文资料规格书

描述 Description

The ADA4511-21 is a dual-channel, 40 V, high precision, low-inputbias current, low-offset voltage, low-offset voltage drift, low noise,rail-to-rail input and output operational amplifier (op amp) that canbe used at any point of the signal chain, which includes sensing,conditioning, and output drive. Through trimming, the ADA4511-2achieves 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, whichmakes it suitable for a wide variety of signal chain applications. Byintegrating a robust mux-compatible architecture, the ADA4511-2effectively solves common system distortion and settling problemsand provides the superior accuracy required in multiplexed multichannelprecision signal chains. The ADA4511-2 is specified from−40°C to +125°C and is available in an 8-lead, SOIC_N package.
