GENERAL DESCRIPTION:

The AD8671/AD8672/AD8674 are very high precision amplifiersfeaturing very low noise, very low offset voltage and drift, lowinput bias current, 10 MHz bandwidth, and low powerconsumption. Outputs are stable with capacitive loads of over1000 pF. Supply current is less than 3 mA per amplifier at 30 V.The AD8671/AD8672/AD8674’s combination of ultralow noise,high precision, speed, and stability is unmatched. The MSOPversion of the AD8671/AD8672 requires only half the boardspace of comparable amplifiers.Applications for these amplifiers include high quality PLLfilters, precision filters, medical and analytical instrumentation,precision power supply controls, ATE, data acquisition, andprecision controls as well as professional quality audio.The AD8671/AD8672 are specified over the extended industrialtemperature range (−40°C to +125°C), and the AD8674 is specifiedover the industrial temperature range (−40°C to +85°C).The AD8671/AD8672 are available in the 8-lead SOIC and8-lead MSOP packages. The AD8674 is available in 14-leadSOIC and 14-lead TSSOP packages.Surface-mount devices in MSOP packages are available in tapeand reel only.
