Product Description

Product Details
The AD8641/AD8642/AD8643 are low power, precision JFET input amplifier featuring low input bias current and rail-to-rail output. The AD8641 family provides high source impedance, low bias current and low supply current which are key to applications such as ECG/EKG monitors, sleep monitoring, and blood analyzing instruments. The ability to swing rail-to-rail at the output enables designers to buffer wide output swing devices in single supply systems.
The AD8641 family is also ideal for applications utilizing multi-channel boards that require low power to manage heat. Other applications include photodiodes, ATE reference level drivers, battery management, and industrial controls.
The AD8641 family is fully specified over the extended industrial temperature range of –40° to +125°C. The AD8641 is available in 5-lead SC70 and 8-lead SOIC packages. The AD8642 is available in 8-lead MSOP and 8-lead SOIC packages. The AD8643 is available in 16-lead 3mm x 3mm LFCSP and 14-lead SOIC packages.
