GENERAL DESCRIPTION

The AD8244 is a precision, low power, FET input, quad unity-gain buffer that is designed to isolate very large source impedances from the rest of the signal chain. The 2 pA maximum bias current, near zero current noise, and 10 T? input impedance introduce almost no error, even with source impedance well into the megaohms.
