XR1009, XR2009
0.2mA, 35MHz Rail-to-Rail Amplifiers
General Description
The XR1009 (single) and XR2009 (dual) are ultra-low power, low cost,
voltage feedback ampli ers. These ampli ers use only 208μA of supply
current and are designed to operate from a supply range of 2.5V to 5.5V
(±1.25 to ±2.75).The input voltage range extends 300mV below the negative
rail and 1.2V below the positive rail.
The XR1009 and XR2009 offer superior dynamic performance with a
35MHz small signal bandwidth and 27V/μs slew rate. The combination of
low power, high bandwidth, and rail-to-rail performance make the XR1009
and XR2009 well suited for battery-powered communication/ computing
systems.
