XR8051, XR8052, XR8054
Low Cost, High Speed Rail-to-Rail Amplifiers
General Description
The XR8051 (single), XR8052 (dual) and XR8054 (quad) are low cost,
voltage feedback amplifiers. These amplifiers are designed to operate on
+3V to +5V, or ±5V supplies. The input voltage range extends 300mV below
the negative rail and 0.9V below the positive rail.
The XR8051, XR8052, and XR8054 offer superior dynamic performance
with a 260MHz small signal bandwidth and 190V/μs slew rate. The
combination of low power, high output current drive, and rail-to-rail
performance make these amplifiers well suited for battery-powered systems
and video applications.
The combination of low cost and high performance make the XR8051,
XR8052, and XR8054 suitable for high volume applications in both
consumer and industrial applications such as video surveillance and
distribution systems, professional and IPC cameras, active filter circuits,
coaxial cable drivers, and electronic white boards.
