LM7121
235 MHz Tiny Low Power Voltage Feedback Amplifier
General Description
The LM7121 is a high performance operational amplifier
which addresses the increasing AC performance needs of
video and imaging applications, and the size and power con-
straints of portable applications.
The LM7121 can operate over a wide dynamic range of sup-
ply voltages, from 5V (single supply) up to
±
15V (see the Ap-
plication Information section for more details). It offers an ex-
cellent speed-power product delivering 1300V/μs and 235
MHz Bandwidth (3 dB, A
= +1). Another key feature of this
operational amplifier is stability while driving unlimited ca-
pacitive loads.
Due to its Tiny SOT23-5 package, the LM7121 is ideal for
designs where space and weight are the critical parameters.
The benefits of the Tiny package are evident in small por-
table electronic devices, such as cameras, and PC video
cards. Tiny amplifiers are so small that they can be placed
anywhere on a board close to the signal source or near the
input to an A/D converter.
