LM7131
Tiny High Speed Single Supply Operational Amplifier
General Description
The LM7131 is a high speed bipolar operational amplifier
available in a tiny SOT23-5 package. This makes the
LM7131 ideal for space and weight critical designs. Single
supply voltages of 3V and 5V provides good video perfor-
mance, wide bandwidth, low distortion, and high PSRR and
CMRR. This makes the amplifier an excellent choice for
desktop and portable video and computing applications. The
amplifier is supplied in surface mount 8-pin and tiny
SOT23-5 packages.
Tiny amplifiers are so small they can be placed anywhere on
a board close to the signal source or next to an A-to-D input.
Good high speed performance at low voltage makes the
LM7131 a preferred part for battery powered designs.
