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 performance, 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.
