General Description

The THAT1570 is a versatile, high performance current-feedback amplifier suitable for differential microphone preamp and bus summing applications.

The IC comes in a small QFN package, which saves PCB space over discrete and other integrated solutions.

Gain is adjusted via three external resistors (RA, RB, and RG), making it possible to optimize noise over a wide range of gains.
