THAT1580 Description
The THAT1580 is a versatile, high performance current-feedback amplifier suitable for differential microphone preamp and bus summing applications. The IC es in a small 4 x 4 mm 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.
