THAT1570 - Audio Preamplifier IC
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 (
