📥 Download Datasheet

General Description

The LMH6523 contains four, high performance, digitally controlled variable gain amplifiers (DVGA).

It has been designed for use in narrowband and broadband IF sampling applications.

Typically, the LMH6523 drives a high performance ADC in a broad range of mixed signal and digital communication applications such as mobile radio and cellular base stations where automatic gain control (AGC) is required to increase system dynamic range.
