CLC5526 - National Semiconductor

CLC5526 Digital Variable Gain Amplifier (DVGA)

The CLC5526 is a high performance, digitally controlled, variable-gain amplifier (DVGA). It has been designed for use in a broad range of mixed signal and digital communication applications such as mobile radio, cellular base stations and back-channel modems where automatic-gain-control (AGC) is required to increase system dynamic range. The CLC5526 has diff.
