CLC5526 Digital Variable Gain Amplifier (DVGA)
General Description
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 differential input and output, allowing large signal swings on a single 5V rail. The input impedance is 200Ω. The differential output impedance is 600Ω and is designed to drive a 1 kΩ differential load. The output amplifier has excellent intermodulation performance.
