Variable Gain Amplifiers

Analog Devices’ variable gain amplifiers (VGA), IF variable gain amplifiers and variable gain control products offer the high performance requirements of the communications, instrumentation, and military designs. ADI’s VGA portfolio includes continuous analog linear and digital step controlled products that provide as fine as 0.25 dB step and linear in volts digital control. ADI’s highly integrated RF VGA work with digitally controlled multipole analog filters integrated on-chip and with AGC circuits for automatic level control.

Analog Control VGAs

Analog Devices voltage controlled variable gain amplifiers provide continuous gain control over a wide dynamic range for a variety of audio and optical frequency bands.

Baseband Programmable VGA-Filters

ADI RF VGAs, IF VGAs, and variable gain control products offer the high performance needed for communications, instrumentation, and military designs.

Digital Control VGAs

ADI digital controlled variable gain amplifiers provide discrete levels of gain control over a fixed number of control bits for a variety of audio and optical frequency bands.
