What are VGAs? Variable gain amplifiers (VGAs) are signal-conditioning amplifiers with electronically settable voltage gain. There are analog VGAs and digital VGAs, or DVGAs. An analog voltage ...
The LMH6521 device contains two high performance, digitally controlled variable gain amplifiers (DVGA). Both channels of LMH6521 have an independent, digitally controlled attenuator followed by a high ...
Variable gain amplifiers often use a mechanical potentiometer to set the gain. An example is a volume control dial. However, when the analog signal path is digitally controlled, a digital ...
