The MAS6116 is an ultra low noise stereo volume control for audio systems. When used in a balanced mono mode the linearity is an impressive 0.0002% (THD+N).
The design is based on resistor chains with external op-amps, which provide flexibility for the supply voltage, signal swing, noise floor and cost optimisation. The gain of each channel can be independently programmed from -111.5dB to +15.5dB through a digital serial control interface.
Audible clicks on gain changes are eliminated by changing gains only when a zero crossing has been detected in the signal.The device also features peak level detection, which can be used for AGC.
The MAS6116 is available in a 16 pin SOIC package.
Evaluation Board MAS6116EB is available for this product.
