Hello:
I am working with the VCA810 and have subjected it to a -2.9V control voltage, I have read in the application notes that voltages below -2.5V should be avoided to prevent saturation. Is it possible that subjecting the below that threshold will damage the IC. I had baised a DAC in the system to operated between 0-1.9V to get a maximum amplification of a power amp. Using an analog switch, the circuit is flexible to allow an AGC to drive the VCA810. I had installed a 2.2V zener on the output of the AGC to protect against a voltage under -2.2; however, this circuit did not do what I had intended and have put -2.9 into the VCA.
I have went back to driving the VCA with the DAC circuit and find that the max value on the amp has changed to something much lower.
Could the VCA810 now be damaged?
