QWhat is the input voltage range of the AD8061, when powered with +/-4V. Can I
amplify a 2Vpp signal with a gain of 3?
AAt +/-4V supply, the input range is -4.2V to 2.2V, and the part is Rail to Rail
Your input signal (+/-1V) is within the input range.
Your output signal (+/-3V) is also within the output range.
Unless the load you use is very light, you shouldn’t have a problem.
