The gain of that circuit is only about 100 (40dB), which probably won't be adequate, and despite what the manual says, it won't run off of 3V. At 3V, the input signal is biased at 1.5V, which is of course only 1.5V below the chip's supply voltage, a point above which it will not operate. Put another way, there is zero headroom if operated at 3V. The only thing it will amplify without severe distortion is total silence.
