Notes

1. The device's sensitivity is approximately proportional to its power supply (VDD) voltage. The input

gain must compensate for this and also prevent the input circuitry saturating. It is recommended

that the amplifier components (R1 to R4, C1 and C2) are used to set the gain between -10dB (if

VDD is 5.0V) and -13dB (if VDD is 3.3V).
