Detailed Description
The MAX9730 Class G power amplifier with inverting
charge pump is the latest in linear amplifier technolo-
gy. The Class G output stage offers the performance
of a Class AB amplifier while increasing efficiency to
extend battery life. The integrated inverting charge
pump generates a negative supply capable of deliver-
ing up to 500mA.
The Class G output stage and the inverting charge pump
allow the MAX9730 to deliver an output power that is up
to four times greater than a traditional single-supply linear
amplifier. This allows the MAX9730 to maintain 0.8W into
an 8Ω load as the battery rail collapses.
Class G Operation and Efficiency
The MAX9730 Class G amplifier is a linear amplifier that
operates within a low (VCC to GND) and high (VCC to
SVSS) supply range. Figure 1 illustrates the transition
from the low to high supply range. For small signals,
the device operates within the lower (VCC to GND) sup-
ply range. In this range, the operation of the device is
identical to a traditional single-supply Class AB amplifi-
er where:
ILOAD = IN1
As the output signal increases, so a wider supply is
needed, the device begins its transition to the higher sup-
ply range (VCC to SVSS) for the large signals. To ensure a
seamless transition between the low and high supply
ranges, both of the lower transistors are on so that:
ILOAD = IN1 + IN2
As the output signal continues to increase, the transi-
tion to the high supply is complete. The device then
operates in the higher supply range, where the opera-
tion of the device is identical to a traditional dual-sup-
ply Class AB amplifier where:
ILOAD = IN2
During operation, the output common-mode voltage of
the MAX9730 adjusts dynamically as the device transi-
tions between supply ranges.
