AUDIO DRIVER
1. GENERAL DESCRIPTION
2. FEATURES
The GPY0030C is an audio driver, in which gain can be adjusted
by external resistor (Maximum gain is 20) and embedded the
anti-pop circuit to minimize the turn-on and turn-off pop noise.
Normally, it is applied for GPC series, GPF series, GPL series and
other GENERALPLUS products. The GPY0030C is easily to be
used in variety of applications and products.
Wide operating range: 2.4V – 6.8V
Bridge-Tied Load
Low distortion: THD+N = 0.15% (Typ.)
(For VDD = 5.0V, RL = 8.0 & Pout = 500mW)
High output power: POUT = 825mW
(For VDD = 5.0V, THD+N =1.0%, f =1.0KHz & RL = 8.0)
Low standby current: 1.0A
Minimize the turn-on and turn-off pop noise

6.1. BTL Amplifier Efficiency
Since the GPY0030C has two operational amplifiers in one
package, the maximum internal power dissipation is four times
that of a single-end amplifier. The maximum power dissipation
from equation 8 must not be greater than the power dissipation
that results from the equation 9.
The following equations are basis for amplifier efficiency
calculation.

resistance (θJA) is equal to 60°C/W and 160°C/W, respectively.

Since the maximum junction temperature (TJ.MAX) of GPY0030C is
150°C and ambient temperature (TA) is defined by the power
system design, the maximum power dissipation which the IC
package is able to handle from equation 9. Once the power
dissipation is greater than the maximum limit (PD.MAX), either the
supply voltage (VDD) must be decreased, the load impedance (RL)
must be increased, or the θJA must be reduced with heat-sink.

6.3. Thermal Pad Considerations
* High-peak voltage values cause the THD to increase.
The thermal pad must be connected to ground. The package
with thermal pad of the GPY0030C requires special attention on
thermal design. If the thermal design issues are not properly
addressed, the temperature beyond which damage occurs to the
GPY0030C (150°C). The GPY0030C may not function or meet
expected performance at this temperature.
6.2. Power Dissipation
Power dissipation is a major concern when designing a successful
amplifier, whether the amplifier is bridged or single-ended.
Equation 7 states the maximum power dissipation point for a
single-ended mode operating at a given supply voltage and driving
a specified output load.
Thermal pad on the bottom of the GPY0030C should be soldered
down to a copper pad on the circuit board. Heat can be
conducted away from the thermal pad through the copper plane to
ambient. The copper plane used to conduct heat away from the
thermal pad should be as large as practical.
PD.MAX = (VDD)2 /(2π2 RL)
Single-Ended (7)
However, a direct consequence of the increased power delivered
to the load by bridge amplifier is an increment in internal power
dissipation point for a bridge amplifier operating at the same
condition.
If the ambient temperature is higher than 25°C, a larger copper
plane or forced-air cooling will be required to keep the GPY0030C
junction temperature below maximum junction temperature
(150°C).
PD.MAX = 4(VDD)2 /(2π2 RL)
