AUDIO DRIVER
1. GENERAL DESCRIPTION
2. FEATURES
The GPY0031A (a bridge-tied load (BTL) and GPY0032A (a BTL
or singled-ended (SE)), are audio amplifiers, designed especially
for low-voltage applications which normally require internal
speaker. Operating on 5V power supply, GPY0031A / 32A is able
to deliver 2.0W of successive average power into 4Ω load at less
than 10% of THD+N throughout voice band frequencies and
embedded the de-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 GPY0031A
/ 32A are easily to be used in various applications and products.
Wide Operation Range: 2.0V – 6.8V
Bridge-Tied Load (BTL) (For GPY0031A)
Bridge-Tied Load (BTL) or Single-Ended (SE) Modes
Operation (For GPY0032A)
Low Distortion: THD+N = 0.15% (Typ.)
(For VDD = 5.0V, RL = 4.0Ω & Pout = 630mW)
High Output Power: POUT = 1.6W
(For VDD = 5.0V, THD+N =1.0%, f =1.0KHz & RL = 4Ω)
Low Shutdown Current: 1.0μA
Minimize the turn-on and turn-off pop noise
Thermal Shutdown Protection
Over Current Protection

Power Dissipation is major concern when designing a successful
amplifier, whether the amplifier is bridged or single-ended.

single-ended mode operating at a given supply voltage and driving
a specified output load.

6.6. Thermal Pad Considerations
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 thermal pad must be connected to ground. The package
with thermal pad of the GPY0031A/32A requires special attention
on thermal design. If the thermal design issues are not properly
addressed, the GPY0031A/32A will go into thermal shutdown
when driving an 8Ω load.
PD.MAX = (TJ.MAX-TJ) /θJA
(9)
For SOP-8 package with and without thermal pad, the thermal
resistance (θJA) is equal to 60°C/W and 160°C/W, respectively.
Thermal pad on the bottom of the GPY0031A/32A 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.
Since the maximum junction temperature (TJ.MAX
)
of
GPY0031A/32A 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.
If the ambient temperature is higher than 25°C, a larger copper
plane or forced-air cooling will be required to keep the
GPY0031A/32A junction temperature below thermal shutdown
temperature (150°C).
Example: VDD=6.0V, Load=8Ω, TA=30°C, GPY0031A SOP-8
without thermal pad (θJA=160°C/W).
In higher ambient temperature, higher airflow rate and/or larger
copper area will be required to keep the IC out of thermal
shutdown.
From equation 9:
PD.MAX = (150-30)/160 = 0.75W < 4(VDD)2 /(2π2 RL) = 0.913W
Decrease Power Voltage VDD to 5V.
PD.MAX = (150-30)/160 = 0.75W > 4(VDD)2 /(2π2 RL) = 0.634W
