AAT5102
2.5W/Ch Stereo Class D Audio Power Amplifier
General Description
Features
The AAT5102 is a high efficiency, high performance stereo class D audio amplifier. It is designed to operate in a
wide supply voltage range from 2.5V to 5.5V and is targeted to deliver up to 2.5W output power to a 4Ω load
with× 5V power supply. Efficiency of up to 90.5% makes
it ideal for portable applications.
• Wide Supply Voltage Range (2.5V to 5.5V)
• Maximum Battery Life and Minimum Heat
▪ 5mA Quiescent Current at 3.6V VDD
▪ <1μA Shutdown Current
▪ Up to 90.5% Efficiency
• Output Power at 10% THD+N
▪ 2.5W x2 to 4Ω at 5V VDD
▪ 1.6W x2 to 8Ω at 5V VDD
• High Performance
▪ THD+N of 0.03%, at 5V VDD, 8Ω Load and POUT =
1.0W
SNR
of 102dB at 5V VDD, 8Ω Load and 1% THD+N
▪
• Shutdown Control
▪ Independent Control per Channel1
▪ Internal 300kΩ Pull-down Resistors
• Filter-less Capability
• Four Programmable Gains: 6, 12, 18 and 24dB
• Thermal Protection
• Excellent PSRR
• Built-in Pop-click Suppression Circuitry
• 1.645mm × 1.645mm 16-Pin WLCSP Package
• 3mm × 3mm 16-Pin QFN Package
The AAT5102 has four adjustable amplifier gains with 6,
12, 18 and 24dB programmed by two external pins. Two
shutdown control pins are employed to control the left
and right channels independently.
The AAT5102 also integrates over-temperature protection circuitry to prevent internal junction temperature
over-heating.
The AAT5102 is offered in a Pb-free, thermally enhanced,
space-saving 1.645mm × 1.645mm 16-pin WLCSP package and in the 3mm × 3mm 16-pin QFN package, and is
specified for operation over the -40°C to +85°C ambient
temperature range.

Application Information
Gain Setting
The AAT5102 is a closed loop pulse-width-modulated
switch mode power amplifier for driving bridge-tied load.
It features high performance with high efficiency, high
SNR and low THD+N. It also offers built-in over-temperature protection.
The AAT5102 voltage gain can be programmed to 6, 12,
18 and 24dB via two inputs, PGA1 and PGA0. See Table
1 for gain setting.

Input High-Pass Filter
CIN is the input DC blocking capacitor which forms input
high pass filter with amplifier input impedance. The corner frequency is determined from the equation:
f-3dB =
1
2 · π · RI · CI
Where:
f-3dB is -3dB corner frequency
RI is the input resistance
CI is the input capacitance
The value of CI is important for the bass performance of
the amplifier. The capacitors should have a tolerance of
±10% or better.
Power Supply Bypassing
The AAT5102 is a high performance Class-D amplifier,
adequate supply decoupling is necessary for overall better performance. A good low equivalent series resistance
(ESR) decoupling capacitor of 4.7μF or larger is recommended.
Shutdown Mode
When SDR and SDL are pulled down to low voltage, the
device is in its maximum power saving mode. In shutdown mode, outputs are pulled in weak low state. The
high logic level applied on SDR and SDL wakes up the
device after turn-on time (TON). When independent shutdown control for each channel is necessary in the application, connecting the audio source ground to the device
ground is highly recommended.
Output Filter
A ferrite bead should be used to reduce EMI emissions if
EMI sensitive devices nearby in the system. The ferrite
bead acts essentially as high impedance to a high frequency emissions but very low impedance to low frequency signal. Choose the ferrite bead with high impedance at the frequency range of interest.

Thermal Protection
The AAT5102 features unlatched over temperature protection. During operation when the device junction temperature exceeds 145°C (typical), the device enters into
shutdown state and outputs are disabled. Once device
junction temperature is reduced by 15°C, the device
leaves shutdown state and returns to normal operation
automatically.

Thermal Considerations
and Maximum Output Power
The AAT5102 delivers a 5W power to 4Ω speaker. The
limiting characteristic for the maximum output power is
essentially package power dissipation and the device
internal thermal limit.
The TJ (MAX), the maximum junction temperature for the
device is 125oC. The package thermal resistance θJA is
90.4oC/W for the WLCSP-16 package. For example,
given TA=25oC, from above formula, the maximum
power dissipation is 1.1W. With given efficiency η, the
max output power can be determined by the following
equation:
At any given ambient temperature (TA), the maximum
package power dissipation can be determined by the following equation:
PD(MAX)
PO(MAX) = 1 - η
PD(MAX) =
TJ(MAX) - TA
θJA
