1 General Description The AAT5 is a high efficiency, high performance stereo class D audio amplifier. It is designed to operate in a wide supply voltage range from.5v to 5.5V and is targeted to deliver up to.5w output power to a 4Ω load with 5V power supply. Efficiency of up to 9.5% makes it ideal for portable applications. The AAT5 has four adjustable amplifier gains with 6,, 8 and 4dB programmed by two external pins. Two shutdown control pins are employed to control the left and right channels independently. The AAT5 also integrates over-temperature protection circuitry to prevent internal junction temperature over-heating. The AAT5 is offered in a Pb-free, thermally enhanced, space-saving.645mm.645mm 6-pin WLCSP package and in the 3mm 3mm 6-pin QFN package, and is specified for operation over the -4 C to +85 C ambient temperature range.

12 PGA PGA Voltage Gain (db) Input Impedance (kω) Table : Gain Setting. Input High-Pass Filter C IN is the input DC blocking capacitor which forms input high pass filter with amplifier input impedance. The corner frequency is determined from the equation: Where: f -3dB = f -3dB is -3dB corner frequency R I is the input resistance C I is the input capacitance π R I C I The value of C I is important for the bass performance of the amplifier. The capacitors should have a tolerance of ±% or better. Power Supply Bypassing The AAT5 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. Thermal Protection The AAT5 features unlatched over temperature protection. During operation when the device junction temperature exceeds 45 C (typical), the device enters into shutdown state and outputs are disabled. Once device junction temperature is reduced by 5 C, the device leaves shutdown state and returns to normal operation automatically. DATA SHEET AAT5 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 (T ON ). 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. OUT+ AAT5 OUT - Ferrite Bead nf Ferrite Bead nf Figure : Typical Ferrite Bead Filter. Skyworks Solutions, Inc.

The AAT5 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. At any given ambient temperature (T A ), the maximum package power dissipation can be determined by the following equation: P D(MAX) = T J(MAX) - T A θ JA The T J (MAX), the maximum junction temperature for the device is 5 o C. The package thermal resistance θ JA is 9.4 o C/W for the WLCSP-6 package. For example, given T A =5 o C, from above formula, the maximum power dissipation is.w. With given efficiency η, the max output power can be determined by the following equation: P O(MAX) = P D(MAX) - η Skyworks Solutions, Inc.
