The SSM2315 is a fully integrated, high efficiency, Class-D audioamplifier. It is designed to maximize performance for mobilephone applications. The application circuit requires a minimumof external components and operates from a single 2.5 V to 5.5 Vsupply. It is capable of delivering 3 W of continuous output powerwith <1% THD + N driving a 3 Ω load from a 5.0 V supply.
The SSM2315 features a high efficiency, low noise modulationscheme that requires no external LC output filters. The modulationcontinues to provide high efficiency even at low output power.It operates with 93% efficiency at 1.4 W into 8 Ω or 85% efficiencyat 3 W into 3 Ω from a 5.0 V supply and has an SNR of >103 dB.Spread-spectrum pulse density modulation is used to providelower EMI-radiated emissions compared with other Class-Darchitectures.
The SSM2315 has a micropower shutdown mode with a typicalshutdown current of 20 nA. Shutdown is enabled by applyinga logic low to the SD pin.
The device also includes pop-and-click suppression circuitry.This suppression circuitry minimizes voltage glitches at theoutput during turn-on and turn-off, reducing audible noiseon activation and deactivation.
The fully differential input of the SSM2315 provides excellentrejection of common-mode noise on the input. Input couplingcapacitors can be omitted if the dc input common-mode voltageis approximately VDD/2.
The default gain of the SSM2315 is 6 dB, but users can reduce thegain by using a pair of external resistors.
The SSM2315 is specified over the industrial temperature range of−40°C to +85°C. It has built-in thermal shutdown and outputshort-circuit protection. It is available in a 9-ball, 1.5 mm × 1.5 mmwafer level chip scale package (WLCSP).
