The SSM3302ACPZ is a fully integrated, high efficiency, stereo Class-D audio amplifier. The application circuit requires minimal external components and operates from a single 7 V to 18 V supply. The device is capable of delivering 2×10 W of continuous output power into a 4 Q load(or2x8 W into 8Q) with<1% THD+N from a 12 V supply. In addition, while mono mode is activated, the user can drive a load as small as 2 Q up to 20 W continuous output power by stacking the stereo output terminals.
The SSM3302ACPZ features a high efficiency, low noise modulation scheme that requires no external LC output filters.

This schemecontinues to provide high efficiency even at low output power.lbad or with 82% efficiency at 10 W into 4Q from a12 V supply.
and it has an SNRof>98dB.Spread spectrum pulse density modulation (PDM) is used toprovide lower EMI radiated emissions compared with other Class-D architectures. The SSM3302ACPZ includes an optional modulation select pin(ultralow EMI emission mode) that significantly reduces the radiated emissions at the Class-D outputs, particularly above 100 MHz.

The SSM3302ACPZ can pass FCC Class-B emissions testing with an unshielded 20 inch cable using common-mode choke-based filtering.
The fully differential input of the SSM3302ACPZ provides excellent rejection of common-mode noise on the input. The device also includes a highly flexible gain select pin that only requires one series resistor to choose a gain between 9 dB and 24dB, with no change to the input impedance. The benefit of this is to improve gain matching between multiple SSM3302ACPZ devices within a singleapplication compared with using extemal resistors to set gain.
The SSM3302includes an integrated voltage regulator that gnerates a 5 V rail.
The SSM3302ACPZ has a micropower shutdown mode with a typicalshutdown current of 10uA. Shutdown is enabled by applyinga logic low to the SD pin. The device also includes pop-and-lick suppression circuitry that minimizes voltage glitches at the output during turn on and turn ofreducing audible noise during activation and deactivation.
Other included features to simplify system level integration of the SSM3302ACPZ are input low-pass filtering to suppress out-of-
band DAC noise interference to the pulse density modulator, fixed input impedance to simplify component selection across multiple platform production builds, and a thermal warning indicatorpin.
The SSM3302ACPZ is specified over the commercial temperature range(-40℃ to+85℃). It has built-in thermal shutdown and output short-circuit protection. It is available in a halide-free,
40-lead,6 mm ×6 mm lead frame chip scale package(LFCSP).

The SSM3302ACPZ operates with 90% efficiency at 7 W into an 8Q
