SSM2377ACBZ Dettagli del prodotto

The SSM2377ACBZ 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 2.5 W of continuous output powerwith <1% THD + N driving a 4 Ω load from a 5.0 V supply.

The SSM2377ACBZ features a high efficiency, low noise modulationscheme that requires no external LC output filters. The modulationoperates with high efficiency even at low output power.

The SSM2377ACBZ operates with 92% efficiency at 1.4 W into 8 Ωfrom a 5.0 V supply and has an SNR of >100 dB.

Spread-spectrum pulse density modulation (PDM) is used toprovide lower EMI-radiated emissions compared with otherClass-D architectures. The inherent randomized nature ofspread-spectrum PDM eliminates the clock intermodulation(beating effect) of several amplifiers in close proximity.

The SSM2377ACBZ produces ultralow EMI emissions that significantlyreduce the radiated emissions at the Class-D outputs,particularly above 100 MHz. The SSM2377ACBZ passes FCC Class Bradiated emission testing with 50 cm, unshielded speaker cablewithout any external filtering. The ultralow EMI emissions of theSSM2377ACBZ are also helpful for antenna and RF sensitivity problems.

The device is configured for either a 6 dB or a 12 dB gain settingby connecting the GAIN pin to the VDD pin or the GND pin,respectively. Input impedance is a fixed value of 80 kΩ, independentof the gain select operation.

The SSM2377ACBZ has a micropower shutdown mode with a typicalshutdown current of 100 nA. Shutdown is enabled by applyinga logic low to the SD pin.

The device also includes pop-and-click suppression circuitry,which minimizes voltage glitches at the output during turn-onand turn-off, reducing audible noise on activation and deactivation.Built-in input low-pass filtering is also included to suppress outof-bandnoise interference to the PDM modulator.

The SSM2377ACBZ is specified over the industrial temperature rangeof −40°C to +85°C. It has built-in thermal shutdown and outputshort-circuit protection. It is available in a halide-free, 9-ball, 0.4 mmpitch, 1.2 mm × 1.2 mm wafer level chip scale package (WLCSP).
