产品详情

The SSM6322 is an integrated, dual-channel audio amplifier solution that interfaces directly with audio DAC/CODEC, maximizing the fidelity of high fidelity audio signal chains. The highly efficient design of the SSM6322 delivers outstanding audio performance while minimizing power dissipation for maximum battery life in portable applications.

The SSM6322 features −121 dB THD + N at 1 kHz, along with very low output noise from 20 Hz to 20 kHz. The low power operation, high peak output current, and high PSRR make the SSM6322 an ideal candidate for applications that require high fidelity audio, high dynamic range, precision, and low power. This highly integrated drive solution also reduces development time while reducing board space and minimizing external components.

The SSM6322 is available in a 24-lead LFCSP package. The SSM6322 operates over the industrial temperature of −40°C to +85°C.
