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.

Evaluation Kits 1
EVAL-SSM6322
SSM6322 Evaluation Board
Product Detail
The SSM6322 evaluation board, the SSM6322CP-EBZ, evaluates the SSM6322 which is offered in a 24-lead LFCSP package. The SSM6322CP-EBZ evaluation board is a 4-layer printed circuit board (PCB) designed to quickly evaluate the performance of the device and reduce design time. The SSM6322CP-EBZ accepts SMA edge mounted connectors to test equipment or other circuitry.
Complete specifications for the SSM6322 device are provided in the SSM6322 data sheet and should be consulted in conjunction with user guide UG-1097 when using the evaluation board.
