Характеристики

SSM2211SZ, Аудиоусилитель с низкими искажениями, 0.2% …The SSM2211SZ is a Low Distortion Audio Power Amplifier that delivers 1Wrms of low distortion audio power into a bridge connected 8R speaker load (or 1.5Wrms into a 4R load). It operates over a wide temperature range and is specified for single-supply voltages between 2.7 and 5.5V. When operating from batteries, it continues to operate down to 1.75V. This makes the SSM2211 best choice for unregulated applications, such as toys and games. Featuring a 4MHz bandwidth and distortion below 0.2% THD + N at 1W, superior performance is delivered at higher power or lower speaker load impedance than competitive units. The low differential DC output voltage results in negligible losses in the speaker winding and makes high value DC blocking capacitors unnecessary. The battery life is extended by using shutdown mode, which typically reduces quiescent current drain to 100nA. Applications include personal portable computers, hands-free telephones and transceivers, talking toys, intercom systems.

• 1.5W Output with THD + N 80°)
• Low distortion (0.2% THD + N at 1W output)
• Excellent power supply rejection
