SSM2211SZ

SSM2211 is a high performance audio amplifier. It delivers 1W rms of low distortion audio power into a bridge connected 8 ohm speaker load (or 1.5W rms into a 4 ohm load). This device operates over a wide temperature range and is specified for single-supply voltages between 2.7V and 5.5V. When operating from batteries, it continues to operate down to 1.75V. This makes the device the best choice for unregulated applications, such as toys and games. 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. It is widely used in application such as portable computers, personal wireless communicators, hands-free telephones, speaker phones, intercoms, musical toys and talking games etc.

• Wide bandwidth is 4MHz typical
• Highly stable phase margin is <gt/>80°
• Total Harmonic Distortion is 0.2% typical at (P = 1W into 8 ohm, f = 1KHz)
• Excellent power supply rejection
• Supply current is 9.5mA typical at (VOUTA = VOUTB = 2.5V, −40°C ≤ TA ≤ +85°C)
• Operating temperature is -40°C to +85°C
• Package style is 8-lead SOIC-N
