Texas Instruments (LM4861M) Audio Power Amplifier, 500 mW, AB

Audio Power Amplifier, 500 mW, AB, 1 Channel, 2V to 5.5V, SOIC, 8 Pins Product Overview The LM4861M is a 1.1W Audio Amplifier with shutdown mode. This Boomer series audio power amplifier capable of delivering 1.1W of continuous average power to an 8R load with 1% THD+N using a 5V power supply. Boomer audio power amplifier designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the LM4861 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. This amplifier features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable can be configured by external gain-setting resistors for differential gains of up to 10 without the use of external compensation components. Higher gains may be achieved with suitable compensation. No output coupling capacitors, bootstrap capacitors or snubber circuits are necessary Compatible with PC power supplies Thermal shutdown protection circuitry Unity-gain stable External gain configuration capability Applications Audio, Computers & Computer Peripherals, Portable Devices Product Information Output Power: 500mW Amplifier Class: AB No. of Channels: 1 Channel Supply Voltage Range: 2V to 5.5V Amplifier Case Style: SOIC No. of Pins: 8Pins Load Impedance: 8ohm Operating Temperature Min: -20°C Operating Temperature Max: 85°C MSL: MSL 1 - Unlimited
