LM4881M/NOPB

The LM4881M/NOPB is a Boomer dual 200mW Headphone Amplifier with shutdown mode capable of delivering 200mW of continuous average power into an 8Ω load with 0.1% THD+N from a 5V power supply. This Boomer audio power amplifier is designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4881 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The amplifier features an externally controlled, low power consumption shutdown mode which is virtually clickless and popless, as well as an internal thermal shutdown protection mechanism. The unity-gain stable can be configured by external gain-setting resistors.

• Unity-gain stable
• External gain configuration capability
• Thermal shutdown protection circuitry
• No bootstrap capacitors or snubber circuits are necessary
• Green product and no Sb/Br
