LM4995SD/NOPB

The LM4995SD/NOPB is an Audio Power Amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.2W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. Boomer audio power amplifier was designed specifically to provide high quality output power with a minimal amount of external components. The LM4995 does not require output coupling capacitors or bootstrap capacitors and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement. The LM4995 features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the LM4995 features an internal thermal shutdown protection mechanism.

• Ultralow current shutdown mode
• BTL output can drive capacitive loads
• Improved click and pop circuitry eliminates noise during turn-on and turn-off transitions
• No output coupling capacitors, snubber networks or bootstrap capacitors required
• Unity-gain stable
• External gain configuration capability
• 0.1µA (typical) Shutdown current
• Green product and no Sb/Br
