NCNR (non cancelable / non returnable)
Audio Power Amplifier, LM4861M/NOPB, Texas Instruments
The LM4861M/NOPB is a bridge-connected audio power amplifier capable of delivering 1.1W of continuous average power to an 8Ω load with 1% THD+N using a 5V power supply. The Boomer audio power amplifier was designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the LM4861M/NOPB does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optimally suited for a low-power portable system. The LM4861M/NOPB features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4861M/NOPB can be configured by an external gain-setting resistor for a differential gain of up to 10 without the use of an external compensation component. Higher gain may be achieved with suitable compensation.
