Original Press Release:

New 2W CMOS Power Amplifier Provides Excellent Sound Quality and Extends Battery Life in Notebook Computers and Portable Audio Equipment

San Jose, Calif.-November 19, 2002- Fairchild Semiconductor International (NYSE: FCS) announces the FAN7031, a CMOS stereo power amplifier optimized for noise performance and current consumption in notebook, desktop computer and portable audio equipment applications.

The FAN7031 is a dual, fully differential power amplifier in a 20-pin TSSOP-EP thermally enhanced package. The integrated, adaptive bias current control circuit of the FAN7031 significantly decreases crossover distortion, even though it consumes low quiescent current. With excellent THD (Total Harmonic Distortion) and PSRR (Power Supply Rejection Ratio) characteristics that are better than similar competing devices, the FAN7031 guarantees high output performance in portable audio applications.

The FAN7031 extends battery life in portable applications by consuming just 4 micro amps current in shutdown mode over the entire power supply range of 2.7V - 5.5V. It also allows Single Ended (SE) operation (pin selectable) for headphone drive. Internal gain adjustment is provided through two input pins. These features make the FAN7031 well suited for notebook computers and other portable/handheld equipment requiring audio output. The FAN7031 is complemented by a broad array of Fairchild's signal path solutions ranging from high-performance, low power operational amplifiers to analog switches that provide optimum performance with a minimum power budget.
