Fairchild Debuts FAN7031 CMOS Power Amplifier
Fairchild Semiconductor International (San Jose, CA) announced the FAN7031, a CMOS power amplifier optimized for noise performance and current consumption in notebook, desktop computer and portable audio equipment applications. The integrated, adaptive bias, current-control circuit of the FAN7031 decreases crossover distortion, even though it consumes low quiescent current.
The FAN7031 extends battery life in portable applications by consuming just 4µA of current in shutdown mode over the entire power supply range of 2.7V to 5.5V. The device also allows single-ended operation for headphone drive. Internal gain adjustment is provided through two input pins, making the FAN7031 suitable for notebook computers and other portable and hand-held equipment requiring audio output.
The FAN7031 power amplifier comes in a 20-pin, TSSOP-EP, thermally enhanced package. Available now, pricing for the FAN7031 is $1.20 in 1,000-piece quantities. Delivery is 8 to 10 weeks ARO.
