CSC-IC CJC8974A

The CJC8974A is a low power, high quality stereo CODEC designed for portable digital audio applications and a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 4 Ω load with less than 10% THD when powered by a 5V power supply. The device integrates complete interfaces to ONE stereo headphone or line out ports. The CJC8974A can operate as a master or a slave, with various master clock frequencies including 12 or 24MHz for USB devices, or standard 256fs rates like 12.288MHz and 24.576MHz.

DESCRIPTION

External component requirements are drastically reduced as no separate headphone amplifiers are required. Advanced on-chip digital signal processing performs graphic equaliser, 3-D sound enhancement and automatic level control for the microphone or line input. Different audio sample rates such as 96kHz, 48kHz, 44.1kHz are generated directly from the master clock without the need for an external PLL. To conserve power in portable applications, the CJC8974A micropower shutdown mode (IQ =0.6µA, typ) is activated when VDD is applied to the SHUTDOWN pin.Boomer audio power amplifiers are designed specifically to provide high power, high fidelity audio output. They require few external components and operate on low supply voltages from 2.0V to 5.5V.
