SoC Reduces ICs in Amplification Circuits
Using multibit Delta-Sigma audio converter technology, the CS47048 audio system-on-a-chip (SOC) from Cirrus Logic can reduce the number of ICs required to implement an automotive amplifier by as many as 10. Featuring a 4-channel ADC and a 32-bit audio DSP, the SOC has a 105 dB dynamic range and a -98 dB THD+N. The device uses integrated converters to simplify the management of audio sources at any sample rate up to 192 kHz. The SOC is available in a 100-pin LQFP package and is priced at $6.12 in quantities of 10,000.
