The TLV320AIC11 provides high resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology. It allows 2-to-1 MUX inputs with built-in antialiasing filter and amplification for general-purpose applications such as telephone hybrid interface, electret microphone preamp, etc. Both IN and AUX inputs accept normal analog signals. This device consists of a pair of 16-bit synchronous serial conversion paths (one for each direction), and includes an interpolation filter before the DAC and a decimation filter after the ADC. The FIR filters can be bypassed to offer flexibility and power savings. Other overhead functions provided on-chip include timing (programmable sample rate, continuous data transfer, and FIR bypass) and control (programmable-gain amplifier, communication protocol, etc.
