SIGMA-DELTA ANALOG INTERFACE CIRCUITS WITH MASTER-SLAVE FUNCTION

The TLC32047 wide-band Analog Interface circuit (AIC) is a complete Analog-to-digital and digital-to-analog Interface system for advanced digital signal processors (DSPs) similar to the TMS32020, TMS320C25 and TMS320C30. The TLC32047 offers a powerful combination of options under DSP control: three operating modes [dual-word (telephone interface), word, and byte] combined with two word formats (8 bits and 16 bits) and synchronous or asynchronous operation. It provides a high level of flexibility in that conversion and sampling rates, Filter bandwidths, input circuitry, receive and transmit gains, and multiplexed Analog inputs are under processor control.
