The TLV320AIC10 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 provide on-chip include timing (programmable sample rate, continuous data transfer, and FIR bypass) and control (programmable-gain amplifier, communication protocol, etc.). The sigma-delta architecture produces high-resolution analog-to-digital and digital-to-analog conversion at low system cost.
The TLV320AIC10 design enhances communication with the DSP. The continuous data transfer mode fully supports TIs DSP autobuffering (ABU) to reduce DSP interrupt service overhead. The automatic cascading detection (ACD) makes cascade programming simple and supports a cascade operation of one master and up to seven slaves. The direct-configuration mode for host interface uses a single-wire serial port to directly program internal registers without interference from the data conversion serial port, or without resetting the entire device. The event monitor mode allows the DSP to monitor external events like phone off-hook ring detection.
In the lower-power mode, the TLV320AIC10 converts data at a sampling rate of 8 KSPS consuming only 39 mW.
The programmable functions of this device are configured through a serial interface that can be gluelessly interfaced to any DSP that accepts 4-wire serial communications, such as the TMS320Cxx. The options include software reset, device power-down, separate control for ADC and DAC turnoff, communications protocol, signal-sampling rate, gain control, and system-test modes, as outlined in Appendix A.
The TLV320AIC10 is particularly suitable for a variety of applications in hands-free car kits, VOIP, cable modem, speech, and the telephony area including low-bit rate, high-quality compression, speech enhancement, recognition, and synthesis. Its low-group delay characteristic makes it suitable for single or multichannel active-control applications.
The TLV320AIC10 is characterized for commercial operation from 0°C to 70°C, and industrial operation from 40°C to 85°C.
