TLV320AIC11 描述
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.
TLV320AIC11 特性
- 16-bit oversampling sigma-delta A/D converter
- 16-bit oversampling sigma-delta D/A converter
- Maximum output conversion rate:
- 22 ksps with on-chip FIR filter
- 88 ksps with FIR bypassed
- Voiceband bandwidth in FIR-bypassed mode and final sampling rate at 8 ksps
- 90-dB SNR/ADC and 87-dB SNR/DAC with DSP’s FIR (FIR bypassed @ 88 ksps/5 V)
- 87-dB SNR/ADC and 85-dB SNR/DAC with DSP’s FIR (FIR bypassed @ 88 ksps/3.3 V)
- On-chip FIR produced 84-dB SNR for ADC and 85-dB SNR for DAC over 11-kHz BW
- Built-in functions including PGA, antialiasing analog filter, and operational amplifiers for general-purpose interface (such as MIC interface and hybrid interface)
- Glueless serial port interface to DSPs (TI TMS320UC54x or standard DSPs)
- Automatic cascading detection (ACD) makes cascade programming simple and allows up to 8 devices to be connected in cascade.
- On-fly reconfiguration modes include secondary-communication mode and direct-configuration mode (host interface).
- Continuous data-transfer mode for use with autobuffering (ABU) to reduce DSP interrupt service overhead
- Event-monitor mode provides external-event control, such as RING/OFF-HOOK detection
- Programmable ADC and DAC conversion rate
- Programmable input and output gain control
- Separate software control for ADC and DAC power-down
- Low-voltage (DVDD1) 1.1-V to 3.6-V digital I/O
- Analog (AVDD1 and AVDD2) 3 V to 5.5 V core power supply
