2 / 63 page  www.ti.com DESCRIPTION TLV320AIC12, TLV320AIC13 TLV320AIC14, TLV320AIC15 TLV320AIC12K, TLV320AIC14K SLWS115E – OCTOBER 2001 – REVISED JANUARY 2007 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. The TLV320AIC1x is a true low-cost, low-power, high-integrated, high-performance, mono voice codec. It features one 16-bit analog-to-digital (A/D) channel and one 16-bit digital-to-analog (D/A) channel. The TLV320AIC1x provides high-resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology with programmable sampling rate. The TLV320AIC1x implements the smart time division multiplexed serial port (SMARTDM™). The SMARTDM port is a synchronous 4-wire serial port in TDM format for glue-free interface to TI DSPs (i.e. TMS320C5000™, TMS320C6000™) and microcontrollers. The SMARTDM supports both continuous data transfer mode and on-the-fly reconfiguration programming mode. The TLV320AIC1x can be gluelessly cascaded to any SMARTDM-based device to form multichannel codec and up to 16 TLV320AIC1x codecs can be cascaded to a single serial port. The TLV320AIC1x also provides a flexible host port. The host port interface is a two-wire serial interface that can be programmed to be either an industrial standard I2C or a simple S2C (start-stop communication protocol). The TLV320AIC1x also integrates all of the critical functions needed for most voice-band applications including MIC preamplifier, handset amplifier, headset amplifier, antialiasing filter (AAF), input/output programmable gain amplifier (PGA), and selectable low-pass IIR/FIR filters. The AIC12K also includes an 8- Ω speaker driver. The TLV320AIC1x implements an extensive power management; including device power-down, independent software control for turning off ADC, DAC, operational-amplifiers, and IIR/FIR filter (bypass) to maximize system power conservation. The TLV320AIC1x consumes only 11.2 mW at 3.3 V. The TLV320AIC1x low power operation from 2.7 V to 3.6 V power supplies, along with extensive power management, make it ideal for portable applications including wireless accessories, hands free car kits, VOIP, cable modem, and speech processing. Its low group delay characteristic makes it suitable for single or multichannel active control applications. The TLV320AIC1x is characterized for commercial operation from 0 °C to 70°C and industrial operation from -40 °C to 85°C. The TLV320AIC1xk is characterized for industrial operation from -40°C to 85°C.
