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 TLV320AIC2x is a low-cost, low-power, highly-integrated, high-performance, dual-voice codec. It features
two 16-bit analog-to-digital (A/D) channels and two 16-bit digital-to-analog (D/A) channels, which can be
connected to a handset, headset, speaker, microphone, or a subscriber line via a programmable analog
crosspoint.
The TLV320AIC2x 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 TLV320AIC2x 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
DSP platforms) and microcontrollers. The SMARTDM supports both continuous data transfer
mode and on-the-fly reconfiguration programming mode. The TLV320AIC2x can be gluelessly cascaded to any
SMARTDM-based device to form a multichannel codec, and up to eight TLV320AIC2x codecs can be cascaded
to a single serial port.
The TLV320AIC2x 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 I
2C or a simple S2C (start-stop communication protocol).
The TLV320AIC2x integrates all of the critical functions needed for most voice-band applications including MIC
preamplifier, handset amplifier headset amplifier, 8-
speaker driver, sidetone control, antialiasing filter (AAF),
input/output programmable gain amplifier (PGA), and selectable low-pass IIR/FIR filters.
The TLV320AIC2x implements an extensive power management; including device power-down, independent
software control for turning off ADC, DAC, operational-amplifiers, and IIR/FIR filter (bypassable) to maximize
system power conservation. The TLV320AIC2x consumes only 14.9 mW per channel at 3 V.
The TLV320AIC2x 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 TLV320AIC2x is characterized for commercial operation from 0°C to 70°C, and industrial operation from
-40°C to 85°C. The TLV320AIC2xk is characterized for industrial operation from -40°C to 85°C.
