TLV320AIC24KIPFB

The TLV320AIC24KIPFB is a low-power stereo Voice-band Codec 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. It 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 codec integrates all of the critical functions needed for most voice-band applications including MIC preamplifier, handset amplifier headset amplifier, 8Ω speaker driver, side tone control, antialiasing filter, input/output programmable gain amplifier (PGA) and selectable low-pass IIR/FIR filters.

• Glueless 4-wire interface to DSP
• Programming mode to allow on-the-fly reconfiguration
• Continuous data transfer mode to minimize bit clock speed
• Support different sampling rate for each device
• 2-wire interface
• Differential and single-ended analog input/output
• Built in analog and digital sidetone
• Built in antialiasing filter (AAF)
• Programmable input and output gain control (PGA)
• Microphone/handset/headset amplifiers
• Green product and no Sb/Br

Warnings

Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
