TLV320AIC22CPTR

Overview

The TLV320AIC22CPTR is a dual VoIP codec manufactured by Texas Instruments, housed in a 48-pin Low-Profile Quad Flat Package (LQFP). It operates within an extended temperature range of -40 °C to +85 °C. The device features a 16-bit linear coding resolution and supports A/Mu-law compression algorithms. It integrates two functional channels with four ADCs and one DAC. The component utilizes serial I2C and SPI interfaces for control and data transmission. Designed for surface-mount installation, it functions at a typical supply voltage of 3.3 V with a sampling rate capability of 16 ksps.

Feature Summary

• Integrated dual-channel architecture supporting simultaneous voice processing tasks
• Supports both linear 16-bit coding and standard A/Mu-law compression formats
• Includes internal filtering capabilities for signal conditioning
• Compatible with standard serial communication protocols for system integration

Applications

• Voice over IP (VoIP) gateway devices
• Dual-line telephone systems
• Conference phone audio processing units

Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest datasheet to ensure authenticity. Confirm that the LQFP-48 footprint matches the target PCB design requirements. Check for RoHS compliance status as indicated in official documentation. Ensure storage conditions adhere to moisture sensitivity level specifications prior to reflow soldering.

Selection Notes

Select this component when a dual-channel solution is required for voice-centric applications. It is suitable for designs needing integrated A/Mu-law conversion without external processors. Consider the 48-pin LQFP package constraints for board space. Verify that the 16-bit resolution and 16 ksps sampling rate meet the specific audio quality requirements of the end product.

Part Context

This part belongs to the TLV320AIC22 series of audio codecs from Texas Instruments. It is specifically engineered for telecommunications equipment requiring high integration. The CPTR suffix indicates the tape-and-reel packaging variant intended for automated assembly processes. It serves as a specialized interface between analog audio signals and digital baseband processors.

Replacement Considerations

Consult the official Texas Instruments substitution guide for verified alternatives. Ensure any replacement maintains the 48-pin LQFP form factor and electrical compatibility.
