TLV320AIC22CPT

Codecs Overview

The TLV320AIC22CPT is a dual-channel, low-power audio codec manufactured by Texas Instruments. It features two 16-bit analog-to-digital converters and two 16-bit digital-to-analog converters utilizing oversampling sigma-delta technology. The device supports programmable sampling rates up to 26 ksps with filters enabled or 104 ksps when bypassed. It operates on a 2.7-V to 3.6-V analog supply and a 1.65-V to 1.95-V digital core supply. The component is housed in a 48-pin Low-Profile Quad Flat Package (LQFP) and is characterized for industrial operation from -40°C to 85°C.

Codecs Feature Summary

• Integrates stereo 16-bit oversampling sigma-delta A/D and D/A converters with built-in analog functions including programmable gain amplifiers and microphone amplifiers.
• Supports flexible serial communication via the SMARTDM interface for DSP connectivity and a two-wire host port compatible with I2C or S2C protocols.
• Includes selectable FIR/IIR digital filters and analog sidetone control for voice-band signal processing applications.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems

Codecs Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure the procurement source provides valid traceability and authenticity guarantees for integrated circuits. Confirm that the delivered components match the specified industrial grade requirements for the intended operating environment.

Codecs Selection Notes

Select this component for designs requiring a highly integrated dual-channel solution with low power consumption. Verify compatibility with the target processor's serial interface protocol. Ensure the system power supplies align with the specified voltage ranges for analog, digital, and I/O sections to maintain optimal performance.

Codecs Part Context
