TLV320AIC23BIPWRQ1

Codecs Overview

The TLV320AIC23BIPWRQ1 is an automotive-grade stereo audio codec manufactured by Texas Instruments. It integrates a stereo analog-to-digital converter (ADC) and a stereo digital-to-analog converter (DAC) utilizing sigma-delta oversampling technology. The device supports sampling rates from 8 kHz to 96 kHz with data word lengths of 16, 20, 24, or 32 bits. It features an integrated headphone amplifier capable of delivering 30 mW per channel into a 32-ohm load. The ADC provides a signal-to-noise ratio of 90 dB, while the DAC achieves 100 dB. Power consumption is 23 mW in playback mode, with standby power below 150 µW and shutdown power under 15 µW. It operates on dual supplies: 2.7 V to 3.6 V for analog/digital logic and 1.42 V to 3.6 V for the headphone amplifier. The component is housed in a 28-pin TSSOP package and functions within a temperature range of -40°C to +85°C.

Codecs Feature Summary

• Flexible digital interface supporting industry-standard protocols including I2S, Left-Justified, and DSP modes.

Codecs Applications

• In-vehicle infotainment systems requiring robust audio processing.
• Automotive navigation and telematics units.
• Hands-free communication modules in vehicles.
• Digital audio recording devices designed for automotive use.

Codecs Procurement Notes

Verify the specific suffix 'Q1' confirms automotive grade status against the official datasheet. Confirm the 'R' suffix indicates tape-and-reel packaging if reel handling is required. Check RoHS compliance documentation as manufacturing processes may vary. Ensure the source is an authorized distributor to guarantee authenticity. Validate that the part number matches the exact pinout and electrical specifications required for the design.

Codecs Selection Notes

Select this component when automotive reliability is mandatory for audio applications. Compare power consumption metrics against non-automotive alternatives if battery life is critical. Verify compatibility with the host processor's digital audio interface timing requirements. Ensure the supply voltage ranges match the system's available power rails. Consider the TSSOP-28 package dimensions for PCB layout constraints.

Codecs Part Context

This part belongs to the TLV320AIC23B family of low-power stereo codecs. The 'Q1' designation specifically denotes automotive qualification, distinguishing it from commercial variants like the TLV320AIC23BIPW. It shares core functional blocks with the broader series but adheres to stricter automotive testing and quality standards defined by Texas Instruments.

Codecs Replacement Considerations

The TLV320AIC23BIPW is the commercial equivalent without automotive qualification. The TLV320AIC23BIPWG4 is the lead-free commercial version. Direct pin-compatible replacements must be verified against the latest TI substitution guide to ensure electrical and thermal compatibility.
