TLV320AIC23BIPW

Codecs Overview

The TLV320AIC23BIPW is a stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It supports sampling rates from 8 kHz to 96 kHz with data word lengths of 16, 20, 24, and 32 bits. The device features a third-order multibit sigma-delta ADC with up to 90-dBA SNR and a second-order multibit DAC with up to 100-dBA SNR at 48 kHz. Power supplies include DVDD (1.42 V to 3.6 V), BVDD (2.7 V to 3.6 V), and AVDD/HPVDD (2.7 V to 3.6 V). Playback power consumption is less than 23 mW, standby is under 150 µW, and power-down is under 15 µW.

Codecs Feature Summary

• Integrates highly efficient linear headphone amplifiers capable of delivering 30 mW per channel into 32 Ω loads.
• Includes complete electret microphone biasing and buffering solutions with tunable fixed gain and programmable boost.
• Supports software control via SPI or 2-wire compatible serial protocols for flexible configuration.
• Features an analog bypass path allowing direct connection of stereo-line inputs to the headphone amplifier.

Codecs Applications

• Portable digital audio players
• Digital audio recorders
• Integrated FM tuner designs

Codecs Procurement Notes

Verify component authenticity through authorized distributors or TI directly. Confirm the specific ordering suffix matches the required industrial temperature range (-40°C to 85°C) and package type. Review the latest datasheet revision for any updates to electrical characteristics or pin configurations before finalizing procurement orders.

Codecs Selection Notes

Select this model when a compact stereo codec with integrated headphone drivers is required. Ensure the host system voltage levels are compatible with the specified DVDD and AVDD ranges. Verify that the available clock sources can support the desired oversampling rates for optimal filter performance.

Codecs Part Context

This component belongs to the TLV320AIC23B family of low-power stereo codecs. It is designed as a cost-effective, space-saving solution for portable audio applications. The IPW suffix specifically denotes the 28-pin Thin Shrink Small Outline Package (TSSOP) variant suitable for surface-mount assembly.

Codecs Replacement Considerations

Direct replacements within the same package and specifications include TLV320AIC23BPWG4. Other variants like TLV320AIC23BRHD offer different packaging but share core functionality. Always verify pin compatibility and thermal requirements when substituting.
