Overview
The TLV320AIC23BPW 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. It operates within a temperature range of -10°C to 70°C.
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.
- Features an analog bypass path allowing stereo-line inputs to connect directly to the headphone amplifier without digital conversion.
Applications
- Portable solid-state audio players
- Digital audio recorders
- MP3 digital audio players
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required industrial or commercial temperature rating. Ensure the datasheet version aligns with current design specifications before finalizing procurement orders.
Selection Notes
Select this model for designs requiring a compact 28-pin TSSOP footprint. Verify that the host system supports the required SPI or 2-wire control protocols. Ensure supply voltage rails match the specified ranges for DVDD, BVDD, and AVDD to maintain optimal signal-to-noise performance.
Part Context
This component belongs to the TLV320AIC23B series of low-power stereo codecs. It serves as a cost-effective analog I/O solution for portable electronics. The TSSOP variant provides a larger board area compared to MicroStar Junior packages but offers standard surface-mount compatibility.
Replacement Considerations
Direct replacements include TLV320AIC23BRHD (28-pin PQFP) or TLV320AIC23BIGQE (32-pin MicroStar Junior). Verify pinout compatibility and package dimensions when substituting these variants.
