TLV320AIC23B Obsolete 96kHz Audio Codec In Stock | Datasheet
The TLV320AIC23B is a low-power stereo audio codec from Texas Instruments. It integrates stereo sigma-delta ADC and DAC functions, microphone bias and amplification, stereo line inputs and outputs, and a 30mW-per-channel headphone amplifier.
The codec supports sample rates from 8kHz to 96kHz and audio word lengths of 16, 20, 24 or 32 bits. Its flexible I²S, left-justified, right-justified and DSP-compatible interfaces made it widely used in portable audio, embedded DSP and industrial audio equipment.
Texas Instruments now classifies TLV320AIC23B as obsolete and confirms that it is no longer in production. DataStorageIC supports RFQs for remaining TLV320AIC23B inventory, subject to prior sale.

Frequently Asked Questions
Is TLV320AIC23B discontinued?
Yes. Texas Instruments classifies TLV320AIC23B as obsolete and confirms that the device is no longer in production.
Does TLV320AIC23B support 96kHz audio?
Yes. The codec supports sampling frequencies from 8kHz to 96kHz and audio word lengths of 16, 20, 24 and 32 bits.
What is the difference between TLV320AIC23BIPW and TLV320AIC23BIPWR?
Both are industrial-temperature 28-pin TSSOP devices rated from −40°C to +85°C. TLV320AIC23BIPW is supplied in tubes, while TLV320AIC23BIPWR is the tape-and-reel version.
Are the TSSOP and VQFN versions interchangeable?
No. They provide the same codec functions but use different package footprints and pin assignments. The PCB layout must match the complete ordering code.
Is TLV320AIC3104 a drop-in replacement?
No. TI lists TLV320AIC3104 as a similar-function replacement, but it uses a different package, pinout, control interface, supply arrangement and register map.
How can I request TLV320AIC23B stock?
Send the complete part number, required quantity, acceptable date code and delivery destination. Do not submit only the base number because TSSOP, VQFN and older MicroStar package variants are not physically interchangeable.
