TLV320AIC23BIPWG4

Codecs Overview

The TLV320AIC23BIPWG4 is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It features multibit sigma-delta ADC and DAC architectures supporting sample rates from 8 kHz to 96 kHz with word lengths of 16, 20, 24, or 32 bits. The device operates with a digital core supply (DVDD) ranging from 1.42 V to 3.6 V and analog/buffer supplies (AVDD/BVDD) from 2.7 V to 3.6 V. Key electrical specifications include an ADC signal-to-noise ratio of up to 90 dBA and a DAC SNR of up to 100 dBA at 48 kHz sampling. It integrates a stereo headphone amplifier capable of delivering 30 mW into 32 Ω loads.

Codecs Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required industrial temperature range (-40°C to 85°C). Ensure the datasheet revision corresponds to the current design requirements before finalizing procurement orders.

Codecs Selection Notes

Select this component when designing portable audio systems requiring low power consumption and high-fidelity stereo conversion. Verify that the host processor supports the required McBSP-compatible serial interface protocols. Ensure the system clock configuration aligns with the supported oversampling rates for optimal digital filter performance.

Codecs Part Context

This part belongs to the TLV320AIC23B family of stereo audio codecs. It shares functional similarities with other variants in the series but is distinguished by its specific 28-pin TSSOP packaging and industrial temperature rating. The 'G4' suffix indicates lead-free construction compliant with RoHS standards.

Codecs Replacement Considerations

Direct replacements within the same package and pinout include the TLV320AIC23BIPW. For different package options, consider the TLV320AIC23BRHD (QFN) or TLV320AIC23BGQE (MicroStar Junior), ensuring voltage and thermal specifications remain compatible.
