TLV320AIC23BIPWR

Codecs Overview

The TLV320AIC23BIPWR is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 28-pin TSSOP package. It features multibit sigma-delta ADCs and DACs supporting data word lengths of 16, 20, 24, and 32 bits with sampling rates from 8 kHz to 96 kHz. The device operates with an analog supply voltage (AVDD) ranging from 2.7 V to 3.6 V and a digital core supply (DVDD) from 1.42 V to 3.6 V. It provides a signal-to-noise ratio of up to 90 dB for the ADC and 100 dB for the DAC at 48 kHz. The component includes a stereo headphone amplifier capable of delivering 30 mW into 32 Ω and supports both SPI and 2-wire control interfaces.

Codecs Feature Summary

• Integrates highly efficient linear headphone amplifiers with analog volume control and mute capabilities.
• Features complete electret microphone biasing and buffering solutions with tunable gain.
• Supports software-controlled flexible power management for extended battery life in portable applications.

Codecs Applications

• Portable solid-state audio players
• Digital audio recorders
• MP3 digital audio players

Codecs Procurement Notes

Verify the specific suffix IPWR confirms the industrial temperature range (-40°C to 85°C) and TSSOP-28 packaging against current manufacturer documentation. Confirm availability status as this product line may be discontinued or superseded by newer revisions. Ensure the ordering information matches the required operating conditions for your target application environment.

Codecs Selection Notes

Select this component when designing portable audio systems requiring low power consumption and high-fidelity stereo conversion. Ensure the host processor supports either SPI or 2-wire serial protocols for configuration. Verify that the system clock requirements align with the internal oscillator capabilities for standard oversampling rates or DSP-specific modes.

Codecs Part Context

This part belongs to the TLV320AIC23B family of low-power stereo codecs. The IPWR suffix specifically denotes the industrial temperature grade variant packaged in a 28-pin Thin Shrink Small Outline Package (TSSOP). This distinguishes it from commercial grade versions and alternative physical packages like MicroStar Junior or PQFP.

Codecs Replacement Considerations

Consult the official TI datasheet for direct pin-compatible alternatives within the same family. Verify if newer revisions offer updated performance metrics or package options suitable for modern designs.
