TLV320AIC33IZXHR

Codecs Overview

The TLV320AIC33IZXHR is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable and battery-operated applications. It features two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs), supporting resolutions up to 24 bits with sampling rates of 96 kHz. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports serial interfaces including I2C and SPI. It provides high audio performance with an SNR of 92 dB for ADCs and 100 dB for DACs, alongside THD+N specifications of -90 dB for ADCs and -93 dB for DACs. The component is housed in an NFBGA-80 package suitable for surface mount technology.

Codecs Feature Summary

Codecs Procurement Notes

Verify the specific suffix 'IZXHR' against official Texas Instruments documentation to confirm the exact package type, tape-and-reel quantity, and moisture sensitivity level. Ensure compatibility with existing PCB footprints for the NFBGA-80 configuration. Cross-reference the datasheet revision history to validate electrical characteristics and pin assignments before finalizing procurement orders.

Codecs Selection Notes

Select this component when a balance between power efficiency and high audio quality is required for stereo applications. The 24-bit resolution and 96 kHz sampling rate support standard CD-quality audio formats. Consider the NFBGA-80 package size constraints and thermal requirements during the design phase. Verify that the host processor supports the necessary I2C or SPI clock speeds for reliable data transmission.

Codecs Part Context

This part belongs to the TLV320AIC33 series of low-power stereo codecs from Texas Instruments. The series is engineered for consumer electronics where space and power consumption are critical factors. Variants within the family may differ in package options such as VQFN or BGA, but share core audio processing architectures. The IZXHR designation specifically indicates the NFBGA-80 packaging format intended for automated surface-mount assembly processes.

Codecs Replacement Considerations

Direct replacements include other members of the TLV320AIC33 family with compatible packages, such as TLV320AIC33IGVX. Evaluate alternative codecs like the TLV320AIC3106 if lower power consumption or different input configurations are acceptable. Ensure any substitute maintains the same interface protocol and voltage levels to avoid redesigning the control logic.
