TLV320AIC33IGQE

Codecs Overview

The TLV320AIC33IGQE is a low-power stereo audio codec manufactured by Texas Instruments, designed for portable applications. It features two analog-to-digital converters and two digital-to-analog converters with a resolution of 24 bits. The device supports sampling rates up to 96 kHz and operates within a supply voltage range of 2.7 V to 3.6 V. Communication is handled via I2C or SPI serial interfaces. It achieves a signal-to-noise ratio of 92 dB for ADCs and 100 dB for DACs, with total harmonic distortion plus noise specified at -90 dB for ADCs and -93 dB for DACs. The component is housed in an 80-pin Microstar Junior BGA package.

Codecs Feature Summary

Codecs Procurement Notes

Verify the specific suffix IGQE against current manufacturer documentation to confirm pinout and packaging compatibility. Confirm RoHS status and REACH SVHC details prior to integration. Check for obsolescence notices as this variant may be discontinued. Ensure supply chain sources provide valid traceability documents for export compliance if applicable.

Codecs Selection Notes

Select this component when a stereo codec with integrated output drivers is required for battery-powered systems. Compare performance metrics such as SNR and THD against alternative models like the TLV320AIC33IGVX if different packaging is needed. Evaluate power consumption requirements against the 2.7 V to 3.6 V operating range. Consider the 80-pin BGA footprint constraints during PCB layout design.

Codecs Part Context

This part belongs to the TLV320AIC33 series of low-power audio codecs from Texas Instruments. It shares core functionality with variants like the TLV320AIC33IGVX but differs in package type and potentially manufacturing lot specifications. The series is engineered for mobile consumer electronics requiring compact form factors and efficient power management.

Codecs Replacement Considerations

The TLV320AIC33IGVX serves as a primary alternative within the same family, offering similar electrical characteristics in a different package configuration. Verify pin-to-pin compatibility and software register settings before substitution. Other series members may require hardware modifications due to differing pin counts or voltage domains.
