TLV320AIC23GQE

Codecs Overview

The TLV320AIC23GQE is a high-performance stereo audio codec manufactured by Texas Instruments, housed in a 32-pin MicroStar Junior package. It integrates sigma-delta ADCs and DACs supporting sample rates from 8 kHz to 96 kHz with word lengths of 16, 20, 24, or 32 bits. The device features an SNR of up to 90 dBA for the ADC and 100 dBA for the DAC at 48 kHz sampling. Operating conditions include an analog supply voltage range of 2.7 V to 3.6 V and a digital core supply of 1.42 V to 3.6 V. The component operates within a temperature range of -10°C to 70°C and includes an integrated headphone amplifier capable of delivering 30 mW into a 32 Ω load.

Codecs Feature Summary

• Integrates multibit sigma-delta modulation technology for both analog-to-digital and digital-to-analog conversion paths.
• Supports software-controlled serial interfaces compatible with SPI and 2-wire protocols for register configuration.
• Includes a complete electret microphone biasing solution with an integrated buffer amplifier and programmable gain stages.
• Provides flexible power management capabilities allowing selective shutdown of internal functions to minimize consumption.

Codecs Applications

• Portable solid-state digital audio players
• Digital voice recorders
• MP3 player systems

Codecs Procurement Notes

Verify the specific ordering suffix GQE to confirm the 32-pin MicroStar Junior package and the commercial temperature range of -10°C to 70°C. Ensure that the design environment supports the required analog and digital supply voltage levels specified in the datasheet. Confirm that the application does not require the extended industrial temperature range, which corresponds to the IGQE variant.

Codecs Selection Notes

Select this component when a compact form factor is required due to its industry-standard smallest package size of 25 mm². It is suitable for designs utilizing TI C54x DSPs or USB interfaces due to optimized oversampling rates. Verify compatibility with the target system's serial interface protocol, as it supports both I2S and McBSP-compatible modes for glueless integration.

Codecs Part Context

The TLV320AIC23GQE belongs to the TLV320AIC23B family of low-power stereo codecs. It shares functional specifications with other variants such as the PW (TSSOP) package but differs in physical footprint and thermal characteristics. The GQE suffix specifically denotes the MicroStar Junior package configuration intended for space-constrained portable electronics.

Codecs Replacement Considerations

For applications requiring an extended operating temperature range, consider the TLV320AIC23IGQE, which maintains the same package but operates from -40°C to 85°C. Other package options within the same family include the TLV320AIC23PW in a 28-pin TSSOP format.
