TLV320AIC3256IRSBR

Codecs Overview

The TLV320AIC3256IRSBR is a very low-power stereo audio codec manufactured by Texas Instruments. It features two analog-to-digital converters and two digital-to-analog converters with a resolution of 32 bits. The device operates within a supply voltage range of 1.5 V to 1.95 V and supports serial interfaces including I2C and SPI. It achieves a signal-to-noise ratio of 93 dB for the ADC and 100 dB for the DAC, with total harmonic distortion plus noise of -84 dB for the ADC and -81 dB for the DAC. The component functions at conversion rates up to 48 kHz and operates within a temperature range of -40°C to +85°C. It is housed in a WQFN-40 package.

Codecs Feature Summary

• Integrates dual ADCs and dual DACs for stereo audio processing
• Supports standard serial communication protocols for system control
• Designed for ultra-low power consumption in portable applications

Codecs Applications

• Portable multimedia devices requiring high-fidelity audio
• Voice-enabled consumer electronics
• Wearable technology with strict power constraints

Codecs Procurement Notes

Verify the specific suffix IRSBR to confirm the WQFN-40 packaging and reel quantity specifications. Ensure compatibility with the required operating voltage range of 1.5 V to 1.95 V during integration. Confirm moisture sensitivity handling procedures are followed upon receipt. Cross-reference the manufacturer part number against official datasheets to validate performance parameters before finalizing procurement orders.

Codecs Selection Notes

Select this component when a stereo codec with integrated headphone amplifiers and low power requirements is needed. Compare SNR and THD+N specifications against alternative models if higher audio fidelity is required. Consider the WQFN-40 footprint for PCB layout constraints. Verify interface compatibility with the host processor's available serial ports.

Codecs Part Context

This part belongs to the TLV320AIC3256 series of audio codecs from Texas Instruments. It shares core functionality with variants like the TLV320AIC3256IYZFR, differing primarily in packaging type. The series is designed for battery-powered devices where power efficiency and audio quality are critical. It complements other Texas Instruments audio solutions such as amplifiers and DSPs.

Codecs Replacement Considerations

The TLV320AIC3256IYZFR serves as a functional alternative with identical electrical characteristics but utilizes a DSBGA-42 package instead of WQFN-40. Verify pinout compatibility and thermal performance differences before substitution. Other series members may offer different packaging or minor feature variations.
