TLV320AIC3256IYZFT

Codecs Overview

The TLV320AIC3256IYZFT is a low-power stereo audio codec manufactured by Texas Instruments, featuring embedded miniDSP capabilities. It operates within an analog supply voltage range of 1.5 V to 1.95 V and a digital supply voltage range of 1.26 V to 1.95 V. The device supports a maximum sampling rate of 48 kHz with 32-bit resolution. It integrates two ADCs and two DACs, achieving signal-to-noise ratios of 93 dB for the ADC and 100 dB for the DAC. Communication is facilitated via I2C, Serial, or SPI interfaces. The component is housed in a 42-ball DSBGA package measuring 3.75 mm x 3.25 mm and functions reliably across a temperature range of -40°C to +85°C.

Codecs Feature Summary

• Integrates programmable miniDSP for extensive signal processing options including AGC, DRC, and EQ.
• Supports flexible analog inputs including six single-ended or three fully-differential channels, plus stereo analog and digital microphone inputs.
• Features ground-centered stereo headphone outputs and very-low-noise PGA for high-fidelity playback.
• Includes PowerTune technology to optimize power consumption during recording and playback operations.

Codecs Applications

• Portable navigation devices (PND)
• Mobile handsets
• Portable media players (PMP)
• Portable computing devices

Codecs Procurement Notes

Verify the specific suffix 'IYZFT' against the manufacturer's current orderable parts list to ensure availability and correct packaging configuration. Confirm that the 42-DSBGA package dimensions align with the target PCB footprint. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement plans.

Codecs Selection Notes

Select this component when ultra-low power consumption is critical for battery-operated portable electronics. Ensure the system design accommodates the specific 1.5 V to 1.95 V analog supply requirement. Verify that the host processor supports the required I2C or SPI digital interface protocols for codec configuration and data transfer.

Codecs Part Context

This part belongs to the TLV320AIC3256 series of ultra-low power stereo audio codecs. It is distinct from higher-voltage variants like the TLV320AIC3263, which supports up to 5.5 V. The IYZFT designation specifically indicates the industrial temperature grade and the 42-ball DSBGA package type, differentiating it from QFN package alternatives.

Codecs Replacement Considerations

Direct functional substitutes include other members of the TLV320AIC325x family, such as the TLV320AIC3256IYZFR, provided the reel packaging is acceptable. Cross-family replacements require careful evaluation of supply voltage compatibility and package pinout differences.
