XE3005I064TRLF

Overview

The XE3005I064TRLF is an ultra low-power audio CODEC designed for voice and audio applications. It integrates a microphone supply, preamplifier, 16-bit ADC, 16-bit DAC, serial audio interface, power management, and clock management. The device operates on a single supply voltage ranging from 1.8 V to 3.6 V. At a 20 kHz sampling frequency, the current consumption is typically 0.4 mA, with total power consumption below 2 mW. The adjustable sampling frequency ranges from 4 kHz to 48 kHz. Typical dynamic range for both the ADC and DAC is 78 dB. The digital format utilizes 16-bit two's complement data. This specific part number corresponds to the XE3005 variant housed in a uCSP® 20-ball package.

Feature Summary

• Ultra low-power operation suitable for battery-operated portable devices
• Integrated microphone bias sources and programmable pre-amplifier
• Class D power amplifier output for direct speaker connection
• Flexible serial audio interface supporting multiple protocols

Applications

• Wireless headsets
• Bluetooth headsets
• Hands-free telephony systems
• Digital hearing instruments
• Consumer multimedia applications

Procurement Notes

Verify the ordering code XE3005I064TRLF matches the required uCSP® 20-ball package and -20 to 70°C temperature range. Confirm that the XE3005 variant without Sandman™ function meets system requirements. Ensure compatibility with the host processor's SPI and serial audio interface configurations before finalizing procurement.

Selection Notes

Select this component when ultra-low power consumption is critical for portable audio designs. The XE3005 lacks the Sandman™ feature found in the XE3006; choose the XE3006 if signal presence detection is required. Verify that the 78 dB dynamic range suffices for the application. Ensure the host system supports the required 16-bit two's complement digital format and serial interface protocols.

Part Context

The XE3005 is part of Semtech's low-power audio codec portfolio, designed to interface between digital signal processors and analog audio components. It complements the XE3006, which adds Sandman™ functionality. The device simplifies design by integrating necessary analog front-end circuits and a Class D amplifier, reducing the need for external discrete components in compact audio solutions.

Replacement Considerations

The XE3006 serves as a functional alternative if Sandman™ capability is needed. For pin-compatible replacements within the same family, verify package constraints. No other specific substitute part numbers are documented in the provided source material.
