XE3005I033TRLF

Overview

The XE3005I033TRLF is an ultra low-power audio CODEC manufactured by Semtech Corporation, housed in a 20-pin TSSOP package. It integrates a 16-bit ADC and a 16-bit DAC for voice and audio applications. The device operates on a single supply voltage ranging from 1.8 V to 3.6 V, with a typical current consumption of 0.4 mA at a 20 kHz sampling rate. It supports adjustable sampling frequencies between 4 kHz and 48 kHz. Typical dynamic range performance is specified at 78 dB for both the ADC and DAC channels.

Feature Summary

• Ultra-low power consumption below 2 mW
• Integrated microphone bias and preamplifier
• Class D power amplifier output stage
• Flexible serial audio interface compatibility

Applications

• Wireless headsets
• Bluetooth headsets
• Hands-free telephony systems
• Digital hearing instruments
• Battery-operated portable audio devices

Procurement Notes

Verify the specific ordering suffix I033TRLF against official Semtech documentation to confirm the TSSOP-20 package configuration and commercial temperature range (-20°C to 70°C). Ensure that the lead time and availability align with current distributor schedules, as these factors are subject to change and require real-time verification from authorized suppliers.

Selection Notes

Select this component for designs requiring minimal external components and direct microphone or speaker interfacing. The XE3005 lacks the Sandman™ function found in the XE3006 variant; choose this part if signal presence detection is not required. Ensure the system clock requirements match the MCLK input specifications for proper operation within the 4 kHz to 48 kHz sampling range.

Part Context

This part belongs to the XE3005/XE3006 family of low-power audio CODECs from Semtech. While the XE3006 includes additional Sandman™ functionality for power management based on signal presence, the XE3005 focuses on core conversion capabilities. Both variants share similar electrical characteristics and interface protocols, differing primarily in advanced power-saving features.

Replacement Considerations

The XE3006 serves as a functional substitute if Sandman™ support is needed, though it utilizes a TSSOP-24 package. No other direct pin-compatible replacements are documented in the provided datasheet.
