LTC1069-6IS8#TRPBF

Overview

The LTC1069-6IS8#TRPBF is a precision, low-power, 10th-order active filter manufactured by Analog Devices Inc. It utilizes switched-capacitor technology to provide linear phase response and high DC accuracy without requiring external capacitors or inductors. The device operates from a single supply voltage ranging from 2.7V to 5.5V and draws a typical supply current of 300µA. It features a fixed cutoff frequency of 64kHz and is housed in an 8-pin SOIC package. This component is designed for applications demanding high selectivity and minimal board space in battery-powered systems.

Feature Summary

• Integrated 10th-order low-pass filtering capability within a compact surface-mount package
• Switched-capacitor architecture eliminates the need for external timing components
• Linear phase response ensures signal integrity with minimal group delay distortion
• Low power consumption suitable for portable and battery-operated equipment

Applications

• Precision sensor signal conditioning
• Anti-aliasing filters in data acquisition systems
• Audio processing circuits requiring linear phase characteristics
• Medical instrumentation front-end filtering

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the IS8 variant corresponds to the industrial temperature range and SOIC-8 package dimensions required for your PCB layout. Ensure compatibility with your system's supply voltage limits before procurement.

Selection Notes

Select this component when a high-order filter response is needed without external passive components. Consider the 64kHz fixed cutoff frequency against your signal bandwidth requirements. Evaluate the 300µA supply current against your total power budget for battery life estimation.

Part Context

This part belongs to the LTC1069 family of switched-capacitor filters. It shares architectural similarities with other members like the LTC1569 but offers different order and cutoff specifications. The IS8 designation identifies the specific package and temperature grade within the broader Analog Devices portfolio.

Replacement Considerations

Direct replacements may include other LTC1069 variants with different cutoff frequencies or orders. Verify pinout compatibility and electrical parameters such as supply current and input impedance before substituting.
