LTC1069-6IS8#PBF

Overview

The LTC1069-6IS8#PBF is a single-supply, very low power elliptic lowpass filter manufactured by Analog Devices Inc. It integrates an 8th-order active filter with a clock sweepable architecture, allowing the cutoff frequency to be adjusted via an external clock signal. The device operates on a single supply voltage and is designed for applications requiring high selectivity with minimal power consumption. Key electrical characteristics include a low input noise density and a wide dynamic range, making it suitable for precision signal processing tasks in portable and battery-operated systems.

Feature Summary

• Integrates an 8th-order elliptic lowpass filter response within a single package
• Features a clock-sweepable architecture for adjustable cutoff frequency control
• Designed for single-supply operation to simplify system power requirements
• Optimized for very low power consumption suitable for battery-powered applications

Applications

• Portable medical instrumentation requiring high selectivity and low power
• Battery-operated data acquisition systems
• Precision sensor signal conditioning circuits
• Communication systems requiring adaptive filtering capabilities

Procurement Notes

Verify the specific suffix IS8#PBF against the manufacturer's current datasheet to confirm pinout compatibility and temperature grade. Ensure the external clock source meets the specified frequency range for the desired cutoff performance. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when an 8th-order elliptic response is needed without discrete components. Consider the external clock requirement for cutoff frequency adjustment. Evaluate the power supply constraints to ensure single-supply operation fits the design. Compare noise specifications against other filters if ultra-low noise is critical.

Part Context

This part belongs to the LTC1069 family of clock-sweepable elliptic filters from Analog Devices. It shares architectural similarities with other members like the LTC1069-1 but offers specific filter coefficients optimized for general-purpose lowpass applications. The IS8 package indicates an industrial temperature range and SOIC-8 footprint.

Replacement Considerations

Direct replacements may include other parts from the LTC1069 family such as the LTC1069-1 or LTC1069-4, depending on the required filter order and coefficient set. Verify that alternative devices support the same single-supply voltage range and clock sweep functionality.
