LTC1069-6CS8#PBF

Overview

The LTC1069-6CS8#PBF is a single-supply, very low power elliptic lowpass filter manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 5.5V and consumes only 300µA of current. The device features an 8th-order progressive elliptic response with a cutoff frequency of 10kHz and provides 60dB of attenuation at 20kHz. It utilizes a clock sweepable architecture for optimal noise performance and includes an internal oscillator that can be synchronized to an external clock. The component is housed in an 8-pin SOIC package.

Feature Summary

• Progressive elliptic filter topology providing steep roll-off characteristics
• Clock sweepable architecture for optimized noise performance
• Internal oscillator with synchronization capability for external clock input
• Single-supply operation compatible with low voltage systems

Applications

• Battery-powered instrumentation requiring low power consumption
• Data acquisition systems needing anti-aliasing filtering
• Medical equipment with strict power constraints
• Portable test and measurement devices

Procurement Notes

Verify the specific suffix CS8 indicates commercial temperature range operation and PBF denotes lead-free packaging. Confirm the manufacturer source matches Analog Devices Inc. documentation. Ensure the part number corresponds to the 10kHz cutoff variant rather than other frequency options in the LTC1069 family. Check RoHS compliance status against current regulatory requirements.

Selection Notes

Select this component when a high-order elliptic response is required with minimal power draw. Compare against other LTC1069 variants if different cutoff frequencies or passband ripple specifications are needed. Consider the need for external clock synchronization versus internal oscillator usage. Evaluate board space requirements against the 8-SOIC package dimensions.

Part Context

This part belongs to the LTC1069 family of switched-capacitor filters. It shares architectural similarities with other members like the LTC1064 but offers distinct elliptic characteristics. The CS8 designation specifies the commercial temperature grade and SOIC-8 package style. It serves as a specialized solution for applications demanding precise analog filtering without complex discrete components.
