LTC1569CS8-6#PBF

Overview

The LTC1569CS8-6#PBF is a 10th order lowpass filter featuring linear phase and a root raised cosine amplitude response. It operates from single supplies of 3V to 5V or dual supplies of ±5V, consuming 3mA at 3V. The cutoff frequency is set by one external resistor with typical accuracy better than 3.5%. Key electrical parameters include a maximum DC offset of 5mV, 80dB CMRR at DC, and 82dB signal-to-noise ratio at 5V supply. The device supports differential or single-ended inputs and provides attenuation exceeding 80dB at six times the cutoff frequency.

Feature Summary

• Linear phase and root raised cosine response for optimal pulse shaping
• Pin-programmable cutoff frequency using a single external resistor
• Low power operation with internal oscillator and multiple divider settings
• High DC accuracy with minimal output offset voltage

Applications

• Data communications filters for 3V operation
• Linear phase and phase matched filters for I/Q signal processing
• Signal conditioning in data acquisition systems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions remain within specified limits to maintain performance. Review datasheet specifications for environmental compliance and handling requirements before integration into final assemblies.

Selection Notes

Select this component when high-order filtering with linear phase is required in space-constrained designs. The SO-8 package minimizes board area while maintaining performance. Consider the internal oscillator range and divider settings to achieve precise cutoff frequencies without external clock sources. Evaluate power consumption constraints against the available supply voltages.

Part Context

This part belongs to the LTC1569 family of sampled data filters. It shares architectural similarities with other members like the LTC1569IS8-6 but differs in temperature rating and specific cutoff frequency configurations. The CS8 suffix indicates commercial temperature range operation in an SO-8 package.

Replacement Considerations

Direct replacements include the LTC1569IS8-6#TR for industrial temperature range applications. Verify pin compatibility and electrical characteristics match system requirements before substitution.
