LTC1560-1CS8#PBF

Overview

The LTC1560-1CS8#PBF is a fifth-order, continuous-time, lowpass elliptic filter manufactured by Analog Devices Inc. It operates with ±5V supplies and features pin-selectable cutoff frequencies of either 1MHz or 500kHz. The device requires no external components for basic operation and offers a signal-to-noise ratio of up to 75dB. Electrical characteristics include a passband ripple of -0.3dB at the 1MHz setting and stopband attenuation exceeding 60dB. The component is housed in an 8-lead plastic SOIC package.

Feature Summary

• Pin-selectable cutoff frequency configuration between 500kHz and 1MHz
• Elliptic transfer function optimized for antialiasing selectivity
• Integrated shutdown mode for power saving applications

Applications

• Antialiasing filters
• Smoothing or reconstruction filters
• Communication filters

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the CS8 designation corresponds to the commercial temperature range (0°C to 70°C). Ensure the supplier provides original manufacturer documentation to validate authenticity and traceability before procurement.

Selection Notes

Select this component for high-frequency filtering where minimal external parts are required. Consider the 1MHz or 500kHz options based on system bandwidth needs. Evaluate the need for an output buffer if driving loads below 10kΩ to maintain distortion specifications.

Part Context

This part belongs to the LTC1560 family of continuous-time filters. It is designed as a compact solution for high-frequency signal processing tasks. The device integrates the necessary active elements within the SO-8 package to eliminate external passive components typically required for such filter orders.
