LTC1560-1IS8#PBF

Overview

The LTC1560-1IS8#PBF is a fifth-order continuous-time lowpass elliptic filter in an SOIC-8 package. It features pin-selectable cutoff frequencies of 1MHz or 500kHz via Pin 5. The device operates on ±5V supplies with a typical power supply current of 29mA, reducing to 1mA in shutdown mode. Key electrical parameters include a signal-to-noise ratio of 75dB and stopband attenuation exceeding 60dB. The input resistance is typically 10kΩ, and the output can source or sink 1mA.

Feature Summary

• Pin-selectable cutoff frequency configuration for 1MHz or 500kHz operation
• Elliptic transfer function optimized for antialiasing selectivity and transient response
• Integrated shutdown mode for significant power reduction
• Low noise and low distortion performance without external components

Applications

• Antialiasing filters
• Smoothing or reconstruction filters
• Communication filters

Procurement Notes

Verify the specific suffix IS8#PBF against the manufacturer's latest documentation to confirm the industrial temperature range (-40°C to 85°C) and lead-free packaging status. Cross-reference the part number with official Analog Devices databases to ensure compatibility with current production standards and RoHS compliance requirements before procurement.

Selection Notes

Select this component when a compact, high-frequency elliptic filter is required without external passive components. Ensure the application supports dual ±5V supplies or appropriate single-supply biasing. Consider the 10kΩ input impedance and 1mA output drive capability when interfacing with source and load circuits.

Part Context

The LTC1560-1 belongs to a family of continuous-time active filters designed by Linear Technology (now Analog Devices). These devices integrate complex filter functions into small surface-mount packages, eliminating the need for bulky external inductors or precise capacitor matching typically required in discrete RC designs.
