LTC1560-1IS8#TRPBF

Overview

The LTC1560-1IS8#TRPBF is a fifth-order continuous-time lowpass elliptic filter in an SO-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. It requires no external components for basic operation.

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
• No external passive components required for standard operation

Applications

• Antialiasing filters
• Smoothing or reconstruction filters
• Communication filters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'I' grade designation matches the required industrial temperature range of -40°C to +85°C. Ensure the ordering information aligns with the manufacturer's current production status and lead time requirements.

Selection Notes

Select this component for high-frequency filtering where minimal external parts are desired. The elliptic response provides steep roll-off suitable for antialiasing. Consider the output drive capability limitations when connecting directly to coaxial cables or heavy capacitive loads without buffering.

Part Context

This part belongs to the LTC1560 family of continuous-time filters. It is distinct from other members by its specific fifth-order elliptic topology and dual cutoff frequency options. The IS8#TRPBF variant specifies the industrial temperature range, SO-8 surface mount package, and tape and reel shipping format.

Replacement Considerations

LTC1560-1CS8#TRPBF: Identical electrical performance but specified for commercial temperature range (0°C to 70°C) instead of industrial.
