LTC1566-1CS8#TRPBF

Overview

The LTC1566-1CS8#TRPBF is a 7th order continuous time lowpass filter with 12dB passband gain, housed in an 8-lead plastic SO package. It operates on a single 5V or ±5V supply within a commercial temperature range of 0°C to 70°C. The device features differential inputs and outputs, requiring no external components. Key electrical specifications include a cutoff frequency accuracy of 5%, 40dB attenuation at 1.5 times the cutoff frequency, and 60dB attenuation above 10MHz. Input referred noise is 62µVRMS in a 2MHz bandwidth, with a typical output DC offset of 3mV and maximum of 10mV.

Feature Summary

• Differential input and output architecture for simplified wireless system interfacing
• Adjustable output DC common mode voltage and offset for signal path optimization
• High impedance inputs compatible with differential demodulators or D/A converters
• Internal 7th order filter network eliminating the need for external passive components

Applications

• WCDMA Basestations
• Communication Filters
• Antialiasing Filters
• Smoothing or Reconstruction Filters
• Matched Filter Pairs

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the CS designation aligns with the required 0°C to 70°C operating temperature range for your application environment. Ensure the 8-lead SO package dimensions match your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a fixed 2.3MHz cutoff frequency with high linearity and dynamic range. Consider the IS variant if operation below 0°C or above 70°C is necessary. Verify that the 12dB internal gain suits your system budget without requiring additional amplification stages.

Part Context

This part belongs to the LTC1566 family of continuous time filters designed for data communications and acquisition systems.
