LTC1566-1IS8#TRPBF

Overview

The LTC1566-1IS8#TRPBF is a 7th order continuous time lowpass filter with a 2.3MHz cutoff frequency and 12dB passband gain. It features differential inputs and outputs, operating on a single 5V or ±5V supply. The device exhibits an input referred noise of 62µVRMS in a 2MHz bandwidth and achieves 71dB spurious free dynamic range. It provides 40dB attenuation at 1.5 times the cutoff frequency and over 60dB for frequencies above 10MHz. The IS suffix indicates an industrial temperature range of –40°C to 85°C.

Feature Summary

• Differential signal interface simplifies integration with wireless systems
• Adjustable output DC common mode voltage optimizes signal paths
• Requires no external components beyond power supply decoupling

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required specifications. The 'I' designation confirms the industrial temperature range of –40°C to 85°C. The 'S8' indicates the SO-8 package type. The '#TRPBF' suffix specifies tape and reel packaging without halogens. Confirm these details align with system requirements before procurement.

Selection Notes

Select this component when a fixed 2.3MHz cutoff frequency is required for data acquisition or communications. It replaces bulky discrete designs using op amps and passive components. Ensure the application supports differential signaling to utilize its high impedance inputs and adjustable output offsets effectively.

Part Context

This part belongs to the LTC1566 family of continuous time filters. It is designed as a direct replacement for LC filters in specific applications. Other variants exist with different cutoff frequencies or single-ended I/O configurations upon request from the manufacturer.
