LTC1565-31IS8#TRPBF

Overview

The LTC1565-31IS8#TRPBF is a 7th-order continuous-time linear phase lowpass filter in an 8-lead plastic SO package. It operates on a single 5V or ±5V supply with a cutoff frequency of 650kHz and 5% accuracy. The device features differential inputs and outputs, achieving a spurious-free dynamic range of 75dB and a maximum signal-to-noise ratio of 78dB. Power consumption is typically 24mA at 5V, dropping to less than 10μA in shutdown mode. It requires no external components or clock signals.

Feature Summary

• Provides high selectivity with linear phase response in the passband
• Features fully differential inputs and outputs for wireless system interfacing
• Includes a shutdown mode for significant power reduction
• Operates without external components or clock signals

Applications

• CDMA Basestations
• Data Communications
• Antialiasing Filters
• Smoothing or Reconstruction Filters
• Matched Filter Pairs

Procurement Notes

Verify the IS8 suffix indicates the industrial temperature range (-40°C to +85°C). Confirm the #TRPBF designation ensures lead-free finish and tape-and-reel packaging. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct component revision.

Selection Notes

Select this component when a 7th-order linear phase response is required without external tuning components. Ensure the 650kHz cutoff aligns with system bandwidth needs. Verify that the differential I/O matches the interface requirements of the connected ADC or DAC stages.

Part Context

This part belongs to the LTC1565 family of continuous-time filters. It serves as a replacement for bulky LC filters in data acquisition systems. Other variants include the CS8 version for commercial temperatures and different cutoff frequencies within the series.
