LTC1566-1CS8#PBF

Overview

The LTC1566-1CS8#PBF 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 parameters include a cutoff frequency accuracy of 5%, input referred noise of 62µVRMS (2MHz bandwidth), and output DC offset of ±10mV maximum. Supply current ranges from 24mA to 34mA depending on the voltage configuration.

Feature Summary

• Differential inputs and outputs simplify interfacing for wireless systems
• Adjustable output DC common mode voltage optimizes signal paths
• Requires no external components for operation
• Low offset voltage minimizes calibration requirements

Applications

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

Procurement Notes

Verify the specific suffix 'CS8' confirms the commercial temperature range and SO-8 package type. Ensure the '#PBF' designation indicates lead-free compliance and RoHS adherence as per manufacturer standards. Confirm that the ordering information matches the exact pinout and marking requirements for the intended PCB layout.

Selection Notes

Select this component when a fixed 2.3MHz cutoff frequency with high linearity is required. The differential architecture is suitable for driving ADCs or modulators directly. Consider the power supply flexibility for integration into existing single or dual rail designs without additional level shifting circuitry.

Part Context
