LTC1066-1CSW#TRPBF

Overview

The LTC1066-1CSW#TRPBF is an 8th-order clock-tunable switched-capacitor lowpass filter in an 18-pin SO Wide package. It provides selectable elliptic or linear phase responses with a maximum cutoff frequency of 120kHz at ±8V supplies. The device features 14-bit DC gain linearity, a maximum DC offset of ±1.5mV, and an input impedance of 500MΩ. It operates from single 5V to ±8V power supplies and drives 1kΩ loads with less than 0.02% THD.

Feature Summary

• Clock-tunable architecture allows adjustment of the cutoff frequency via an external RC network without changing component values.
• Selectable response modes include elliptic for steep roll-off and linear phase for minimal signal distortion.
• High DC accuracy ensures precise signal processing with negligible offset drift over temperature variations.

Applications

• Instrumentation systems requiring high precision filtering
• Data acquisition systems needing anti-aliasing capabilities
• Audio signal processing applications demanding low distortion

Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging and lead-free compliance. Confirm the CSW suffix corresponds to the commercial temperature range (0°C to 70°C). Ensure the order quantity matches the reel specifications provided by the manufacturer.

Selection Notes

Select this component when a tunable 8th-order filter is required. Choose the elliptic mode for sharp attenuation or linear phase for waveform preservation. Ensure the external clock frequency maintains the required 50:1 or 100:1 ratio relative to the desired cutoff frequency.

Part Context

This part belongs to the LTC1066 family of switched-capacitor filters. It shares the core architecture with variants like the LTC1066-2 but differs in specific response characteristics. The CSW designation identifies the plastic wide SOIC package suitable for surface mount assembly.

Replacement Considerations

Public confirmed substitute part numbers are not available in the verified documentation. Evaluate alternative Analog Devices switched-capacitor filters based on pin compatibility and electrical performance requirements.
