LTC1067-50IS#TRPBF

Overview

The LTC1067-50IS#TRPBF is a dual switched-capacitor filter building block in a 16-lead SSOP package. It contains two identical second-order sections with rail-to-rail input and output operation. The device operates from a single supply ranging from 2.7V to 11V, consuming approximately 1mA at 3.3V. Each section allows for clock-to-center frequency ratios of 50:1, adjustable via external resistors. Center frequency range extends from 0.001kHz to 40kHz. The component provides low noise performance under 40mVRMS for Q less than or equal to 5.

Feature Summary

• Dual second-order switched-capacitor architecture
• Rail-to-rail input and output capability
• Adjustable clock-to-center frequency ratio
• Low power consumption profile

Applications

• Notch filters
• Narrowband bandpass filters
• Tone detection systems
• Noise reduction applications

Procurement Notes

Verify the IS suffix indicates industrial temperature range (-40°C to 85°C) and TRPBF denotes tape and reel packaging. Confirm RoHS compliance status through official documentation before procurement. Ensure the specific lot traceability meets project requirements.

Selection Notes

Select this part when a low-power dual filter solution is required compared to the standard LTC1067. Verify that the 50:1 nominal clock ratio aligns with system timing constraints. Check if the 16-lead SSOP package fits the available PCB footprint and thermal management strategy.

Part Context

This component belongs to the LTC1067 family of universal filter building blocks. It serves as a lower power variant of the LTC1067, maintaining similar functional characteristics while reducing current draw. The series supports various filter topologies including Butterworth and Chebyshev designs.

Replacement Considerations

The LTC1067CGN or LTC1067IGN are functionally compatible but consume higher current. Verify pin compatibility and ensure the different clock-to-frequency ratio does not impact existing circuit designs.
