LTC1067-50CGN#PBF

Overview

The LTC1067-50CGN#PBF is a dual, rail-to-rail, very low noise universal switched-capacitor filter building block manufactured by Analog Devices Inc. It integrates two identical second-order sections within a 16-lead narrow SSOP package. The device operates from a single supply ranging from 3V to 11V or a dual supply of ±5V. It features a fixed internal clock-to-center frequency ratio of 50:1 and an internal sampling-to-center frequency ratio of 100:1. Typical power consumption is approximately 1mA at 3.3V, making it suitable for low-power applications.

Feature Summary

• Dual second-order switched-capaculator architecture providing high accuracy and wide dynamic range
• Rail-to-rail input and output operation compatible with single or dual power supplies
• Low power consumption optimized for battery-operated systems
• Double sampled architecture that places aliasing and imaging components at twice the clock frequency

Applications

• Notch filters for interference rejection
• Narrowband bandpass filters for signal selection
• Tone detection circuits
• Noise reduction systems

Procurement Notes

Verify the specific suffix CGN against official documentation to confirm the package type and temperature rating. Ensure the ordering information matches the exact component requirements for your design.

Selection Notes

Select this component when a low-power, dual-channel switched-capacitor filter is required. The 50:1 clock ratio distinguishes it from the standard LTC1067. Verify that the center frequency range up to 40kHz meets system specifications.

Part Context

This part belongs to the LTC1067 family of universal filter building blocks. It shares architectural similarities with the LTC1067 but offers reduced power consumption and a different clock-to-center frequency ratio. It is designed for flexible filter configurations using external resistors.

Replacement Considerations

LTC1067CGN#PBF serves as a functional alternative with a 100:1 clock ratio and higher power consumption. Other members of the LTC1067 family may be considered based on specific clock ratio and power requirements.
