LTC1067-50CGN#TRPBF

Overview

The LTC1067-50CGN#TRPBF is a dual switched-capacitor filter building block in a 16-lead SSOP package. It operates from a single 3V to –5V supply with a typical current of 1mA at 3.3V. The device provides two identical second-order sections with a clock-to-center frequency ratio of 50:1. Center frequencies range from 0.001kHz to 40kHz, and the input frequency range extends up to 1MHz. Dynamic range exceeds 80dB on a single 3.3V supply, with noise typically below 40mVRMS for Q values less than or equal to 5.

Feature Summary

• Rail-to-rail input and output operation
• Low power consumption compared to standard versions
• High precision center frequency tuning via external clock
• Double sampled architecture for aliasing reduction

Applications

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

Procurement Notes

Verify the CGN suffix indicates the commercial temperature grade (0°C to 70°C) and SSOP-16 package. Confirm the TRPBF designation includes tape and reel packaging and lead-free status. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure compatibility with specific design requirements.

Selection Notes

Select this component when low power consumption is critical, as it draws approximately half the current of the LTC1067. Choose the 50:1 clock-to-center frequency ratio if higher speed filtering is required relative to the clock source. Ensure the application fits within the 0°C to 70°C operating temperature range specified for the C grade.

Part Context

This component belongs to the LTC1067 family of universal dual filter building blocks. It shares the same rail-to-rail architecture and pinout as the standard LTC1067 but is optimized for lower power usage. The primary distinction lies in the internal clock scaling factor and reduced supply current requirements.

Replacement Considerations

LTC1067CGN#TRPBF serves as the higher-power alternative within the same package and feature set.
