LTC1067-50IGN#PBF

Overview

The LTC1067-50IGN#PBF 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, supporting single supplies from 3V to 5V or dual supplies up to ±5V. The device features a fixed internal clock-to-center frequency ratio of 50:1. Typical supply current is approximately 1mA at 3.3V. Center frequency range extends from 0.001kHz to 40kHz. Dynamic range exceeds 80dB on a single 3.3V supply.

Feature Summary

• Dual second-order switched-capacitor architecture
• Rail-to-rail input and output operation
• Low power consumption profile
• High precision center frequency tuning

Applications

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

Procurement Notes

Verify the specific suffix IGN#PBF against official Analog Devices documentation to confirm the industrial temperature range and lead-free packaging status. Ensure the ordering information matches the exact part number required for your design specifications.

Selection Notes

Select this component when low power consumption is critical compared to the standard LTC1067. Verify that the 50:1 clock-to-center frequency ratio aligns with your system's clocking constraints. Confirm that the 16-lead SSOP package fits your PCB layout requirements.

Part Context

This part belongs to the LTC1067 family of universal filter building blocks. It shares the same core architecture as the LTC1067 but offers reduced power consumption by utilizing a different internal clock ratio. It is designed for high-precision analog signal processing tasks requiring compact solutions.
