LTC1569IS8-6

Overview

The LTC1569IS8-6 is a 10th order lowpass filter featuring linear phase and a root raised cosine amplitude response. It operates from single 3V to –5V supplies with a maximum supply voltage of 11V. The device draws 3mA at 3V and achieves up to 64kHz cutoff frequency. Key electrical parameters include a maximum DC offset of 5mV, 80dB CMRR at DC, and 82dB signal-to-noise ratio at 5V. It accepts differential or single-ended inputs in an SO-8 package.

Feature Summary

• Linear phase and root raised cosine response for optimal pulse shaping
• Pin-programmable cutoff frequency using a single external resistor
• Low power operation with internal oscillator and divider modes
• High DC accuracy with minimal output offset voltage

Applications

• Data communication filters for 3V operation
• Linear phase and phase matched filters for I/Q signal processing
• Pin programmable cutoff frequency lowpass filters

Procurement Notes

Verify the specific suffix IS8-6 against official Analog Devices documentation to confirm industrial temperature range and pinout compatibility. Ensure the ordering information matches the exact package style required for your PCB layout. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a high-order lowpass filter with linear phase is required for data acquisition systems. The internal oscillator simplifies design by requiring only one external resistor for cutoff frequency setting. Consider the divide-by settings to optimize power consumption versus cutoff frequency requirements.

Part Context

This component belongs to the LTC1569 family of sampled data filters. It shares architectural similarities with other members like the LTC1569C but offers extended industrial temperature specifications. The series is designed for applications demanding precise filtering without complex clocking networks.
