LTC1563-2CGN#TRPBF

Overview

The LTC1563-2CGN#TRPBF is a fourth-order active RC lowpass filter in a 16-lead SSOP package. It provides a unity-gain Butterworth response using a single external resistor, with cutoff frequencies adjustable from 256Hz to 256kHz via the formula R = 10k(256kHz/fC). The device operates on a single supply of 3V to 11V or dual supplies up to ±5V. Key electrical characteristics include a typical DC offset of ±1mV, power supply current of 8mA to 17mA in high-speed mode, and rail-to-rail input/output voltage swing capabilities.

Feature Summary

• Single-resistor cutoff frequency setting for simplified design
• Rail-to-rail input and output operation
• Low power shutdown mode with near-zero current consumption
• Cascadable architecture for forming higher-order filters

Applications

• Discrete RC active filter replacement
• Antialiasing filters for data acquisition systems
• Smoothing or reconstruction filters
• Linear phase filtering for data communication
• Phase locked loops

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with lead-free compliance. Confirm the CGN variant meets commercial temperature requirements (0°C to 70°C) against application needs. Ensure ordering documentation matches the Analog Devices manufacturer identification for authenticity verification.

Selection Notes

Select this component when a Butterworth response is required without complex resistor networks. Verify that the desired cutoff frequency falls within the 256Hz to 256kHz range for standard operation. Consider the Low Power mode if supply current reduction is critical for lower frequency applications below 25.6kHz.

Part Context

This part belongs to the LTC1563 family of active RC filters. The -2 designation specifies the Butterworth response characteristic, distinguishing it from the -3 variant which offers a Bessel response. Both share identical pinouts and operational principles, differing only in internal capacitor ratios to shape the frequency response.
