LTC1562CG#TRPBF

Overview

The LTC1562CG#TRPBF is a low noise, low distortion continuous-time active RC quad universal filter manufactured by Analog Devices Inc. It features four independent second-order filter sections housed in a 20-lead SSOP package. The device operates on a total supply voltage ranging from 4.75V to 10.5V and supports center frequencies between 10kHz and 150kHz. It provides rail-to-rail input and output capabilities with a typical DC offset accuracy of 3mV. Key electrical specifications include a typical signal-to-noise ratio of 103dB at –5V supply for Q=1, and a shutdown mode that minimizes power consumption.

Feature Summary

• Continuous-time architecture requiring no external clock signals
• Four independent second-order filter blocks configurable for various response shapes
• Rail-to-rail input and output voltage swing capability
• Resistor-programmable center frequency, quality factor, and gain

Applications

• High resolution systems (14 bits to 18 bits)
• Antialiasing and reconstruction filters
• Data communications and equalizers
• Dual or I-and-Q channels using two matched fourth-order filters
• Linear phase filtering applications

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer designation as Analog Devices Inc. matches the required supply chain standards. Ensure the component grade corresponds to the C temperature range specifications defined in the official datasheet documentation.

Selection Notes

Select this component for designs requiring precise analog filtering without digital clock interference. The internal precision components simplify design by reducing external resistor requirements. Consider the available response types including lowpass, bandpass, and highpass configurations when defining circuit topology.

Part Context

This part belongs to the LTC1562 series of very low noise active RC filters. It serves as a versatile building block for complex filter networks where cascading multiple second-order sections creates higher-order responses such as eighth-order Butterworth filters.
