LTC1562CG-2#TRPBF

Overview

The LTC1562CG-2#TRPBF is a low noise, low distortion continuous time filter with rail-to-rail inputs and outputs, optimized for a center frequency (fO) of 20kHz to 300kHz. It contains four independent 2nd order filter blocks that can be cascaded in any combination. Each block's response is programmed with three external resistors for center frequency, Q and gain. The device operates on a single or dual supply from 4.75V to 10.5V total. It features a 'zero-power' shutdown mode and requires no clock. Typical S/N is 99dB with a -5V supply and 93dB with a single 5V supply.

Feature Summary

• Four independent 2nd order filter sections
• Rail-to-rail input and output voltages
• Resistor-programmable fO, Q, and Gain
• Zero-Power Shutdown Mode

Applications

• High Resolution Systems (14 Bits to 18 Bits)
• Antialiasing/Reconstruction Filters
• Data Communications, Equalizers
• Dual or I-and-Q Channels
• Replacing LC Filter Modules

Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact CG-2 designation to guarantee the correct temperature range and performance characteristics for your design requirements.

Selection Notes

Select the LTC1562CG-2#TRPBF for applications requiring high dynamic range and low distortion without clock synchronization. It is suitable for replacing LC filters or discrete op-amp RC circuits where board space is limited. Consider the 20kHz to 300kHz center frequency optimization when designing for higher frequency ranges compared to the standard LTC1562.

Part Context

This component belongs to the LTC1562 family of universal active filters. The LTC1562-2 variant is specifically optimized for higher center frequencies ranging from 20kHz to 300kHz, unlike the original LTC1562 which targets lower frequencies. It shares the same pinout and block diagram but utilizes different internal R and C values and faster amplifiers to achieve its performance specifications.
