LTC1062CSW#TRPBF

Overview

The LTC1062CSW#TRPBF is a 5th order maximally flat lowpass filter manufactured by Analog Devices Inc. It operates on a single 5V supply or up to ±8V, with a total supply voltage range of 4.75V to 18V. The device provides a cutoff frequency of 1 kHz and supports an input frequency range from DC to 20 kHz. It features a clock-to-cutoff frequency ratio of typically 100:1 and includes an internal buffer. The component is housed in a 16-lead plastic SO (SW) wide package and is designed for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Eliminates DC offset and low-frequency noise issues through an architecture that places the filter outside the DC path.
• Provides a 5th order rolloff using an external RC network coupled via capacitor to an internal switched-capacitor system.
• Supports both internal oscillator generation and external CMOS clock driving for flexible cutoff frequency control.

Applications

• Antialiasing filters
• Digital voltmeters
• Strain gauges

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the manufacturer designation as Analog Devices Inc. matches project requirements. Ensure the 16-lead SW package footprint aligns with PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high DC accuracy without external trimming. The device allows cascading two units to form a 10th order quasi-maximally flat filter. Consider the internal buffer output if buffering is needed, noting it has millivolts of DC offset compared to the DC-accurate output pin.

Part Context

This part belongs to the LTC1062 series of switched-capacitor filters. It utilizes Linear Technology's enhanced LTCMOS silicon gate process. Related parts include the LTC1063, which offers clock-tunable performance without external components, and the LTC1065, which provides a Bessel response.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices marketing for alternate sources or wider operating temperature range variants such as the LTC1062M.
