LTC1062CSW#PBF

Overview

The LTC1062CSW#PBF is a 5th order maximally flat lowpass filter manufactured by Analog Devices Inc. in a 16-lead SO-Wide package. It operates on a single 5V supply or up to ±8V, with a total supply voltage range of 4.75V to 18V. The device features no DC error and low passband noise, making it suitable for applications requiring high DC accuracy. The cutoff frequency is set by an internal clock that can be externally driven, with a typical clock-to-cutoff frequency ratio of 100:1. The filter input and output are simultaneously taken across an external resistor, coupled through an external capacitor.

Feature Summary

• Operates DC to 20kHz with no DC error
• Low passband noise performance
• Internal or external clock options
• Cascadable for faster rolloff

Applications

• 60Hz Lowpass Filters
• Antialiasing Filter
• Low Level Filtering
• Rolling Off AC Signals from High DC Voltages
• Digital Voltmeters

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking and datasheet specifications. Ensure the ordering suffix matches the required package type and temperature range. Confirm RoHS compliance status as per the latest documentation. Cross-reference the part number with official distributor catalogs to ensure availability and correct sourcing channels.

Selection Notes

Select this component when a 5th order Butterworth lowpass filter with no DC error is required. Consider the operating temperature range and supply voltage requirements. Evaluate the need for internal or external clock driving based on system design constraints. Check if cascading multiple units is necessary for higher order filtering requirements.

Part Context

The LTC1062 is part of Analog Devices' switched capacitor filter family. It is designed for applications requiring precise lowpass filtering without DC offset issues. The device utilizes Linear Technology's enhanced LTCMOS silicon gate process for manufacturing. Related parts include the LTC1063 and LTC1065, which offer similar functionality with different filter characteristics.

Replacement Considerations

Consider the LTC1063 for a clock-tunable 5th order Butterworth lowpass filter with no external components required. The LTC1065 offers a 5th order Bessel lowpass filter with similar DC accuracy. For higher order filtering, evaluate the LTC1066-1, an 8th order elliptic or linear phase filter.
