LTC1062CN8

Overview

The LTC1062CN8 is a 5th order Butterworth 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 ±2.5V to ±9V. The device provides a maximally flat response and eliminates DC offset and low-frequency noise issues by placing the filter outside the DC path. The cutoff frequency is set by an internal clock that can be externally driven, maintaining a typical clock-to-cutoff frequency ratio of 100:1. It features an internal oscillator, cascading capability for faster rolloff, and an available buffer output.

Feature Summary

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

Applications

Antialiasing Filter
Digital Voltmeters
Strain Gauges

Procurement Notes

Verify the specific package type N8 (8-Lead PDIP) matches your board layout requirements. Confirm the operating temperature range (-40°C to 85°C) aligns with your system specifications. Ensure power supply voltages remain within the specified limits to prevent damage. Check for any obsolescence notices regarding older packages like J8 or M variants if sourcing from secondary markets.

Selection Notes

Select this component when a 5th order Butterworth response is required without DC offset errors. Consider using external capacitors at Pin 5 to adjust the internal oscillator frequency if precise cutoff control is needed. For higher selectivity, cascade two units to form a 10th order filter. Ensure the input signal amplitude does not exceed the feedback node gain limits to avoid clipping.

Part Context

The LTC1062CN8 belongs to the LTC1062 family of switched capacitor filters. It is part of Linear Technology's enhanced LTCMOS silicon gate process technology. Related parts include the LTC1063, which offers clock-tunable operation without external components, and the LTC1065, which provides a Bessel response.
