LTC1164-6CN#PBF

Overview

The LTC1164-6CN#PBF is a low-power, eighth-order active filter manufactured by Linear Technology. It features pin-selectable elliptic or linear phase (Bessel) response characteristics within a single package. The device operates with a cutoff frequency range from 1 kHz to 30 kHz, determined by an external clock input. It supports supply voltages down to -2.375V for the negative rail and includes internal clock tuning capabilities. Packaged in a 14-DIP format, it integrates multiple filter stages to provide high attenuation without requiring external passive components.

Feature Summary

• Pin-selectable configuration allows switching between elliptic and linear phase responses
• Integrated eighth-order filtering eliminates need for external passive components
• Clock-tunable operation enables precise cutoff frequency adjustment via external signal

Applications

• Precision instrumentation signal conditioning
• Anti-aliasing filters in data acquisition systems
• Audio processing circuits requiring specific phase characteristics

Procurement Notes

Verify that the component matches the exact part number LTC1164-6CN#PBF, noting the CN suffix indicates a DIP package. Confirm the presence of the #PBF designation to ensure lead-free compliance. Check manufacturer documentation for specific handling requirements regarding the analog interface and power supply connections.

Selection Notes

Select this component when an eighth-order lowpass filter is required with selectable response characteristics. It is suitable for applications needing tight control over cutoff frequency through clock tuning. Consider the DIP package constraint if board space allows, as surface mount alternatives exist with different suffixes.

Part Context

This part belongs to the LTC1164 family of low-power active filters. The family offers various order options and package types. The CN variant specifically denotes the dual-in-line package configuration, distinguishing it from surface-mount versions like the SW suffix. It serves as a complete solution for complex filtering tasks in compact designs.

Replacement Considerations

Direct substitutes include other parts within the LTC1164 family such as the LTC1164-6CSW#PBF for surface mount applications. Verify pin compatibility and electrical specifications before substitution. Cross-reference with Analog Devices documentation for equivalent performance metrics.
