Overview
The LTC1063CN8#PBF is a monolithic switched-capacitor filter in an 8-pin PDIP package. It provides a 5th order Butterworth lowpass response with clock-tunable cutoff frequencies up to 50kHz, governed by a 100:1 clock-to-cutoff ratio. The device operates from ±2.375V to ±8V supplies and features a typical output DC offset of 1mV at ±5V. Key electrical parameters include 95µVRMS wideband noise, 50µVRMS clock feedthrough, and 80dB CMRR. It supports internal self-clocking via a single RC or external clock inputs.
Feature Summary
- Monolithic 5th order Butterworth lowpass filter architecture
- Clock-tunable cutoff frequency with 100:1 ratio
- Low DC output offset and high common mode rejection
- Internal oscillator or external clock input capability
Applications
- Anti-aliasing filters
- Strain gauge amplifiers
- Digital voltmeters
- Low level filtering
Procurement Notes
Verify the specific ordering suffix #PBF indicates lead-free compliance when sourcing. Confirm the N8 package designation matches the required 8-pin DIP footprint for your PCB layout. Ensure the component status is active for current production needs.
Selection Notes
Select this part for applications requiring precise DC accuracy and low distortion in a compact form factor. Use the internal oscillator for simple designs with a single RC network. Choose external clocking if synchronization with other system components is necessary. Verify supply voltage ranges match the ±2.375V to ±8V operational limits.
Part Context
The LTC1063 series includes variants such as the LTC1063CSW in a 16-lead SO package and ceramic DIP options. The CN8#PBF specifically denotes the plastic DIP version with lead-free termination. Related parts like the LTC1065 offer Bessel responses for linear phase requirements.
Replacement Considerations
Consider the LTC1063CSW for surface mount applications requiring the same electrical performance. The LTC1065 serves as an alternative if a Bessel filter response is preferred over the Butterworth characteristic.
