LTC1064-1CSW#TRPBF

Overview

The LTC1064-1CSW#TRPBF is an 8th-order, clock-sweepable elliptic lowpass switched capacitor filter in a 16-pin SW package. It operates from ±2.37V to ±8V supplies with a maximum corner frequency of 50kHz and a 100:1 clock-to-cutoff ratio. Electrical specifications include 150µVRMS wideband noise, 0.03% THD at 3VRMS input, and stopband attenuation exceeding 68dB at 1.5 times the cutoff frequency. The device requires no external components for frequencies up to 20kHz.

Feature Summary

• Integrated 8th-order elliptic filtering topology without external passive components
• Clock-programmable cutoff frequency with a fixed 100:1 ratio
• Low harmonic distortion and wideband noise performance

Applications

• Antialiasing filters
• Telecom PCM filters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the component matches the Analog Devices Inc. manufacturer identification. Ensure the part number corresponds to the standard operating temperature range unless military variants are explicitly required.

Selection Notes

Select this component for applications requiring high-order filtering in a compact surface-mount footprint. Verify that the system can provide a TTL or CMOS clock signal within the specified voltage thresholds. Ensure power supply decoupling is implemented close to the package pins to maintain stability.

Part Context

This part belongs to the LTC1064 family of switched capacitor filters. It shares pin compatibility with the LTC1064-2 series. The SW package variant provides a 16-lead plastic wide small outline form factor suitable for automated assembly processes.

Replacement Considerations

The LTC1064-2 is pin compatible with this device. Consult Linear Technology Marketing for parts specified with wider operating temperature ranges.
