LTC1060CSW#TRPBF

Overview

The LTC1060CSW#TRPBF is a universal dual switched-capacitor filter building block manufactured by Analog Devices Inc. in a 20-lead plastic SO Wide (SW) package. It integrates two high-performance filter sections capable of realizing various second-order functions, including lowpass, bandpass, highpass, notch, and allpass configurations. The device operates on supply voltages ranging from ±2.37V to ±8V. Key electrical specifications include a maximum clock frequency of 1.5MHz, a center frequency range up to 20kHz with Q ≤ 400, and guaranteed clock-to-center frequency accuracy of ±0.8% for the standard grade. Power consumption is typically 12mA at ±5V supplies.

Feature Summary

• Integrates two independent switched-capacitor filter blocks within a single monolithic IC
• Capable of generating multiple classical filter responses such as Butterworth, Chebyshev, and Bessel
• Features TTL and CMOS compatible clock inputs with integrated level shifting
• Provides pinout compatibility with MF10 devices for direct replacement

Applications

• Single 5V medium frequency filter designs
• High Q and high dynamic range bandpass or notch filters
• Tracking filters and telecom signal processing
• Cascaded fourth-order full biquadratic filter implementations

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the CSW designation corresponds to the 20-lead plastic SO Wide package variant. Ensure the selected temperature grade meets the operational requirements, as the C suffix denotes commercial range operation between -40°C and +85°C.

Selection Notes

Select this component when designing circuits requiring dual filter channels without occupying separate board space. Consider the ±0.8% clock-to-center frequency accuracy if precise tuning is critical. Evaluate the f0 x Q product limits based on the intended clock frequency and desired quality factor to ensure stable operation within the specified gain bandwidth constraints.

Part Context

This part belongs to the LTC1060 family of universal dual filter building blocks. It shares functional similarities with other members like the LTC1060CN and LTC1060ACJ but differs in package type and temperature rating. The SW package variant offers a surface-mount solution suitable for automated assembly processes while maintaining the same internal architecture as through-hole versions.

Replacement Considerations

The LTC1060CSW is pinout compatible with the MF10. Direct replacements include other LTC1060 variants such as the LTC1060CN or LTC1060ACJ, provided the package style and operating temperature range are acceptable for the target application.
