LTC1060CN#PBF

Overview

The LTC1060CN#PBF is a universal dual switched-capacitor filter building block manufactured by Analog Devices Inc. It integrates two high-performance filter sections within a single 20-lead PDIP package, enabling the realization of complex filter topologies using minimal external components. The device supports center frequencies up to 30kHz with ±5V supplies and operates reliably down to ±2.37V. Key electrical characteristics include a guaranteed clock-to-center frequency accuracy of ±0.8% for the standard grade, low DC offset voltages, and a center frequency Q product reaching 1.6MHz. It features TTL and CMOS compatible clock inputs and offers excellent temperature stability for precision analog signal processing applications.

Feature Summary

• Dual integrated switched-capacitor filter blocks allowing cascading for higher-order functions
• TTL and CMOS compatible clock inputs with level shifting capabilities
• Low power consumption suitable for single 5V supply operation
• Pinout compatibility with MF10 for direct replacement in existing designs

Applications

• Telecommunications channel filtering
• Tracking filters for radar and navigation systems
• High-Q bandpass and notch filter implementations
• Instrumentation signal conditioning

Procurement Notes

Verify the specific ordering suffix CN#PBF corresponds to the 20-lead PDIP package and commercial temperature range (-40°C to 85°C). Confirm that the #PBF suffix indicates lead-free and RoHS compliance status as defined by Analog Devices. Ensure the source document explicitly lists this part number as active or obsolete before procurement planning.

Selection Notes

Select the LTC1060CN#PBF when a dual filter architecture is required to minimize board space and component count. Choose this variant over the MJ or AMJ grades if the application operates within the commercial temperature range. Consider the ±0.8% clock-to-center frequency accuracy specification when designing precise tracking filters. Evaluate the maximum clock frequency limits relative to the desired center frequency and Q factor requirements.

Part Context

The LTC1060 belongs to the Linear Technology (now Analog Devices) family of universal dual filter building blocks. It is designed to replace discrete operational amplifier filter stages or other dedicated filter ICs like the MF10. The CN#PBF designation specifically identifies the commercial grade version housed in a plastic dual in-line package, distinguishing it from military or wide-temperature variants.

Replacement Considerations

The datasheet notes pinout compatibility with the MF10. Designers replacing MF10 units should verify supply voltage ranges and clock input levels match the LTC1060 specifications. No other specific substitute part numbers are documented in the provided text.
