LTC1060ACN#PBF

Overview

The LTC1060ACN#PBF is a universal dual switched capacitor filter building block manufactured by Analog Devices Inc. It integrates two high-performance filter sections capable of generating various second-order functions, including lowpass, bandpass, highpass, notch, and allpass configurations. The device operates with supply voltages ranging from ±2.37V to ±8V. Key electrical specifications include a maximum clock frequency of 1.5MHz, a power supply current of 3.5mA at ±5V, and a center frequency range up to 20kHz when the Q factor is less than or equal to 400. The AC grade guarantees a clock-to-center frequency accuracy of ±0.3% and a Q accuracy of ±3%. It features pinout compatibility with the MF10 standard.

Feature Summary

• Dual integrated switched capacitor filter blocks for cascading into fourth-order biquadratic functions
• Guaranteed clock-to-center frequency accuracy over temperature ranges
• TTL and CMOS compatible clock inputs with level shifting capabilities
• Low crosstalk performance between internal filter channels

Applications

• Single 5V medium frequency filter designs
• Very high Q and high dynamic range bandpass filters
• Tracking filters requiring precise frequency response
• Telecom signal processing applications

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. The #PBF designation indicates lead-free compliance. Confirm availability status as distribution channels may vary. Ensure the selected variant matches the required operating temperature range for the intended application environment.

Selection Notes

Select the AC grade variant for tighter guaranteed accuracy specifications regarding clock-to-center frequency ratio and Q factor compared to the standard C grade. Consider the N package for through-hole mounting requirements. Evaluate the supply voltage constraints, as lower supplies reduce the maximum achievable clock frequency and center frequency range.

Part Context

This component belongs to the LTC1060 family of universal dual filter building blocks. It is part of Linear Technology's enhanced LTCMOS silicon gate process lineup, designed to provide low offsets and high dynamic range. The device serves as a versatile active filter solution for analog signal conditioning tasks.

Replacement Considerations

The LTC1060 is pinout compatible with the MF10. Designers replacing legacy MF10 components should verify that the switched capacitor architecture meets the specific bandwidth and noise requirements of the original continuous-time design.
