LTC1061CN#PBF

Overview

The LTC1061CN#PBF is a high-performance triple universal filter building block housed in a 20-lead plastic DIP package. It integrates three independent switched-capacitor filter sections capable of producing various second-order functions, including lowpass, bandpass, highpass, notch, and allpass responses. The device operates from single or dual supplies ranging from –2.37V to –9V. Center frequencies are clock-tunable, typically ranging from 0.1Hz to 35kHz depending on the Q factor and operating mode. It features guaranteed center frequency and Q accuracy over temperature, with a typical signal-to-noise ratio of 90dB.

Feature Summary

• Integrates three universal filter building blocks within a single package for compact design
• Supports up to sixth-order filter functions through cascading configurations
• Features clock inputs compatible with both T2L logic and CMOS standards
• Provides guaranteed center frequency and Q accuracy across the full operating temperature range

Applications

• Tracking filters requiring tunable center frequencies
• Antialiasing filters for data acquisition systems
• High-order bandpass, lowpass, and notch filter implementations

Procurement Notes

Verify that the component matches the specific Analog Devices Inc. part number LTC1061CN#PBF. Confirm the package type is the 20-lead plastic DIP (N Package). Ensure the suffix #PBF indicates lead-free compliance as specified in the manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a triple filter solution is required to minimize board space. Consider the maximum clock frequency limits based on the desired center frequency and Q factor. Verify supply voltage compatibility, as operation below –5V restricts the input frequency range. Check if the plastic DIP package meets the thermal and mechanical requirements of the target application.

Part Context

The LTC1061CN#PBF belongs to the LTC1061 family of universal filter building blocks. It is functionally related to the LTC1059 single filter and the LTC1060 dual filter, allowing for higher-order realization through cascading. The CN variant specifically denotes the commercial temperature range version packaged in a 20-lead plastic DIP.
