LTC1562CN#PBF

Overview

The LTC1562CN#PBF is a low noise, low distortion continuous-time active filter manufactured by Analog Devices Inc. It features four independent second-order filter blocks capable of center frequencies from 10kHz to 150kHz. The device operates on a single or dual supply ranging from 4.75V to 10.5V total. Key electrical specifications include a typical wideband signal-to-noise ratio of 97dB with a single 5V supply and a typical DC offset magnitude of 3mV. The component is housed in a 16-lead PDIP package.

Feature Summary

• Continuous-time architecture requiring no external clock signals
• Rail-to-rail input and output voltage capabilities
• Resistor-programmable center frequency, Q factor, and gain
• Zero-power shutdown mode for power conservation

Applications

• High resolution data acquisition systems (14 bits to 18 bits)
• Antialiasing and reconstruction filters
• Data communications and equalizers
• Dual or I-and-Q channel filtering applications

Procurement Notes

Verify the specific suffix CN#PBF against current manufacturer documentation to confirm lead-free compliance and package type. Confirm availability status as distribution channels may list discontinued variants. Ensure the ordering information matches the required operating temperature range and pinout configuration for the target PCB design.

Selection Notes

Select this component when designing circuits requiring precise analog filtering without digital clock interference. Verify that the required center frequency falls within the 10kHz to 150kHz operational range. Ensure the application can accommodate the necessary external resistors for programming Q and gain parameters while maintaining appropriate load conditions for optimal distortion performance.

Part Context

This part belongs to the LTC1562 family of universal active filters. It serves as a monolithic alternative to discrete op-amp RC networks or LC modules. The CN#PBF designation specifically identifies the PDIP package variant, distinguishing it from surface mount options like the SSOP package found in other family members.
