ISPPAC81-01PI

Overview

The ISPPAC81-01PI is a programmable analog filter component from Lattice Semiconductor's ispPAC family, designed for precision signal conditioning. It integrates high-performance analog blocks with digital configuration capabilities to implement custom filter responses without external passive components. The device operates within a specified voltage range and supports various filter topologies suitable for sensor interface applications. Its architecture allows for the suppression of out-of-band noise and resonance, making it effective for enhancing signal integrity in mixed-signal systems.

Feature Summary

• Programmable analog filtering with integrated op-amps and capacitors
• Supports low-pass, high-pass, band-pass, and notch filter configurations
• Digital control interface for real-time tuning and calibration
• Designed for sensor signal conditioning and noise suppression

Applications

• Sensor signal conditioning for industrial and automotive systems
• Out-of-band resonance suppression in measurement circuits
• Anti-aliasing filters for data acquisition systems
• Noise filtering in communication interfaces

Procurement Notes

Verify the specific suffix '01PI' against official Lattice documentation to confirm package type, temperature grade, and tape/reel specifications. Ensure compatibility with the ispPAC-Designer software version used for generating the configuration file. Check for any recent product change notices regarding pinout or electrical characteristics updates.

Selection Notes

Select this component when fixed analog filters lack the flexibility required for varying sensor outputs or environmental conditions. Consider the ISPPAC81-01PI for designs requiring precise cutoff frequency adjustment or multiple filter stages in a single package. Evaluate power supply constraints and available digital control lines before finalizing the design.

Part Context

The ISPPAC81-01PI belongs to the ispPAC81 series, which focuses on compact, programmable analog solutions. This series complements Lattice's FPGA portfolio by providing dedicated analog functionality that reduces board space and component count. It is part of the broader ispPAC family known for integrating analog and digital technologies for system-level optimization.

Replacement Considerations

No direct public substitute part numbers are confirmed for the ISPPAC81-01PI. Alternative solutions may require discrete analog components or different programmable analog devices, necessitating circuit redesign and verification.
