LT1567IMS8#PBF

Overview

The LT1567IMS8#PBF is a low-noise, high-speed analog building block optimized for filter applications up to 5MHz. It integrates two wideband rail-to-rail operational amplifiers, with one internally configured as a unity-gain inverter. The device operates on a total supply voltage of 2.7V to 12V and features an input voltage noise density of 1.4nV/√Hz at 100kHz. It provides a gain-bandwidth product of 180MHz and supports signal-to-noise ratios exceeding 100dB. The component is housed in an 8-lead MSOP package.

Feature Summary

• Integrates two wideband op amps with one dedicated unity-gain inverter for differential output generation
• Provides single-ended to differential conversion capability for direct driving of ADCs
• Optimized for low noise performance with minimal wideband noise characteristics
• Supports flexible second-order filter configurations without external clocking

Applications

• Antialiasing or reconstruction filtering in high-speed data communications
• Communication channel or roofing filters
• Video signal processing
• Low noise differential circuits for baseband signal conditioning

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the IMS8 designation corresponds to the 8-lead MSOP surface mount package. Ensure the temperature grade matches the required operating range for the application environment.

Selection Notes

Select this component for designs requiring megahertz-range continuous time filtering with strict noise constraints. The internal inverter simplifies differential circuit topologies compared to using discrete dual op amps. Consider the 180MHz bandwidth when designing for cutoff frequencies approaching the 5MHz limit.

Part Context

This part belongs to the LT1567 family of active filter building blocks. It is distinct from higher-order fixed-filter ICs like the LTC1562 series. The device serves as a modular component for constructing custom analog front-end filters rather than a standalone complete filter solution.

Replacement Considerations

LT1568 offers similar functionality with a higher cutoff frequency capability up to 10MHz.
