LT1567CMS8#TRPBF

Overview

The LT1567CMS8#TRPBF 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 from 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 above 100dB. The component is housed in an 8-lead MSOP surface mount package.

Feature Summary

• Integrates two wideband rail-to-rail op amps with one dedicated unity-gain inverter
• Enables single-ended to differential conversion for direct ADC driving
• Optimized for megahertz frequency second-order filter sections

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance. Confirm the 'C' grade designation meets the required operating temperature range specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing active filters requiring cutoff frequencies up to 5MHz with minimal added noise. Ensure the design accommodates the shared DC bias node between the uncommitted amplifier and the internal inverter. Verify that the source impedance remains low relative to the filter input resistors to maintain accurate frequency response characteristics.

Part Context

This part belongs to the LT1567 series of analog building blocks designed specifically for high-frequency signal conditioning. It serves as a foundational element for constructing complex continuous-time filters without requiring external clock signals, distinguishing it from switched-capacitor alternatives.

Replacement Considerations

LT1568: Offers similar functionality but includes four amplifiers and supports cutoff frequencies up to 10MHz.
