LT1567CMS8#PBF

Overview

The LT1567CMS8#PBF is a precision analog building block from Analog Devices, housed in an 8-lead MSOP package. 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 a gain-bandwidth product of up to 190MHz. Key electrical parameters include a typical input offset voltage of 0.5mV, a noise density of 1.4nV/√Hz, and a maximum operating temperature of +85°C.

Feature Summary

• Integrates two low-noise op amps with one dedicated unity-gain inverter for optimized high-frequency linearity
• Provides differential outputs with equal gain and 180-degree phase shift for single-ended to differential conversion
• Supports second-order multiple feedback filter configurations with cutoff frequencies up to 5MHz

Applications

• Antialiasing or reconstruction filtering in high-speed data communications systems
• Communication channel or roofing filters
• Video signal processing
• Direct driving of high-speed differential input A/D converters

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and standard tube packaging. Confirm the 'C' grade designation meets the required commercial temperature range specifications. Ensure the source documentation matches the exact part number to avoid confusion with other variants in the LT1567 family.

Selection Notes

Select this component when designing active filters requiring megahertz bandwidths with minimal external components. The integrated inverter simplifies circuit topology for differential applications. Verify that the power supply voltage falls within the 2.7V to 12V range and that the load requirements do not exceed the output drive capabilities specified in the datasheet.

Part Context

This component belongs to the LT1567 series of continuous-time filter building blocks. It is designed to replace discrete amplifier solutions by providing matched characteristics and internal biasing. The MSOP-8 package allows for compact surface-mount implementation in space-constrained designs.

Replacement Considerations

LT1568IMS8#PBF: Offers similar low-noise performance but provides a fourth-order filter structure instead of two amplifiers.
