LT3095EUDD#PBF

Overview

The LT3095EUDD#PBF is a dual-channel low noise bias generator from Analog Devices. It generates two independent power rails from a common input voltage ranging from 3V to 20V. Each channel integrates a fixed-frequency, peak current-mode switching regulator and a low-noise, single-resistor-programmable linear regulator with a 50mA output current capability. The device supports various topologies including SEPIC and Boost configurations to accommodate diverse input-to-output voltage requirements.

Feature Summary

• Dual-channel architecture providing independent low-noise bias supplies from a single input source
• Integrated switching regulators utilizing fixed-frequency peak current-mode control for efficient conversion
• Onboard linear regulators offering low-noise performance with single-resistor programmability

Applications

• Generating multiple low-noise bias voltages for sensitive analog circuits
• Powering RF front-ends requiring clean DC supply rails
• Providing auxiliary power in systems with varying input voltage ranges

Procurement Notes

Verify the specific suffix EUDD against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure the part number matches the exact ordering code required for your design. Cross-reference with authorized distributors to confirm current availability status as supply conditions may vary.

Selection Notes

Select this component when designing circuits that require isolated or independent low-noise power rails derived from a single unregulated or regulated input source. Consider the input voltage range of 3V to 20V and the need for both switching efficiency and linear regulation noise performance in your application.

Part Context

The LT3095 belongs to a family of dual-channel bias generators designed for applications demanding high power supply rejection and low noise. It combines switching and linear technologies to optimize performance across different load and line conditions within a compact footprint suitable for dense PCB layouts.

Replacement Considerations
