LT3095IUDD#PBF

Overview

The LT3095IUDD#PBF is a dual-channel low noise bias generator manufactured by Analog Devices Inc. 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 capable of delivering up to 50mA. The device supports various topologies including boost and SEPIC configurations to accommodate different input-output voltage requirements.

Feature Summary

• Dual-channel architecture providing simultaneous switching and linear regulation
• Single-resistor programmability for output voltage adjustment
• Integrated low-noise linear regulators for sensitive analog loads
• Flexible topology support for diverse input-to-output voltage ratios

Applications

• Generating low noise bias supplies for RF and microwave circuits
• Powering precision analog-to-digital converters requiring clean reference voltages
• Creating auxiliary power rails in mixed-signal systems
• Biasing operational amplifiers in instrumentation applications
