LT1461DHS8-4#PBF

Voltage Reference Overview

The LT1461DHS8-4#PBF is a micropower precision low dropout series voltage reference from Analog Devices, housed in an 8-lead plastic SO package. It provides a fixed 4.096V output with an initial accuracy of ±0.15% and a maximum temperature coefficient of 20ppm/°C. The device operates over a –40°C to 125°C temperature range, drawing a maximum supply current of 70µA. It supports a minimum output drive of 50mA and features a shutdown capability.

Voltage Reference Feature Summary

• Advanced curvature compensation techniques ensure low temperature drift and high output accuracy.
• Integrated thermal shutdown protects the component from overload conditions.
• Shutdown pin allows for system power down and full load current switching.

Voltage Reference Applications

• A/D and D/A Converters
• Precision Regulators
• Handheld Instruments

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm the DH grade corresponds to the industrial temperature range of –40°C to 125°C. Ensure the ordering code matches the exact 4.096V output requirement. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Voltage Reference Selection Notes

Select this variant for applications requiring high accuracy over a wide industrial temperature range. The 4.096V output is suitable for standard ADC references. Consider the 70µA supply current for battery life calculations. Verify that the 50mA output drive meets the load requirements. Check PCB layout guidelines to minimize stress-induced voltage shifts.

Voltage Reference Part Context

This component belongs to the LT1461 family of micropower precision low dropout series voltage references. The DH designation identifies the specific accuracy and temperature coefficient grades within the product line. Other variants offer different output voltages and performance levels.
