LT1790AIS6-2.048#TRPBF

Voltage Reference Overview

The LT1790AIS6-2.048#TRPBF is a micropower series voltage reference from Analog Devices, housed in a 6-lead TSOT-23 package. It provides a fixed output of 2.048V with an initial accuracy of ±0.05% and a temperature coefficient of 10ppm/°C. The device operates within a supply voltage range of 2.8V to 18V and draws a maximum supply current of 60µA. It functions reliably across an industrial temperature range of –40°C to 85°C.

Voltage Reference Feature Summary

• Curvature compensation and post-package trimming ensure high precision and low drift
• Capable of sourcing and sinking current for positive or negative reference applications
• Low dropout voltage design minimizes power dissipation in battery-operated systems

Voltage Reference Applications

• Handheld Instruments
• Negative Voltage References
• Industrial Control Systems
• Data Acquisition Systems
• Battery-Operated Equipment

Voltage Reference Procurement Notes

Verify the specific suffix #TRMPBF against the datasheet ordering information to confirm tape and reel packaging availability. Ensure the component matches the specified industrial temperature grade and lead-free finish requirements for your assembly process.

Voltage Reference Selection Notes

Select this part when high accuracy and low power consumption are critical. The A-grade specification guarantees tighter tolerance than B-grade options. Consider the low dropout characteristic for efficient operation near minimum supply voltages in portable designs.

Voltage Reference Part Context

This component belongs to the LT1790 family of micropower SOT-23 low dropout references. The family combines high accuracy with small package size, utilizing thin-film resistors for trimmed precision. It serves as a compact alternative to shunt references by eliminating the need to idle entire load currents.
