LT1790ACS6-2.5#TRMPBF

Voltage Reference Overview

The LT1790ACS6-2.5#TRMPBF is a micropower low dropout series voltage reference providing a nominal output of 2.5V in a 6-lead ThinSOT package. It features A-grade accuracy with a maximum initial error of 0.05% and a temperature coefficient of 10ppm/°C. The device operates within a supply range of 3V to 18V, drawing a maximum supply current of 60µA. It supports both sourcing and sinking currents, ensuring stable performance across specified load conditions.

Voltage Reference Feature Summary

• Curvature compensation and post-package trimming ensure high output accuracy and low temperature drift.
• Capable of sourcing and sinking current for flexible positive or negative reference configurations.
• Minimized thermally induced hysteresis maintains stability during temperature excursions.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the #TRMPBF suffix indicates tape and reel packaging with specific unit counts per reel as defined by Analog Devices. Confirm the 'A' grade designation matches the required 0.05% initial accuracy and 10ppm/°C temperature coefficient specifications. Ensure the commercial temperature range (0°C to 70°C) aligns with system requirements.

Voltage Reference Selection Notes

Select this component when high precision is required in a compact form factor. The A-grade specification provides tighter tolerance than B-grade options. Consider the low dropout voltage and micropower consumption for battery-sensitive designs. Verify that the 60µA supply current meets power budget constraints compared to shunt references.
