LT1790ACS6-3#TRMPBF

Voltage Reference Overview

The LT1790ACS6-3#TRMPBF is a micropower series voltage reference from Analog Devices, housed in a 6-lead TSOT-23 package. It provides a fixed output of 3V with an initial accuracy of ±0.05% and a maximum temperature coefficient of 10ppm/°C. The device operates within a commercial temperature range of 0°C to 70°C and supports input voltages up to 18V. It features low supply current of 60µA maximum, ensuring minimal power dissipation suitable for battery-operated systems.

Voltage Reference Feature Summary

• Curvature compensation and trimmed thin-film resistors ensure high precision and low drift.
• Capable of sourcing and sinking current for flexible positive or negative reference configurations.
• Post-package trimming minimizes thermal hysteresis and enhances output stability.

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 indicates tape and reel packaging with 500 units per reel as documented in official ordering information. Confirm the 'A' grade designation corresponds to the required 0.05% accuracy and 10ppm/°C drift specifications. Ensure the commercial temperature range (0°C to 70°C) meets system requirements, as industrial grades are available with different suffixes.

Voltage Reference Selection Notes

Select this component when high accuracy and low power consumption are critical in space-constrained designs. The TSOT-23 package offers a low profile suitable for portable applications. Consider the A-grade specifications for tight tolerance requirements. Verify that the input voltage remains within the specified dropout limits for both sourcing and sinking operations.

Voltage Reference Part Context

This part belongs to the LT1790 family of micropower SOT-23 low dropout references. The family combines high accuracy with small package size and low supply current. Variants include different output voltages and temperature grades, such as the industrial -40°C to 85°C range. The LT1790 is designed for applications requiring stable references with minimal power impact.
