REF3318AIDCKT

Overview

The REF3318AIDCKT is a fixed series voltage reference manufactured by Texas Instruments, delivering a precise output of 1.8 V. It features an initial accuracy of ±0.15% and a temperature coefficient of 30 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 5 mA. It consumes a typical supply current of 3.9 µA, ensuring low power consumption. The component functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a compact SC-70-3 surface-mount package, suitable for space-constrained designs.

Feature Summary

Provides a stable 1.8 V reference with high initial accuracy of ±0.15%.
Features low quiescent current consumption of 3.9 µA for energy efficiency.
Operates over an extended industrial temperature range of -40°C to +125°C.

Applications

Precision analog-to-digital converter (ADC) reference sources
Digital-to-analog converter (DAC) voltage references
Battery-powered instrumentation systems

Procurement Notes

Verify the specific suffix 'CKT' corresponds to the SC-70-3 tape-and-reel packaging configuration. Confirm that the required operating temperature range aligns with the specified -40°C to +125°C limits. Ensure input voltage constraints do not exceed the 5.5 V maximum rating during system operation.

Selection Notes

Select this component when a 1.8 V output is required with tight initial accuracy. Consider the 30 ppm/°C drift characteristic for thermal stability requirements. Evaluate the SC-70-3 package dimensions against available board space. Compare the 3.9 µA current draw against system power budgets.

Part Context

This part belongs to the REF33xx family of precision voltage references from Texas Instruments. The family includes variants with different fixed output voltages such as 1.25 V, 2.048 V, 2.5 V, 3.0 V, and 3.3 V. All members share similar performance characteristics including low noise and high accuracy.
