REF198GRUZ-REEL7

Overview

The REF198GRUZ-REEL7 is a precision micropower voltage reference from the Analog Devices REF19x series, housed in an 8-lead TSSOP package. It provides a nominal output voltage of 4.096 V with a maximum initial accuracy of ±2 mV and a temperature coefficient of 5 ppm/°C. The device operates within a supply voltage range of 3.5 V to 15 V, consuming a maximum supply current of 45 μA. It features low dropout voltage characteristics, short-circuit protection, and a sleep mode that reduces current consumption to less than 15 μA.

Feature Summary

• Utilizes patented temperature drift curvature correction circuitry and laser trimming for high stability.
• Includes a dedicated sleep pin to disable the output and minimize power consumption.
• Provides integrated short-circuit protection for enhanced reliability.
• Features low dropout voltage operation allowing stable performance near supply limits.

Applications

• Portable instruments
• ADCs and DACs
• Smart sensors
• Solar powered applications

Procurement Notes

Verify the specific electrical grade (E, F, or G) required for your application, as specifications vary by grade. Confirm the package suffix RU corresponds to the 8-lead TSSOP form factor. Ensure the REEL7 designation matches your automated assembly requirements. Cross-reference the datasheet revision L for the most current thermal and electrical limits before finalizing procurement.

Selection Notes

Select this component when a 4.096 V reference is needed with micropower constraints. Consider the REF19x series if low dropout voltage and short-circuit protection are critical design factors. Evaluate the available electrical grades against your accuracy and temperature coefficient requirements. Verify that the 8-lead TSSOP package fits your board layout constraints.

Part Context

This part belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices Inc. The series includes various fixed output voltages ranging from 2.048 V to 5.0 V. The REF198 specifically targets applications requiring a 4.096 V reference standard. All parts in this family share common architectural features like laser trimming and curvature correction circuits.

Replacement Considerations

Direct replacements include other members of the REF19x series such as REF191, REF192, REF193, REF194, REF195, and REF196, provided the output voltage difference is acceptable for the circuit design. Ensure any substitute maintains the same 8-lead TSSOP package and electrical grade specifications.
