REF35360QDBVR

Overview

The REF35360QDBVR is a nanopower, high-precision shunt voltage reference from the Texas Instruments REF35 family. It provides a fixed 3.6V output with ±0.05% initial accuracy and a maximum temperature coefficient of 12ppm/°C over the -40°C to +105°C range. The device operates on a typical quiescent current of 650nA and supports an input voltage up to 6V. It features a 6-pin SOT-23 package, low-frequency noise of 3.3ppmP-P (0.1Hz to 10Hz), and includes dedicated EN and NR pins for power management and noise reduction.

Feature Summary

• Ultra-low power consumption with 650nA typical quiescent current
• High precision with ±0.05% initial accuracy and 12ppm/°C max temperature coefficient
• Low-noise performance with 3.3ppmP-P output noise in the 0.1Hz to 10Hz band
• Integrated enable pin for shutdown mode and noise reduction pin for filtering

Applications

• Flow transmitters
• Blood glucose monitors
• Servo drive control modules
• Power quality analyzers
• Process analytics systems

Procurement Notes

Verify the specific ordering suffix 'QDBVR' against the manufacturer's latest orderable addendum to confirm availability and exact specifications. Ensure the application environment remains within the recommended operating conditions, specifically the input voltage limits and thermal ranges defined in the datasheet. Confirm that the required output capacitance falls within the stable range of 0.1µF to 10µF for proper operation.

Selection Notes

Select this component when a fixed 3.6V reference is required with minimal power draw. The SOT-23-6 package is suitable for space-constrained designs. Consider the 12ppm/°C drift specification for applications requiring stability across industrial temperatures. The presence of an enable pin allows for system-level power savings, while the noise reduction pin offers flexibility for sensitive analog front ends.

Part Context

This part belongs to the REF35 series of ultra-low-power, high-precision voltage references. The series offers various fixed output voltages ranging from 1.024V to 5.0V. The REF35360QDBVR specifically denotes the 3.6V variant housed in a 6-pin SOT-23 package. Other variants in the family include different voltage outputs and package options like WCSP.

Replacement Considerations

Direct substitutes within the same family include other REF35xxQDBVR parts with different fixed output voltages if the voltage level can be adjusted or if a different reference value is acceptable. Verify pin compatibility and electrical specifications before substitution.
