REF35160YBHR

Overview

The REF35160YBHR is a precision series voltage reference from Texas Instruments, delivering a fixed output of 1.6 V. It features ultra-low quiescent current of 650 nA and an initial accuracy of ±0.05%. The device exhibits a temperature coefficient of 12 ppm/°C and supports input voltages from 1.85 V to 6 V. It operates within a temperature range of -40°C to +125°C and is housed in a compact 4-pin DSBGA package.

Feature Summary

• Ultra-low power consumption with typical quiescent current of 650 nA
• High precision with maximum initial accuracy of ±0.05%
• Low drift characteristics with temperature coefficient of 12 ppm/°C

Applications

• Battery-powered instrumentation systems
• Portable medical devices requiring low power
• Data acquisition systems needing stable reference voltages

Procurement Notes

Verify the specific suffix YBHR corresponds to the 4-DSBGA package and reel/cut-tape packaging configuration. Confirm that the 1.6V output variant matches the system requirement, as the REF35 family offers multiple voltage options. Ensure compatibility with the specified operating temperature range of -40°C to +125°C for the intended application environment.

Selection Notes

Select this component when both ultra-low power consumption and high precision are critical constraints. The 1.6V output is suitable for single-supply applications where the reference voltage must be lower than the supply rail. Consider the small 4-DSBGA footprint if board space is limited, while ensuring the PCB layout supports the thermal requirements for operation up to +125°C.

Part Context

This part belongs to the REF35 family of nanowatt, low-drift, precision voltage references. The family provides various fixed output voltages ranging from 1.024V to 5.0V. The REF35160YBHR specifically utilizes the 4-pin DSBGA package, offering a space-saving solution compared to larger packages like SOT-23 or WCSP found in other variants of the same series.

Replacement Considerations

Other REF35 variants with different output voltages (e.g., REF35125, REF35250) share similar electrical characteristics but provide different reference levels. Direct substitution requires matching the required output voltage. Packages such as SOT-23-6 may require adapter solutions due to pinout differences.
