Overview
The REF196GRUZ-REEL7 is a precision micropower voltage reference from the Analog Devices REF19x series, providing a fixed nominal output of 3.3 V. It operates within an input supply range of 3.5 V to 15 V and delivers up to 30 mA of load current while consuming a maximum of 45 μA in active mode. The device features a low dropout voltage and includes a sleep mode that reduces supply current to less than 15 μA. It is housed in an 8-lead TSSOP package and specified over an industrial temperature range of −40°C to +85°C.
Feature Summary
- Utilizes patented temperature drift curvature correction circuitry for high accuracy
- Includes short-circuit protection and low dropout voltage capability
- Features a dedicated sleep pin for power reduction
Applications
- Portable instruments
- ADCs and DACs
- Smart sensors
- Solar powered applications
- Loop-current-powered instruments
Procurement Notes
Verify the specific electrical grade (G Grade) and tolerance specifications against the official datasheet before procurement. Confirm that the 8-TSSOP package matches the design requirements. Ensure the REEL7 suffix aligns with the required tape and reel packaging format for automated assembly processes.
Selection Notes
Select this component when a stable 3.3 V reference is needed with minimal quiescent current consumption. The G Grade offers ±0.3% initial accuracy suitable for precision measurement systems. Consider the 30 mA output current capability if driving moderate loads directly without external buffering.
Part Context
This part belongs to the REF19x series of precision band gap voltage references manufactured by Analog Devices Inc. The series utilizes laser trimming of thin-film resistors to achieve low temperature coefficients. The REF196 variant specifically provides a 3.3 V output, distinguishing it from other members like the REF192 (2.5 V) or REF195 (5.0 V).
Replacement Considerations
Consult the official ordering guide for direct equivalents within the REF19x family. Verify compatibility regarding package type and electrical grades when substituting.
