REF196GP

Overview

The REF196GP is a precision micropower series voltage reference manufactured by Analog Devices Inc. It provides a fixed output of 3.3V with an initial accuracy of 0.06% and a temperature coefficient of 25 ppm/°C. The device operates within an input voltage range up to 18V and supports a maximum shunt current of 30 mA. It functions reliably across a temperature range of -40°C to +85°C. The component is housed in an SOIC-8 package, designed for surface mount installation, and belongs to the REF196 series of precision references.

• Includes short circuit protection for enhanced reliability

Applications

• Portable instrumentation systems
• A-to-D and D-to-A converter circuits
• Smart sensor interfaces
• Loop-powered instrumentation

Procurement Notes

Verify the specific suffix 'GP' against official Analog Devices documentation to confirm package type and availability status. Ensure compatibility with required operating temperatures and load conditions. Cross-reference part numbers carefully as suffixes often denote packaging or material variations that do not alter electrical function but affect physical integration.

Selection Notes

Select this component when a stable 3.3V reference with high accuracy is required in space-constrained designs. The SOIC-8 package offers a compact footprint compared to larger DIP options. Consider the 25 ppm/°C temperature coefficient for thermal stability requirements. Evaluate power consumption needs against the micropower characteristics for efficiency optimization in portable devices.

Part Context

The REF196 series represents Analog Devices' line of precision micropower voltage references. These components are engineered for applications demanding high stability and low noise. The REF196GP specifically utilizes the GP suffix to identify its package configuration within the broader family of REF19x devices, which share similar electrical performance profiles but differ in physical housing options.

Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify pinout compatibility and electrical specifications before substitution. Generic replacements may lack the specific accuracy or temperature coefficient of the original component.
