REF43GPZ

Overview

The REF43GPZ is a low-power precision voltage reference IC from Analog Devices, providing a stable +2.5V output. It operates within an input voltage range of 4.5V to 40V and draws a supply current of 450µA. The device features a fixed output accuracy of ±0.1% and can source up to 20 mA. It is designed for operation across a temperature range of -40°C to 85°C (TA). The component is housed in an 8-DIP package with a width of 0.300 inches (7.62 mm) and supports through-hole mounting.

Feature Summary

• Provides a stable +2.5V output independent of supply voltage, load conditions, or ambient temperature variations
• Low-power design with minimal supply current consumption
• High precision with fixed output accuracy of ±0.1%
• Wide input voltage range supporting diverse power supply architectures

Applications

• Precision analog-to-digital converter (ADC) references
• Data acquisition systems requiring stable voltage sources
• Instrumentation circuits needing low-drift references
• Battery-powered devices where power efficiency is critical

Procurement Notes

Verify the specific suffix 'GPZ' confirms lead-free and RoHS compliance status as per manufacturer documentation. Ensure the 8-DIP package dimensions match your PCB footprint requirements. Confirm the operating temperature range meets your environmental specifications. Cross-reference the part number with official Analog Devices distributors to ensure authenticity and availability.

Selection Notes

Select this component when a fixed 2.5V reference is required with high accuracy and low power consumption. The wide input voltage range allows flexibility in system design. Consider the through-hole package if prototyping or specific mechanical constraints necessitate DIP packaging over surface-mount alternatives. Verify that the 20 mA output current capability suffices for the intended load.

Part Context

The REF43 series consists of low-power precision voltage references offering stable outputs. The REF43GPZ specifically denotes the 2.5V variant in an 8-pin DIP package. This series is engineered to maintain performance despite variations in supply voltage, load, and temperature, making it suitable for applications demanding reliable reference voltages.

Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible substitutes within the REF43 family or other precision reference series. Verify electrical parameters such as output voltage, accuracy, and current draw before substitution. Ensure thermal and package compatibility matches the original design requirements.
