The ADR434 from Analog Devices Inc. is a member of the XFET® voltage reference family, which features ultralow noise, high accuracy, and low temperature drift performance. This voltage reference is an ideal choice for precision data conversion systems and high-resolution analog-to-digital converters (ADCs), providing a stable reference under a wide range of operating conditions.

Key Features

• Low Noise: The ADR434 boasts an impressive low noise specification of only 1.0 μV p-p (0.1 Hz to 10 Hz), making it one of the quietest voltage references in its class. This characteristic ensures minimal signal interference and enhances the signal integrity in sensitive applications.
• High Accuracy: With an initial accuracy of ±0.1%, the ADR434 provides precise voltage reference for critical applications where accuracy is paramount.
• Temperature Stability: The device features excellent temperature stability, with a maximum of 3 ppm/°C over the full industrial temperature range (-40°C to +125°C). This means the output voltage remains consistent despite changes in temperature.
• Wide Supply Range: The ADR434 operates with a supply range from 5 V to 18 V, accommodating a variety of power supplies and systems.
• Output Voltage Options: Available in several output voltage options, the ADR434 can provide a fixed output of 4.096 V, making it compatible with many ADCs and digital-to-analog converters (DACs).
• Trimming Capability: An external trim pin allows fine-tuning of the output voltage to compensate for voltage drops in series resistors or to adjust the voltage for specific needs.

Applications

The ADR434 is particularly suited for high-performance applications such as precision data acquisition systems, medical instruments, battery-powered devices, and industrial automation. Its low noise and high stability make it an excellent choice for reference in high-resolution conversion and measurement systems.
