AD584 High Precision 4-Channel Voltage Reference Module The AD584 Programmable Voltage Reference Module is a compact, high-accuracy calibration tool designed for engineers, technic ians, and electronics enthusiasts. Delivering four stable output voltages — 2.5V, 5V, 7.5V, and 10V — this module is the ideal reference source for calibrating multimeters, testing DAC/ADC converters, and verifying precision instruments. Made in Mainland China. Key Features Four Selectable Output Voltages: Easily program your desired reference voltage (2.5V, 5V, 7.5V, or 10V) by short-circuiting the corresponding terminal block — no complex setup required. Stable, Low-Noise Output: The onboard 15V battery provides a low-noise power source, ensuring rock-steady voltage output for dependable, repeatable results every time. Parallel Terminal Design: Two programming terminals are connected in parallel to minimise the influence of short-circuit resistance on the output voltage, improving overall output accuracy. Ultra-Low Power Consumption: With a quiescent current of just 1 mA (maximum), this module is highly efficient and well-suited for battery-powered measurement setups. Wide Input Voltage Range: Operates from 4.5V to 30V DC input (external power must exceed 11V DC for proper operation). 2mm Copper Test Sockets: The reference voltage output interface features 2mm copper test sockets, making it quick and easy to connect a pen-type multimeter for calibration. Factory Tested: Every board is individually tested using an Agilent 6-digit multimeter before shipment, with the measured output voltage clearly marked for user convenience. Improved Reliability: Substituted switch terminals offer enhanced reliability, greater flexibility, and support for smaller short-circuit resistors — optimising module performance. Specifications Model AD584 Voltage Reference Module Board Output Voltages 2.500V / 5.000V / 7.500V / 10.000V Operating Voltage 4.5V – 30V DC External Power Required >11V DC Quiescent Current 1 mA (maximum) Load Capacity 10 mA Dimensions 56 × 56 × 15 mm (2.2 × 2.2 × 0.59 in) Condition Brand New Country of Origin Made in Mainland China What's in the Box 1 × AD584 Voltage Reference Module Board Usage Tips For best accuracy, allow the module to warm up at room temperature (25°C / 77°F) for at least 30 minutes before taking measurements or performing calibration. This ensures thermal stability and maximum output precision. The AD584 chip is recommended as an external reference for 12-bit and 14-bit DAC/ADC converters, frequently outperforming standard standalone references in precision applications.

Frequently Asked Questions Q: What output voltages does the AD584 Voltage Reference Module support? A: The AD584 module supports four programmable output voltages: 2.500V, 5.000V, 7.500V, and 10.000V. You select your desired voltage by short-circuiting the corresponding programming terminal block on the board. Q: What input voltage does this module require to operate correctly? A: The module operates over a wide input range of 4.5V to 30V DC. However, the external power supply must provide more than 11V DC to ensure all four reference output voltages function correctly. Always make sure your working input voltage exceeds the programmed output voltage. Q: How do I calibrate my multimeter using this voltage reference module? A: Connect your DC power supply (above 11V) to the module's external power interface, select your desired reference voltage by programming the appropriate terminal, then plug your multimeter's test leads into the 2mm copper test sockets. Allow a 30-minute warm-up period at 25°C before taking readings for highest accuracy. The marked output voltage on each board (tested at the factory with an Agilent 6-digit multimeter) serves as your precise calibration reference. Q: Is this module suitable for use with DAC and ADC converters? A: Yes. The AD584 is specifically recommended as an external precision reference for 12-bit and 14-bit digital-to-analog (DAC) and analog-to-digital (ADC) converters. Its stable, low-noise output often surpasses the performance of standard standalone reference components in demanding precision applications. Q: What variants of the AD584 chip are available? A: The AD584 is available in three grades — AD584J, AD584K, and AD584L — each offering different levels of temperature coefficient performance and initial accuracy to suit a variety of precision measurement requirements. {"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "What output voltages does the AD584 Voltage Reference Module support?", "acceptedAnswer": {"@type": "Answer", "text": "The AD584 module supports four programmable output voltages: 2.500V, 5.000V, 7.500V, and 10.000V.
