Product details

1. Product overview
The ADR440BRZ-REEL7 is a voltage reference chip based on ADI's patented XFET technology in a SOIC-8 package designed for high-precision electronic systems. Its core function is to provide a stable reference voltage for analog-to-digital converters (ADC), digital-to-analog converters (DAC) and sensors to ensure the long-term reliability and low error of the system signal chain.

2. Core specifications
Output voltage: 4.096V (fixed)

Initial accuracy: ±0.04% (Max)

Temperature coefficient: 3ppm/°C (typical, 0°C to 70°C)

Noise performance: 4μVpp (0.1Hz to 10Hz band)

Load adjustment rate: ±0.005%/mA

Operating temperature range: -40°C to +125°C

Supply current: 800μA (typical)

Package type: SOIC-8

3. Performance advantage
Ultra-low noise: A noise level of 4μVpp significantly improves the dynamic range of a high-resolution ADC.

Long-term stability: XFET technology ensures long-term drift characteristics of 50ppm/√kHr, suitable for long-term operation of equipment.

Wide temperature adaptability: High accuracy at extreme temperatures, suitable for industrial and vehicle-mounted environments.

Low power design: 800μA static current optimizes the energy efficiency of battery-powered devices.

4. Typical application scenarios
Industrial automation: Provides reference voltage for 24-bit ADC in PLC module to improve sensor signal acquisition accuracy.

Medical equipment: High stability signal chain for portable blood glucose meter and blood pressure monitor.

Test and measurement: Support oscilloscope, multimeter calibration reference source requirements.

Automotive electronics: Meet the high temperature environmental stability requirements of the on-board battery management system (BMS).

5. Design suggestions
PCB layout optimization: Shorten the line distance between the reference source and the ADC, reduce noise coupling.

Power decoupling: It is recommended to configure a 10μF tantalum capacitor and 0.1μF ceramic capacitor near the VIN pin.

Temperature management: Increase heat dissipation design in high temperature applications to avoid drift caused by self-heating of the chip.
