Typical Applications
REF5030AIDGKR is suitable for 6 applications: Precision Data Acquisition Systems, Industrial Process Control, Medical Instrumentation, Portable Battery-Powered Devices, Automotive Electronics, Test and Measurement Equipment.
Precision Data Acquisition Systems
The REF5030AIDGKR provides a stable 3V reference for high-resolution ADCs and DACs in data acquisition systems. Its low noise (3 µVpp/V) and low drift (3 ppm/°C) ensure accurate conversions over temperature. The 10 mA output current can drive multiple converter reference inputs. The wide input range (up to 18V) allows operation from various supply rails, simplifying power design. In a typical system, the reference is placed close to the ADC's VREF pin with a 0.1 µF decoupling capacitor to minimize noise coupling.
Recommended
Industrial Process Control
In industrial process control, the REF5030AIDGKR ensures accurate analog signal conditioning for sensors and actuators. Its very low drift (3 ppm/°C) maintains accuracy over the -40°C to +125°C temperature range, critical for harsh environments. The device can source or sink current, making it suitable for bipolar signal conditioning circuits. The small VSSOP-8 package fits compact PLC modules and field transmitters. The wide input range allows direct connection to 24V industrial supplies with proper headroom.
Recommended
Medical Instrumentation
The REF5030AIDGKR is ideal for medical devices such as patient monitors and diagnostic equipment, where precision and reliability are paramount. Its low noise and low drift ensure accurate measurements in ECG, EEG, and blood pressure monitoring. The device operates over the full medical temperature range and is RoHS compliant. The 10 mA output current can power multiple analog front-end stages. The small package enables miniaturized wearable devices.
Recommended
Portable Battery-Powered Devices
For battery-powered devices, the REF5030AIDGKR's low supply current (0.8 mA typical) helps extend battery life. The wide input range (3.2V to 18V) allows operation from a variety of battery chemistries, including 2-cell Li-ion (up to 8.4V) and 12V lead-acid. The low dropout voltage (200 mV) ensures regulation even when the battery is nearly discharged. The device's small footprint is ideal for handheld instruments and IoT sensors.
Recommended
Automotive Electronics
The REF5030AIDGKR is AEC-Q100 qualified, making it suitable for automotive applications such as battery management systems, engine control units, and infotainment. Its low drift (3 ppm/°C) ensures accurate voltage monitoring over the automotive temperature range. The wide input range (up to 18V) handles automotive supply transients. The device's low noise improves the performance of automotive ADCs used in sensor interfaces.
Recommended
Test and Measurement Equipment
In test and measurement equipment, the REF5030AIDGKR provides a stable reference for calibrators, multimeters, and signal generators. Its high accuracy (±0.1%) and low noise (3 µVpp/V) are essential for precise measurements. The device can source or sink current, allowing it to be used in both positive and negative reference circuits. The wide input range and small package make it easy to integrate into benchtop instruments.

Key Differentiators
- Very low temperature drift of 3 ppm/°C (vs REF3030AIDBZR)
- Low output noise of 3 µVpp/V (vs REF3030AIDBZR)
- Wide input voltage range up to 18V (vs REF3030AIDBZR)
Design Notes
Place a 0.1 µF ceramic capacitor close to the IN pin and a 1 µF to 10 µF capacitor on the OUT pin for stability. The output capacitor is required for proper operation; use a low-ESR ceramic capacitor. Keep traces short to minimize noise pickup.
The REF5030AIDGKR dissipates minimal power due to its low supply current (0.8 mA typical). However, at high input voltages (e.g., 18V) and maximum load (10 mA), power dissipation is about 150 mW. The VSSOP-8 package has a thermal resistance of approximately 150°C/W, so junction temperature rise is about 22.5°C, which is acceptable. Ensure adequate copper area for heat dissipation if operating at high ambient temperatures.
Do not exceed the maximum input voltage of 18V. Ensure the load current does not exceed 10 mA, as this can degrade accuracy. The output capacitor must be within the specified range (1 µF to 10 µF) to maintain stability. Avoid using high-ESR capacitors on the output.
