Frequently Asked Questions
What is the output voltage accuracy of the REF5030IDG4?
The REF5030IDG4 provides a precision 3.0 V reference with an initial accuracy of ±0.1%, meaning the output voltage is guaranteed within ±3 mV of the nominal 3.000 V. This tight tolerance makes it suitable for driving high-resolution ADCs and DACs without external trimming.
What are the typical operating temperature range and temperature coefficient for the REF5030IDG4?
The REF5030IDG4 operates over the industrial temperature range of −40 °C to +125 °C. Its typical temperature coefficient is 3 ppm/°C, which means the output voltage drift across the full temperature range is very low, making it well suited for precision measurement systems that must perform reliably in harsh environments.
How much output current can the REF5030IDG4 supply, and what package does it use?
The REF5030IDG4 can source up to 10 mA of output current, which is sufficient to drive multiple downstream loads simultaneously without significant voltage droop. The device is housed in an 8-pin SOIC (Small Outline IC) package, offering a compact footprint that is easy to hand-solder or place with standard SMT assembly equipment.
What is the output noise performance of the REF5030IDG4 and why does it matter?
The REF5030IDG4 exhibits a low-frequency noise of only 3 µVpp (0.1 Hz to 10 Hz), which is critical for high-resolution data acquisition systems. Low reference noise directly limits the effective number of bits (ENOB) achievable by an ADC; with 3 µVpp noise on a 3 V reference, system designers can target 16-bit or higher resolution without noise from the reference becoming the bottleneck.
In what applications is the REF5030IDG4 most commonly used?
The REF5030IDG4 is commonly used in precision analog applications such as high-resolution data converters (ADC/DAC references), instrumentation amplifiers, medical measurement equipment, industrial process control, and portable battery-powered instruments. Its combination of low noise, low temperature drift, and 10 mA drive capability makes it a versatile choice wherever a stable 3.0 V reference is required.
