Frequently Asked Questions
What is the output voltage and accuracy of the REF5020AIDGKT?
The REF5020AIDGKT provides a precision 2.048V output voltage with an initial accuracy of ±0.1% (typ). Its very low temperature coefficient of 3ppm/°C (typical) ensures the output remains stable across the full industrial temperature range of -40°C to +125°C.
What is the input voltage range for the REF5020AIDGKT?
The REF5020AIDGKT operates with an input voltage from 2.7V minimum up to 18V maximum, making it compatible with a wide variety of single-supply and dual-supply system designs including 3.3V, 5V, 12V, and 15V power rails.
What applications is the REF5020AIDGKT best suited for?
The REF5020AIDGKT is ideal for precision data acquisition systems, industrial process control, medical instrumentation, and portable test equipment. Its 2.048V output matches the full-scale range of many 12-bit ADCs and DACs, and its ultra-low noise of 3.2μVp-p makes it suitable for high-resolution measurement applications.
What package does the REF5020AIDGKT come in and what are its dimensions?
The REF5020AIDGKT is packaged in an 8-pin MSOP (VSSOP) small outline package (JESD-30 code S-PDSO-G8), which is compact and suitable for space-constrained PCB designs. It is RoHS compliant (Pb-free) and is rated for industrial temperature range operation.
Is there a pin-compatible alternative to the REF5020AIDGKT?
Texas Instruments offers the REF5020 family in multiple grades and packages. The REF5020AID (SOIC-8) and REF5020AIDBZT (SOT-23-5) are alternatives with similar specifications. Third-party alternatives include the ADR3420 from Analog Devices, which also provides a 2.048V output with comparable drift performance.
