REF5025AQDRQ1 is an automotive‑qualified precision 2.5 V series voltage reference manufactured by Texas Instruments, delivering stable reference output with high initial accuracy, ultra‑low temperature drift and low wide‑band noise for high‑resolution analog‑to‑digital and digital‑to‑analog conversion circuits. Packaged in 8‑pin SOIC surface‑mount housing, this AEC‑Q100 certified device accepts 2.7 V‑18 V supply input, sources or sinks ±10 mA output current, and maintains reliable performance across the extended automotive temperature range of ‑40 °C to 125 °C, providing long‑term stable voltage benchmark for noise‑sensitive automotive and industrial measurement systems without extra compensation circuitry.
REF5025AQDRQ1 serves as the high‑precision voltage benchmark for automotive battery management systems, vehicle sensor signal acquisition modules, on‑board diagnostic hardware, industrial process control equipment, 16‑bit and higher resolution data‑acquisition boards, portable precision measuring instruments, optical detection systems and analog circuit calibration units, wherever consistent, noise‑free 2.5‑volt reference signal is required to guarantee measurement repeatability and conversion accuracy.
FAQ
Q: What is the core advantage of REF5025AQDRQ1 over non‑automotive voltage references?
A: It carries AEC‑Q100 qualification, wider high‑temperature endurance and enhanced reliability against automotive electrical transients.
Q: Is an output capacitor mandatory for operation?
A: A low‑ESR ceramic bypass capacitor near output pin is strongly recommended for stability and noise suppression.
