5,0 V reference sets new benchmarks

13 August 2003 Power Electronics / Power Management

The X60008CIS8-50 and X60008DIS8-50 from Xicor are claimed to have a performance that eclipses many of the most accurate voltage references currently available with guaranteed absolute initial accuracy as low as ±0,5 mV, straight-line temperature coefficients as tight as 5 ppm/°C and long term stability of 10 ppm/1000 Hrs while consuming a mere 500 nA of supply current. Existing voltage references that achieve initial accuracies tighter than ±1 mV with temperature stability less than 5 ppm/°C are expensive as well as limited in availability. The company says that its propriety FGA technology easily achieves performance levels that exceed the best of conventional buried-zener and band-gap technologies by storing the reference voltage as a precisely controlled charge on a floating gate device. The devices have 10 ppm/1000 hrs long term stability, 30 µVp-p (0,1 to 10 Hz) noise voltage and operate from -40 to +85°C.
