ADR290 General Description

The ADR290, ADR291 and ADR292 are low noise, micropower precision voltage references that use an XFET® reference circuit. The new XFET architecture offers significant performance improvements over traditional bandgap and Buried Zener-based references. Improvements include: one quarter the voltage noise output of bandgap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis and excellent long-term stability.

The ADR29x family are series voltage references providing stable and accurate output voltages from supplies as low as 2.35 V for the ADR290. Output voltage options are 2.048 V, 2.5 V, and 4.096 V for the ADR290, ADR291, and ADR292 respectively. Quiescent current is only 12 A, making these devices ideal for batterypowered instrumentation. Three electrical grades are available offering initial output accuracies of ±2 mV, ±3 mV and ±6 mV max for the ADR290 and ADR291, and ± 3 mV, ±4 mV and ±6 mV max for the ADR292. Temperature coefficients for the three grades are 8 ppm/°C, 15 ppm/°C, and 25 ppm/°C max, respectively. Line regulation and load regulation are typically 30 ppm/V and 30 ppm/mA, maintaining the reference's overall high performance. For a device with 5.0 V output, refer to the ADR293 data sheet.

The ADR290, ADR291, and ADR292 references are specified over the extended industrial temperature range of 40°C to +125°C. Devices are available in the 8-lead SOIC and 8-lead TSSOP packages.
