OBSOLETE PRODUCT — ADR390:  2.048 V Micropower, Low Noise Precision Voltage References with Shutdown

The ADR390 is a precision 2.048 V band gap voltage reference featuring low power and high precision in a tiny footprint. Using patented temperature drift curvature correction techniques from Analog Devices, Inc., the ADR390 reference achieves a low 9 ppm/°C of temperature drift in the TSOT package.

The ADR39x family of micropower, low dropout voltage references provides a stable output voltage from a minimum supply of 300 mV above the output. Their advanced design eliminates the need for external capacitors, which further reduces board space and system cost. The combination of low power operation, small size, and ease of use makes the ADR39x precision voltage references ideally suited for battery-operated applications.

Applications

  • Battery-powered instrumentation
  • Portable medical instrumentation
  • Data acquisition systems
  • Industrial process controls
  • Automotive
