ADR370:  PRECISION LOW POWER 2.048 V SOT-23 VOLTAGE REFERENCE

Product Description

The ADR370* is a low cost, 3-terminal (series) band gap voltage reference featuring high accuracy, high stability, and low power consumption packaged in a tiny 3-lead SOT-23 package. Precise matching and thermal tracking of on-chip components, as well as patented temperature drift curvature correction design techniques, have been employed to ensure that the ADR370 provides an accurate 2.048 V output.

This micropowered, low dropout voltage device sources or sinks up to 5 mA of load current while providing a stable 2.048 V output. The compact footprint, high accuracy, and operating range of 2.3 V to 15 V make the ADR370 ideal for use in 3 V and 5 V systems where there can be wide variations in supply voltage and a need to minimize power dissipation.

The ADR370 is offered in A and B grades; all devices are specified over the extended industrial range of −40°C to +125°C.

Applications

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

    • * Protected by U.S. Patent No. 5,969,657; other patents pending.
