The pact 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. Rev.
