GENERAL DESCRIPTION

The circuit in Figure 2 illustrates the basic configuration for the

ADR225. Note the 10 μF/0.1 μF bypass network on the input

and at least 1 μF bypass capacitor on the output is required for

proper device operation. It is recommended that no

The ADR225 is a precision bandgap voltage reference specified

for very high temperature operation. It uses a micro-power

core topology and laser trimming of highly stable, thin-film

resistors to achieve a very low temperature coefficient and high

initial accuracy while consuming very little power. A maximum

operating current of 50 μA and a low dropout voltage allows the

device to function very well in battery-powered equipment.

connections be made to Pin 1, Pin 3, Pin 5, Pin 7, and Pin 8.

The reference is offered in an 8 lead SOIC plastic package with

an operating temperature range of −40°C to +175°C. It is also

available in an 8 lead ceramic flat pack (CFP) with an operating

temperature range of −40°C to +210°C. Both devices are

designed for robustness at extreme temperatures and are

qualified for 1000 hours of operation at the maximum

temperature rating.
