GENERAL DESCRIPTION

The ADR1000 is a 6.62 V, output highly stable, oven-controlled,

buried Zener reference component built on an Analog Devices, Inc.,

proprietary bipolar process and is a pin-compatible replacement for

the LTZ1000. Included on the chip is a buried Zener reference,

a heater resistor for temperature stabilization, and a temperature

sensing transistor. External circuitry is used to set the operating currents

and the temperature of the reference, allowing the maximum

flexibility to achieve maximum long-term stability and minimum noise.

The ADR1000 application circuit can achieve a temperature coefficient

of <0.2 ppm/°C and a long-term drift of 0.5 ppm per year

(typical) after the first 3000 hours when properly implemented with

the recommended external circuitry shown in Figure 9 and with the

recommended layout.

The low long-term drift of the ADR1000 is well suited for any application

that must maintain accuracy over long calibration intervals

or product lifetime. The low thermal drift ensures the output is

constant with temperature variation because the on?chip heater of

the ADR1000 maintains a constant temperature higher than the

expected ambient range.

The ADR1000 is specified for operation over the extended industrial

temperature range of ?40°C to +125°C. To obtain the optimal

thermal drift performance, the temperature set point of the heater

needs to be 10°C higher than the maximum ambient temperature to

provide optimum stability of the buried Zener reference.

The ADR1000 comes packaged in an industry-standard, 8-pin

TO-99 metal can package that is hermetically sealed to resist the

effects of humidity.
