Product Details
The ADR1000H-EBZ allows the evaluation of the ADR1000AHZ, ultra-stable 6.6V Shunt Voltage Reference in 8-Pin TO-99 package.
The DUT is centered in a fan shaped cutout of the PCB, designed to weaken mechanical coupling from the PCB to the DUT (effective for temperature and humidity, but not flexure). There are also thermal "baffles" (slots) in the PCB to keep heat from coupling from the heater transistor to the control circuit, and between the DUT and the resistors. The heater temperature is set by the standard 13k:1k divider as with the old LTZ1000. However, the ADR1000 runs about 5 degrees warmer (75C) than the LTZ1000 (70C), due to the slightly lower voltage of the ADR1000 applied to the divider.
