GENERAL DESCRIPTION
The ADR34xx series of devices are low-cost, low-power, high
precision voltage references, featuring ± 0.1% initial accuracy,
low operating current and low output noise in a small SOT23
package.
For high accuracy, output voltage and temperature coefficient
are trimmed digitally during final assembly using Analog
Devices’ proprietary Digi-Trim technology. Stability and
reliability are further improved by the devices’ low output
voltage hysteresis and low long-term output voltage drift.
www.DaFtuarSthheeremt4oUr.ce,otmhe low operating current of the device (70 μA
max) facilitates usage in low-power devices, while its low output
noise helps maintain signal integrity in critical signal processing
systems.
ADR34xx series references are available in a wide range of
output voltages, all of which are specified over the industrial
temperature range of -40°C to +125 °C.

THEORY OF OPERATION
TBD
LONG-TERM STABILITY
One of the key parameters of the ADR34xx series of references
is long-term stability. Regardless of output voltage, internal
testing during development showed a typical drift of
approximately 50 ppm after 1,000 hours of continuous, non-
loaded operation in a +25°C environment.
It is important to understand that long-term stability is not
guaranteed by design, and that the output from the device may
shift beyond the typical 50 ppm specification at any time,
especially during the first 200 hours of operation. For systems
that require highly stable output over long periods of time, the
designer should consider burning-in the devices prior to use to
minimize the amount of output drift exhibited by the reference
over time. Refer to application note AN-713 for more
information regarding the effects of long-term drift and how it
can be minimized.
POWER DISSIPATION
The ADR34xx series voltage references are capable of sourcing
up to 10 mA of load current at room temperature across the
rated input voltage range. However, when used in applications
subject to high ambient temperatures, the input voltage and
load current should be carefully monitored to ensure that the
device does not exceeded its maximum power dissipation
rating. The maximum power dissipation of the device can be
calculated via the following equation:
[W]
where,
www.DaPtDaS=hedeet4vUic.ecopmower dissipation
Tj = device junction temperature
TA = ambient temperature
θJA = package (junction-to-air) thermal resistance
Due to this relationship, acceptable load current in high-
temperature conditions may be less than the maximum current-
sourcing capability of the device. In no case should the part be
operated outside of its maximum power rating as doing so may
result in premature failure or permanent damage to the device.
