What are the key features of ADR3450ARJZ?
- High initial accuracy of ±0.1% typical ensures precise reference voltage of 5.0 V for ADC and DAC calibration without trimming
- Micropower supply current in the microamp range extends battery life in portable measurement and data-acquisition systems
- Low temperature coefficient minimizes output voltage drift across temperature, maintaining measurement accuracy from -40°C to +125°C
- Compact 6-pin SOT-23 package simplifies layout in space-constrained precision analog front-end designs
What is ADR3450ARJZ used for?
ADR3450ARJZ is used as a precision 5.0 V reference in data-acquisition systems, portable test equipment, and industrial sensor interfaces where high initial accuracy and low drift are required. Its micropower consumption makes it ideal for battery-operated handheld instruments, 4-20 mA loop-powered transmitters, and remote sensing nodes that must maintain reference accuracy across a -40°C to +125°C temperature range. The 6-pin SOT-23 footprint fits easily into compact analog front-end circuits alongside precision ADCs and DACs.

Frequently Asked Questions
What output voltage does ADR3450ARJZ provide, and what accuracy can designers expect?
ADR3450ARJZ provides a fixed 5.0 V reference output with high initial accuracy of approximately ±0.1% typical. This level of precision eliminates the need for external trimming in most precision measurement applications and directly drives the reference input of 12-bit and 14-bit ADCs without degrading conversion accuracy.
How does the low supply current of ADR3450ARJZ benefit battery-powered instruments?
ADR3450ARJZ draws micropower supply current in the microamp range, which is negligible compared to the load current of a data-acquisition circuit. In a battery-powered instrument with a 1000 mAh cell, the reference contributes almost no quiescent drain, allowing the system to remain operational for thousands of hours in standby or low-duty-cycle modes.
Over what temperature range does ADR3450ARJZ maintain its accuracy, and what is the package?
ADR3450ARJZ is specified over a -40°C to +125°C industrial temperature range with a low temperature coefficient, ensuring its 5.0 V output remains stable across automotive and industrial operating conditions. It is housed in a 6-pin SOT-23 package, one of the smallest through-hole-compatible leaded packages, keeping the PCB footprint under 3 mm x 2 mm.
When should a designer choose ADR3450ARJZ over a less accurate voltage reference?
ADR3450ARJZ is the right choice when system accuracy requirements demand a reference error below ±0.1% across the full -40°C to +125°C range, for example in 12-bit or higher resolution ADC/DAC circuits, precision weigh scales, or industrial 4-20 mA transmitters. A lower-accuracy 1% or 2% reference would introduce systematic errors of tens of millivolts at a 5.0 V reference level, which is unacceptable for high-resolution conversion.
