What are the key features of ADR3430ARJZ?
- High initial accuracy of ±0.1% and low temperature coefficient of 10 ppm/°C ensure stable 3.0 V reference output across the -40°C to +125°C industrial temperature range
- Micropower supply current typically under 100 µA enables use in battery-operated instruments and IoT sensor nodes where quiescent current directly impacts battery life
- 6-pin SOT-23 package (SOT-23-6) provides a compact footprint with output and enable pins, allowing controlled power sequencing and easy integration in tight PCB layouts
What is ADR3430ARJZ used for?
ADR3430ARJZ provides the precision reference voltage required by 12-bit and 16-bit ADCs and DACs in handheld test instruments and portable data acquisition systems, where its high accuracy and low temperature drift directly determine measurement system performance. Battery-powered medical monitors and industrial sensors rely on its micropower consumption — typically under 100 µA — to extend operating time between charges while maintaining a 3.0 V stable reference across the full temperature range. It is also used in smart transmitters and loop-powered 4-20 mA signal conditioners where every microamp of quiescent current must be justified by functional contribution.

Frequently Asked Questions
What accuracy and temperature coefficient does ADR3430ARJZ provide, and how does this affect ADC measurement error?
ADR3430ARJZ offers an initial output accuracy of ±0.1% and a temperature coefficient of 10 ppm/°C, meaning over a 100°C temperature range the reference voltage drifts by only 1 mV from its 3.0 V nominal value. For a 16-bit ADC with a 3.0 V full-scale range, this temperature-induced error represents less than 0.5 LSB of deviation, preserving measurement resolution across the industrial operating range of -40°C to +125°C.
How low is the quiescent current of ADR3430ARJZ and why does it matter for battery-powered designs?
ADR3430ARJZ operates with a quiescent supply current typically below 100 µA across its full supply range starting from 3.1 V. In a device powered by a 1000 mAh coin cell or AA battery, this draw equates to over 10,000 hours of reference supply time at idle, making it practical to keep the reference continuously powered in always-on sensor nodes without measurably shortening battery service life.
In a precision 16-bit DAC circuit, when would a designer choose ADR3430ARJZ over a higher-current bandgap reference?
ADR3430ARJZ is the preferred choice when the DAC requires a 3.0 V reference and the system power budget limits reference consumption to under 1 mA. Because the device provides 10 ppm/°C drift and ±0.1% accuracy without the higher quiescent current of higher-drive references, it is sufficient for 16-bit DACs requiring less than 1 mA of reference drive current, covering the majority of signal generation and calibration applications in portable test equipment.
What minimum input voltage does ADR3430ARJZ need to maintain its regulated 3.0 V output?
ADR3430ARJZ requires a minimum input supply of approximately 3.1 V to maintain its regulated 3.0 V output, providing a dropout headroom of about 100 mV. This tight headroom is especially useful in single-cell Li-ion powered systems, where the battery voltage can drop from 4.2 V at full charge to near 3.3 V at end of life, keeping the reference well within its operating input range and maintaining output accuracy throughout the battery discharge cycle.
