ADR3412:  Micro-Power, High-Accuracy 1.2V Voltage Reference

Product Details

Product Status:Recommended for New Designs

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.

Furthermore, the low operating current of the device (100 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.


  • Initial accuracy: ± 0.1%
  • Max. temp. coefficient: 10 ppm / °C
  • Operating temperature: -40°C – +125 °C
  • Output current: +10 mA source / -3 mA sink
  • Low quiescent current: 100 μA (max)
  • Low dropout voltage: 250 mV @ 2 mA
  • Output noise (0.1 – 10 Hz): <10 μV p-p at 1.2 V (typical)
  • SOT23-6 package
