Product Details

The ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/ADR3440/ADR3450 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.

These CMOS are available in a wide range of output voltages, allof which are specified over the industrial temperature range of −40°C to +125 °C.
