GENERAL DESCRIPTION
The ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/ ADR3440/ADR3450 are low cost, low power, high precision
CMOS voltage references, featuring ±0.1% initial accuracy, low operating current, and low output noise in a small SOT-23 package. For high accuracy, output
voltage and temperature coefficient are trimmed digitally during final assembly using Analog Devices, Inc., proprietary DigiTrim® technology.
Stability and system reliability are further improved by the low output
voltage hysteresis of the device and low long-term output
voltage drift. Furthermore, the low operating current of the device (100 μA maximum) facilitates usage in low power devices, and its low output noise helps maintain signal integrity in critical signal processing systems.
These
CMOS 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.
