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., patented 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.
