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 DigiTrim® 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, all of which are specified over the industrial temperature range of −40°C to +125 °C.
