ADR3412ARJZ

参考电压 Micro-Power High-Acc 1.2V

Micropower, High Accuracy  Voltage References

GENERAL DESCRIPTION ADR3412ARJZ

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.
