ADR3450

微功耗，高精度电压基准 Micropower, High Accuracy Voltage References

Product Details

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