Voltage Reference Choices from Analog Devices The ADR3412/ADR3420/ADR3425/ADR3430/ADR3433/ ADR3440/ADR3450 are low cost, low power, high precision VOUT Low Cost/ Ultralow Low High Voltage, (V) Low Power Power Noise High Performance CMOS voltage references, featuring 0.1% initial accuracy, low 0.5/1.0 ADR130 operating current, and low output noise in a small SOT-23 1.2 ADR3412 package. For high accuracy, output voltage and temperature ADR280 coefficient are trimmed digitally during final assembly using 2.048 ADR360 REF191 ADR430 Analog Devices, Inc., proprietary DigiTrim technology. ADR3420 ADR440 Stability and system reliability are further improved by the low 2.5 ADR3425 ADR291 ADR431 ADR03 output voltage hysteresis of the device and low long-term output AD1582 REF192 ADR441 AD780 voltage drift. Furthermore, the low operating current of the ADR361 device (100 A maximum) facilitates usage in low power 3.0 ADR3430 REF193 ADR433 ADR06 devices, and its low output noise helps maintain signal integrity AD1583 in critical signal processing systems. ADR363 ADR443 AD780 These CMOS are available in a wide range of output voltages, all 3.3 ADR366 REF196 of which are specified over the industrial temperature range of ADR3433 40C to +125C. 4.096 ADR3440 ADR292 ADR434 Table 1.
