package. For high accuracy, output voltage and temperature 0.5/1.0 ADR130 coefficient are trimmed digitally during final assembly using 1.2 ADR3412 Analog Devices, Inc., patented DigiTrim® technology. ADR280 2.048 ADR360 REF191 ADR430 Stability and system reliability are further improved by the low ADR3420 ADR440 output voltage hysteresis of the device and low long-term output 2.5 ADR3425 ADR291 ADR431 ADR03 voltage drift. Furthermore, the low operating current of the AD1582 REF192 ADR441 AD780 device (100 μA maximum) facilitates usage in low power ADR361 devices, and its low output noise helps maintain signal integrity 3.0 ADR3430 REF193 ADR433 ADR06 in critical signal processing systems. AD1583 These CMOS are available in a wide range of output voltages, all ADR363 ADR443 AD780 of which are specified over the industrial temperature range of 3.3 ADR366 REF196 −40°C to +125°C. ADR3433
