For high accuracy, output voltage and temperature coefficient

are trimmed digitally during final assembly using Analog

Devices, Incꢀ, patented DigiTrim® technologyꢀ Stability and

system reliability are further improved by the low output

voltage hysteresis of the device and low long-term output

voltage driftꢀ

Furthermore, the low operating current of the device (.00 μA

maximum) facilitates usage in low-power devices, while its low

output noise helps maintain signal integrity in critical signal

processing systemsꢀ
