1.6V High Precision Op Amps Consume Less then 1uA

(PresseBox) ( MILPITAS, )
Linear Technology Corporation announces a new family of ultralow power op amps that set a new standard for precision low voltage operation and tiny footprint. The LT6003 (single), LT6004 (dual) and LT6005 (quad) amplifiers draw less than 1uA and operate from 1.6V to 16V. With input offset voltage of 500uV max at 25°C and a maximum drift of 5uV/°C, the LT6003 family is the most precise low voltage ultra low op amp. A tiny 2mm x 2mm DFN package makes the footprint of the LT6003 the smallest in this class and inputs and outputs feature rail-to-rail operation. The LT6003 family is ideal for battery-operated, handheld instrumentation due to the combination of low supply current, 1.6 to 16V operating range and tiny packages. For many micropower amplifiers, rail-to-rail operation compromises the supply current, with up to a threefold current increase as the output approaches the rails. According to Linear Technology Design Manager, Mike Kultgen, "The LT6003 family uses unique design techniques to preserve its micropower operation in all normal operating conditions as well as during startup, when the amplifier output is likely to be at the supply rail." Both leaded and leadless DFN packages are available with fully guaranteed specs over commercial (0oC to 70oC), industrial (-40oC to 85oC) and automotive (-40oC to 125oC) temperature ranges. The LT6003 family is available now with 1000-piece prices of $0.72, $1.10 and $1.75 for the single LT6003, dual LT6004, and quad LT6005, respectively.
