Tiny precision op amps draw less than 1?A

Linear Technology Corp. has announced a new family of ultralow-power op amps that's touted to set a new standard for precision low voltage operation and tiny footprint. The LT6003 (single), LT6004 (dual) and LT6005 (quad) amplifiers draw less than 1?A and operate from 1.6V to 16V. With input offset voltage of 500?V max at 25C and a maximum drift of 5?V/C, the LT6003 family is the most precise low voltage ultralow op amp, according to Linear Tech.

A 2-by-2mm DFN package makes the footprint of the LT6003 the smallest in this class and inputs and outputs feature rail-to-rail operation, said the company. The amp family is suitable for battery-operated, handheld instrumentation due to the combination of low supply current, 1.6-16V 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 Tech 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 (0 to 70C), industrial (-40C to 85C) and automotive (-40C to 125C) temperature ranges. The LT6003 family is available today with 1,000-piece pricing of 72 cents, $1.10 and $1.75 for the single LT6003, dual LT6004, and quad LT6005, respectively.
