Linear Technology Introduces New Low Power Amplifiers

Linear Technology LT6003 LT6004 LT6005

The LT6003/LT6004/LT6005 from Linear Technology are single/dual/quad op amps designed to maximize battery life and performance for portable applications. These amplifiers operate on supplies as low as 1.6 V and are fully specified and guaranteed over temperature on 1.8 V, 5 V and ±8V supplies while only drawing 1 µA maximum quiescent current.

The ultralow supply current and low operating voltage are combined with excellent amplifier specifications; input offset voltage of 500 µV maximum with a typical drift of only 2 µV/°C, input bias current of 90pA maximum, open loop gain of 100,000 and the ability to drive 500pF capacitive loads, making the LT6003/LT6004/LT6005 amplifiers ideal when excellent performance is required in battery powered applications.

The single LT6003 is available in the 5-pin TSOT-23 and tiny 2 mm × 2 mm DFN packages. The dual LT6004 is available in the 8-pin MSOP and 3 mm × 3 mm DFN packages. The quad LT6005 is available in the 16-pin TSSOP and 5 mm × 3 mm DFN packages. These devices are specified over the commercial, industrial and automotive temperature ranges.
