Rail-to-Rail Op Amp Draws Just 150 µA

Operating on power supply voltages from 2.7V to 36V, the LT6011 dual rail-to-rail op amp consumes less than 150 µA of supply current. The device specifies an input offset voltage below 75 µV, input bias current less than 0.9 nA, and a low noise voltage density of 14 nV/Hz. Minimum open loop gain is 120 dB and CMRR is beyond 115 dB. Maintaining accuracy over temperature and time, the op amp has an input offset voltage drift of 0.8 µV/°C with a long-term stability of 0.4 µV per month. The device is available in eight-pin SOIC and DFN packages rated for operation over commercial and industrial temperature ranges. Pricing starts at $1.95 each/1,000.
