LTC2063 from Analog Devices draws just 1.3μA (typ, 2μA max) from a 1.8V supply and achieves 5μV maximum input offset at 25°C, with maximum drift of 0.06μV/°C from -40°C to 125°C and 4.8μVp-p 0-10Hz integrated noise. Industrial uses are expected, in wireless sensor nodes and mesh networks. Maximum input bias current is 15pA at 25°C ...

This story continues at 5μV offset op amp consumes only 1.3μA
