Low power op-amp provides 30 µV precision

The LT6023 dual low power operational amplifier features 30 µV maximum input offset voltage and 60 µs settling to 0.01%. The IC has a 1.4 V/μs slew rate and 20 μA max supply current; only 3 μA max in shutdown mode. 

The amplifiers input bias current is just 3 nA max and CMRR is 136 db, typical. Specified for a 3 to 30 V supply over –40° to 85°C and –40° to 125°C temperature ranges, the device is available in MSOP-8 and 3 x 3 mm DFN packages. From $1.85 ea/1,000.
