Rail-to-Rail Output Precision

Op Amp with Shutdown

, LTC and LT are registered trademarks of Linear Technology Corporation.

The LT

sion input performance with low power consumption and

rail-to-rail output swing.

Input offset voltage is trimmed to less than 35

µV. The low

drift and excellent long-term stability guarantee a high

accuracy over temperature and over time. The 110pA

maximum input bias current and 120dB minimum voltage

gain further maintain this precision over operating

conditions.

The LT6010 works on any power supply voltage from 2.7V

to 36V, and draws only 135

µA of supply current on a 5V

supply. A power saving shutdown feature reduces supply

current to 12

µA. The output voltage swings to within

40mV of either supply rail, making the amplifier a good

choice for low voltage single supply operation.

The LT6010 is fully specified at 5V and

±15V supplies and

from –40

°C to 85°C. The device is available in SO-8 and

space-saving 3mm

× 3mm DFN packages. This op amp

is also available in dual (LT6011) and quad (LT6012)

packages.
