Rail-to-Rail Output Precision
DESCRIPTIO
The LT
sion input performance with low power consumption and
rail-to-rail output swing.
Input offset voltage is trimmed to less than 35 V. 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 A of supply current on a 5V
supply. A power saving shutdown feature reduces supply
current to 12 A. 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.
