LT6011/LT6012
Dual/Quad 135µA, 14nV/âHz,
Rail-to-Rail Output
Precision Op Amp
Description
The LT®6011/LT6012 op amps combine low noise and high
precision input performance with low power consumption
and rail-to-rail output swing.
Input offset voltage is trimmed to less than 60µV. The low
drift and excellent long-term stability guarantee a high ac-
curacy over temperature and time. The 300pA maximum
input bias current and 120dB minimum voltage gain further
maintain this precision over operating conditions.
The LT6011/LT6012 work on any power supply voltage
from 2.7V to 36V and draw only 135µA of supply current
on a 5V supply. The output swings to within 40mV of
either supply rail, making the amplifier a good choice for
low voltage single supply applications.
The LT6011/LT6012 are specified at 5V and ±15V supplies
and from â40°C to 85°C. The LT6011 (dual) is available
in SO-8, MS8 and space saving 3mm à 3mm DFN pack-
ages. The LT6012 (quad) is available in SO-14 and 16-pin
SSOP packages.
