DESCRIPTIO
The LT
high precision input performance with low power con-
sumption and rail-to-rail output swing.
Input offset voltage is trimmed to less than 60 V. The low
drift and excellent long-term stability guarantee a high
accuracy over temperature and time. The 300pA maxi-
mum 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 135 A 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 –40 C to 85 C. The LT6011 (dual) is available in
SO-8 and space saving 3mm 3mm DFN packages. The
LT6012 (quad) is available in SO-14 and 16-pin SSOP
packages.

... Capacitive Loads The LT6011/LT6012 can drive capacitive loads up to 500pF in unity gain. The capacitive load driving capability increases as the amplifier is used in higher gain configurations. A small series resistance between the output and the load further increases the amount of capacitance that the amplifier can drive ...
