Typical applicaTion
DescripTion
180MHz, 1mA Power
Efficient Rail-to-Rail
I/O Op Amps
TheLTC6246/LTC6247/LTC6248aresingle/dual/quadlow
power,highspeedunitygainstablerail-to-railinput/output
operational amplifiers. On only 1mA of supply current they
feature an impressive 180MHz gain-bandwidth product,
90V/s slew rate and a low 4.2nV/√Hz of input-referred
noise. The combination of high bandwidth, high slew rate,
low power consumption and low broadband noise makes
these amplifiers unique among rail-to-rail input/output op
amps with similar supply currents. They are ideal for lower
supply voltage high speed signal conditioning systems.
TheLTC6246familymaintainshighefficiencyperformance
from supply voltage levels of 2.5V to 5.25V and is fully
specified at supplies of 2.7V and 5.0V.
For applications that require power-down, the LTC6246
and the LTC6247 in MS10 offer a shutdown pin which
disables the amplifier and reduces current consumption
to 42A.
The LTC6246 family can be used as a plug-in replacement
for many commercially available op amps to reduce power
or to improve input/output range and performance.
