LTC6252/LTC6253/LTC6254
720MHz, 3.5mA Power
Efficient Rail-to-Rail
I/O Op Amps
DESCRIPTION
The LTC
®
6252/LTC6253/LTC6254 are single/dual/quad low
power, high speed unity gain stable rail-to-rail input/output
operational amplifiers. On only 3.5mA of supply current
they feature a 720MHz gain-bandwidth product, 280V/µs
slew rate and a low 2.75nV/√Hz of input-referred noise.
The combination of high bandwidth, high slew rate, low
power consumption and low broadband noise makes the
LTC6252 family 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.
The LTC6252 family maintains high efficiency performance
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 LTC6252 and
the LTC6253 in MS10 offer a shutdown pin which disables
the amplifier and reduces current consumption to 42µA.
The LTC6252 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.
