5MHz, Single and Dual Rail-to-Rail
Input-Output (RRIO) Op Amps
The ISL28146 and ISL28246 are low-power single and dual
operational amplifiers optimized for single supply operation
from 2.4V to 5.5V, allowing operation from one lithium cell or
two Ni-Cd batteries. They feature a gain-bandwidth product
of 5MHz and are unity-gain stable with a -3dB bandwidth of
13MHz.
These devices feature an Input Range Enhancement Circuit
(IREC) which enables them to maintain CMRR performance for
input voltages greater than the positive supply. The input signal
is capable of swinging 0.25V above a 5.0V supply and to within
10mV from ground. The output operation is rail-to-rail.
The parts draw minimal supply current while meeting
excellent DC accuracy, AC performance, noise and output
drive specifications. The ISL28146 features an enable pin
that can be used to turn the device off and reduce the supply
current to only 16µA. Operation is guaranteed over -40°C to
+125°C temperature range.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
