FN6321.2
5MHz, Single and Dual Rail-to-Rail
Input-Output (RRIO) Op Amps
Features
• 5MHz gain bandwidth product @ A = 100
V
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.
• 13MHz -3db unity gain bandwidth
• 950µA typical supply current (per amplifier)
• 650µV maximum offset voltage (6 Ld SOT-23)
• 16nA typical input bias current
• Down to 2.4V single supply voltage range
• Rail-to-rail input and output
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.
• Enable pin (ISL28146 only)
• -40°C to +125°C operation
• Pb-free (RoHS compliant)
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.
Applications
• Low-end audio
• 4mA to 20mA current loops
• Medical devices
Ordering Information
• Sensor amplifiers
• ADC buffers

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.
