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  
• 1mA typical supply current (per amplifier)  
• 650µV maximum offset voltage  
• 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.
