FN6154.5
39µA Micropower Single and Dual
Precision Rail-to-Rail Input-Output (RRIO)
Low Input Bias Current Op Amps
Features
• 39µA typical supply current
• 5nA max input bias current
The ISL28156 and ISL28256 are micropower precision
operational amplifiers optimized for single supply operation
at 5V and can operated down to 2.4V.
• 250kHz gain bandwidth product (A = 1)
V
• 2.4V to 5.5V 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 0.5V above a 5.0V supply
(0.25V for a 2.5V supply) and to within 10mV from ground.
The output operation is rail-to-rail.
• Enable pin (ISL28156 only)
• Pb-free (RoHS compliant)
Applications
• Battery- or solar-powered systems
• 4mA to 20mA current loops
• Handheld consumer products
• Medical devices
The 1/f corner of the voltage noise spectrum is at 1kHz. This
results in low frequency noise performance, which can only
be found on devices with an order of magnitude higher than
the supply current.
ISL28156 and ISL28256 can be operated from one lithium
cell or two Ni-Cd batteries. The input range includes both
positive and negative rail. The output swings to both rails.
• Sensor amplifiers
• ADC buffers
• DAC output amplifiers

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.

Input Protection
Applications Information
All input terminals have internal ESD protection diodes to both
positive and negative supply rails, limiting the input voltage to
within one diode beyond the supply rails. They also contain
back-to-back diodes across the input terminals. For
applications where the input differential voltage is expected to
exceed 0.5V, external series resistors must be used to ensure
the input currents never exceed 5mA (Figure 35).
Introduction
The ISL28156 is a single BiMOS rail-to-rail input, output
(RRIO) operational amplifier with an enable feature. The
ISL28256 is a dual version without the enable feature. Both
devices are designed to operate from single supply (2.4V to
5.0V) or dual supplies (±1.2V to ±2.5V) while drawing only
39µA of supply current per amplifier. This combination of low
power and precision performance makes this device suitable
for a variety of low power applications including battery
powered systems.

Rail-to-Rail Input/Output
These devices feature bi-polar inputs, which have an input
common mode range that extends up to 0.5V beyond the V+
rail, and to within 10mV of the V- rail. The CMOS outputs
typically swing to within about 4mV of the supply rails with a
100kΩ load. The NMOS sinks current to swing the output in
the negative direction. The PMOS sources current to swing the
output in the positive direction.
FIGURE 35. INPUT CURRENT LIMITING
Enable/Disable Feature
The ISL28156 offers an EN pin that disables the device when
pulled up to at least 2.0V. In the disabled state (output in a
high impedance state), the part consumes typically 10µA. By
disabling the part, multiple ISL28156 parts can be connected
together as a MUX. In this configuration, the outputs are tied
together in parallel and a channel can be selected by the EN

It is possible to exceed the +125°C maximum junction

to determine if power supply voltages, load conditions, or
package type need to be modified to remain in the safe
operating area. These parameters are related using
Equation 1:
Using Only One Channel
The ISL28256 is a dual op amp. If the application only
requires one channel, the user must configure the unused
channel to prevent it from oscillating. The unused channel
will oscillate if the input and output pins are floating. This will
result in higher than expected supply currents and possible
noise injection into the channel being used. The proper way
to prevent this oscillation is to short the output to the
negative input and ground the positive input (as shown in
Figure 36).
