34µA Micro-power Single and Dual
Precision Rail-to-Rail Input-Output (RRIO)
Low Input Bias Current Op Amps
The ISL28158 and ISL28258 are micro-power precision
operational amplifiers optimized for single supply operation
at 5.5V and can operate down to 2.4V.
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 the positive
supply and to 100mV below the negative supply with only a
slight degradation of the CMRR performance. The output
operation is rail-to-rail.
The ISL28158 and ISL28258 draw minimal supply current
while meeting excellent DC-accuracy noise and output drive
specifications. Competing devices seriously degrade these
parameters to achieve micro-power supply current. Offset
current, voltage and current noise, slew rate, and gain
bandwidth product are all two to ten times better than on
previous micro-power op amps.
The 1/f corner of the voltage noise spectrum is at 100Hz.
This results in low frequency noise performance, which can
only be found on devices with an order of magnitude higher
supply current.
ISL28158 and ISL28258 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.

... Applications Information Introduction The ISL28158 is a single CMOS rail-to-rail input, output (RRIO) operational amplifier with an enable feature. The ISL28258 is a dual version without the enable feature. Both devices are designed to operate from single supply (2.4V to www.datasheet4u.com 5.5V) or dual supplies (±1.2V to ±2.75V). ...

Page 13

... Using Only One Channel The ISL28258 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 ...
