Description
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.
