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.
