Intersil ISL28478
The ISL28278 and ISL28478 are Dual and Quad channel micropower precision operational amplifier optimized for single supply operation at 5V and can operate down to 2.4V. For equivalent performance in a single channel op-amp reference EL8178. The ISL28278 and ISL28478 feature an Input Range Enhancement Circuit (IREC) which enables both parts to maintain CMRR performance for input voltages equal to the positive and negative supply rails.| Part No. | ISL28478 |
