Single Precision Rail-to-Rail Input-Output (RRIO) Low Input Bias Current Op Amps Eval Boards


The ISL28148EVAL1Z and ISL28158EVAL1Z evaluation boards are design platforms containing all the circuitry needed to characterize critical performance parameters of the ISL28148 and ISL28158 operational amplifiers, using a variety of user defined test circuits.

The ISL28148 high-speed operational amplifier features low power consumption, while the ISL28158 operational amplifier features ultra-low power consumption. All op amps have rail-to-rail output drive capability and are designed to operate with a single lithium cell or two Ni_Cd batteries.
