Intersil's Precision Instrumentation Amplifier Family includes single-channel, dual-channel and quad-channel products, with part numbers EL8170, ISL28270, ISL28470, respectively. These products feature high precision, low power consumption and ultra-high PSRR.
The ISL28470 quad RRIO instrumentation amplifier offers high precision with less than 150 µV input offset voltage, 84 µA/Amp input bias current, and 3.5 µVpp input noise, all packaged in a compact 28‑lead QSOP. It operates from a supply voltage range of 2‑4 V up to 5 V and provides excellent PSRR across temperature.
In addition to the ISL28470, the document lists the full Intersil precision analog family, including single, dual, and quad versions of both PNP and PMOS input stages, as well as low‑power precision op‑amps such as the ISL28278. Detailed electrical specifications and package information are provided for each part number.
