Isl28117 and isl28217 introduced by INTERSIL (NASDAQ Global Select market code: ISIL), a global leader in high performance analog semiconductor design and manufacturing, add two new members to its fast-growing bipolar Low-Power Precision Operational Amplifier Series.

The two products ideally combine low noise and low power consumption, as well as low bias voltage, low bias current drift and minimum zero drift over the operating temperature range. These products are very suitable for a variety of precision analog signal conditioning applications, which need to reduce power consumption, high DC precision and AC performance.

Compared with the existing competitive schemes, isl28117 and dual channel isl28217 reduce the signal conditioning error by using lower noise, lower bias voltage, lower bias current and higher gain accuracy. These amplifiers achieve high gain processing of wide common mode voltage signal, and the accuracy is much better than the competitive scheme.

These two devices have a wide range of applications, including medical instruments, precision active power filter, power control, programmable logic controller and digital oscilloscope.
