Intersil debuts precision operational amplifiers

The products feature a combination of low noise and low power coupled with low offset voltage, low bias current drift and minimal offset drift over temperature.

The products are said to be ideal for applications that require reduced power consumption, high DC accuracy and AC performance needed to condition a range of precision analogue signals.

The single ISL28117 and dual ISL28217 are capable of reducing signal conditioning error.

This is achieved through a combination of lower noise, lower offset voltage, lower bias current and higher gain accuracy.

These amplifiers enable high gain processing of wide common-mode voltage signals with accuracy.

Applications include medical instruments, precision active filters, power supply control, programmable logic controllers and digital oscilloscopes.

The ISL28117 and ISL28217 feature a wide operating temperature range of -40C to +125C.

The combination of low noise and low power meet the requirements for signal gain front ends in industrial control applications, while reducing overall power consumption for high signal-count designs.

The wide supply voltage range of +/-2.25V to +/-20V enables more flexibility for wide common-mode range applications.

Full-trench isolation process technology prevents latch-up, while high ESD ratings of 4.5kV (human body model) and 500V (machine model) are designed to prevent in-field failures for industrial applications such as data acquisition and process control.
