40V precision operational amplifiers

The new 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 designed for applications that require reduced power consumption, dc accuracy and ac performance needed to condition a wide range of precision analogue signals. The single ISL28117 and dual ISL28217 are said to be capable of reducing signal conditioning error 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 and applications include medical instruments, precision active filters, power supply control, programmable logic controllers and digital oscilloscopes. The devices feature an operating temperature range of -40 to 125^°C. 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 supply voltage range of +/- 2.25 to +/-20V enables 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. The ISL28117 single amplifiers are available in 8-lead SOIC. The ISL28217 dual amplifiers are available now in 8-lead SOIC packages.
