Intersil Unveils New Series of Bipolar Low-Power Operational Amplifiers

Intersil, a company that designs and manufactures high-performance analog and mixed-signal semiconductors, reportedly announced two new bipolar low-power precision operational amplifier series.

 

The new ISL28117 and ISL28217 are an “ideal combination of low noise and low power coupled with low offset voltage, low bias current drift and minimal offset drift over temperature,” company officials said.

 

With these features, the amplifiers meet the requirements for signal gain front ends in industrial control applications, while reducing overall power consumption for high signal-count design, company sources said.

 

The new amplifiers are suitable for applications that require reduced power consumption, high DC accuracy and AC performance needed to condition a wide range of precision analog signals, they claimed.

 

Medical instruments, precision active filters, power supply control, programmable logic controllers and digital oscilloscopes are examples of some applications where ISL28117 and ISL28217 find the best use.

 

The single ISL28117 and dual ISL28217 are capable of reducing signal conditioning error in a competitive manner. This is achieved through a combination of lower noise, lower offset voltage, lower bias current and higher gain accuracy.

 

Intersil’s new amplifiers enable high gain processing of wide common-mode voltage signals with better accuracy than competing solutions, company officials claimed.

The ISL28117 and ISL28217 feature a wide operating temperature range of -40 to 125 degrees Celsius and a wide supply voltage range of +/-2.25V to +/-20V enabling more flexibility for wide common-mode range applications.

 

Featuring full-trench isolation process technology, ISL28117 and ISL28217 prevent latch-up. With high ESD ratings of 4.5kV (human body model) and 500V (machine model), they prevent in-field failures for industrial applications such as data acquisition and process control, company sources said.

 

Intersil recently announced a pair of low voltage, high-current, low dropout (LDO) linear regulators, TMCnet reported. The ISL80102 and ISL80103 are specified for 2A and 3A output current, respectively.

 

Built on the new BiCMOS technology, these new LDOs provide the industry's fastest transient response, meaning the output voltage is properly regulated under varying load current changes, company officials said.
