Bipolar op amp consumes 30% less

ISL28127 offers best-in-class performance for instrumentation, industrial and data acquisition

The ISL28127 is a 40V low-noise bipolar precision operational amplifier that operates with 20 percent lower noise and consumes 30 percent less power than competing devices. The device offers outstanding low-frequency voltage noise performance of 3.0volts/sqrtHz @ 10Hz, and excellent DC precision with 70 microV max offset voltage and 10nA max input bias current. It also features superb offset voltage drift performance of 0.5 microV/degree C max, and is unity-gain stable over the full -40 to +125 degree C temperature range. The ISL28127 exhibits a wide operating supply voltage range of 4.5V to 40V and a gain bandwidth of 10MHz.

These specifications make the ISL28127 ideal for laboratory instrumentation, automated test equipment, power line monitors, weight measurement systems, and environmental analyzers that require low DC noise. The low distortion and gain accuracy also make the ISL28127 ideal for low-noise preamps, loop filters, strain gauge sensors and precision power sources.

Key advantages of ISL28127 include:

• Ultra-low noise performance to achieve low noise gain error and high gain
accuracy for 12-bit to 24-bit signal front end applications.

• High DC precision for 12-bit to 24-bit processing over the extended
temperature range (low offset drift).

• Simplified design-in, due to the versatile wide voltage operating range that
provides extended dynamic range and full-scale input and output.

• High ESD protection (4kV HBM) reduces in-field failures for industrial
applications such as data acquisition and process control.
