Intersil, a provider of analogue and mixed-signal semiconductors, has introduced the first in a family of operational amplifiers created using the company’s proprietary bipolar process technology.

The ISL28127 is a 40V low-noise bipolar precision operational amplifier that is claimed to operate with 20 per cent lower noise and consume 30 per cent less power than competing devices.

The device offers low-frequency voltage noise performance of 3.0nV/Hz at 10Hz and DC precision with a 70mV maximum offset voltage and a 10nA maximum input bias current.

It also features offset voltage drift performance of 0.5mV/C maximum and is unity-gain stable over the full -40C to +125C temperature range.

The ISL28127 exhibits an operating supply voltage range of 4.5V to 40V and a gain bandwidth of 10MHz.

These specifications make the ISL28127 suitable for laboratory instrumentation, automated test equipment, power line monitors, weight measurement systems and environmental analysers that require low DC noise.

The low distortion and gain accuracy also make the device suitable for low-noise preamps, loop filters, strain gauge sensors and precision power sources.

The ISL28127 offers: 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, thanks to the versatile voltage operating range that provides extended dynamic range and full-scale input and output; and high ESD protection (4kV HBM), which reduces in-field failures for industrial applications such as data acquisition and process control.

Pricing for the ISL28127 starts at USD1.05 (GBP0.63) each in 1,000-piece quantities in SOIC eight-lead packages.
