Intersil’s 40V Quad Precision Amplifiers Feature Lowest Noise, Low Power Consumption

19 MARCH 2012

Intersil Corporation expanded its family of precision amplifiers, introducing a set of 40V low power, high ESD products that provide excellent DC accuracy and noise performance. These new quad amplifiers are ideally suited for 12-bit to 24-bit process control, instrumentation and data acquisition applications.
Designed on Intersil’s PR40 advanced bipolar process, the ISL28407, ISL28417, and ISL28408 all meet the low noise requirements for high gain front ends in industrial control designs while reducing total power consumption for high signal count applications. The ISL28407 operates from 4.5V to 40V with an ultra-low bias current drift of 0.3pA/°C over temperature (-40°C to +85°C), which is 30 percent lower than competitive quad precision amps. The ISL28407’s low offset of 90uV maximum and offset drift of 0.8uV/°C maximum provide high DC accuracy over temperature. It features an industry-leading combination of low power (290uA maximum per channel), 1MHz bandwidth, low input bias current drift (0.3pA/°C) and low noise (13nV/ÖHz @ 1kHz).
The ISL28417 is designed for sensor front ends, DAC buffering, precision voltage regulation or low noise instrumentation applications that need a diverse range of signals.
