Intersil unveils 40V, low noise, precision instrumentation Amp with integrated ADC Driver

The ISL28617 incorporates a differential output to easily interface to today”s highest performance differential input ADCs. It offers excellent gain accuracy and gain temperature coefficient over a temperature range of -40°C to 125°C, with the industry”s highest common mode rejection ratio (CMRR) in all gain configurations. Noise measures only 8.6nV/Hz @ 1kHz and 85nVrms from 0.1Hz to 10Hz, and the ISL28617 can provide both high gain and attenuation, setting it apart from competing instrumentation amplifiers which typically are limited to gain only configurations. The ISL28617 is ideal for instrumentation, industrial, motor control and medical systems.

The ISL28617 is part of a precision, low noise signal chain solution from Intersil including the ISL21090 low noise voltage reference and the ISL26134 low noise 24-bit delta-sigma ADC.

Additionally, using Vishay Precision Group”s next generation Z-1 Bulk Metal Foil technology FRSM chip resistors provides gain setting with non-measurable noise while maintaining gain accuracy under extraordinary thermal and environmental stresses.
