Intersil Introduces Industry's First 40V Low Noise Precision Instrumentation Amplifier with Integrated ADC Driver

California, MILPITAS --- July 10, 2012 - Intersil, a global leader in high-performance analog mixed-signal semiconductor design and manufacturing, today announced the launch of a new 40V low-noise instrumentation amplifier, the industry's first integrated analog/digital Converter (ADC) level shifter and precision amplifier for the driver.

The ISL28617 includes a differential output that can be easily connected to current high performance differential input precision ADCs. It offers excellent gain accuracy and gain temperature coefficient (in the -40°C to 125°C temperature range), and the Common Mode Rejection Ratio (CMRR) is the industry's highest in all gain configurations. The ISL28617's noise density measurements are only 8.6nV/√Hz (1kHz) and 85nVrms (0.1Hz to 10Hz), while providing high gain and attenuation, making it stand out from competing instrumentation amplifiers (competitive amplifiers are usually limited to Gain configuration). The ISL28617 is ideal for instrumentation, industrial, motor control and medical systems.

Features and specifications

• Integrated differential output ADC driver simplifies the design of high performance 24-bit instrumentation systems

• Excellent solution for both single and dual supply voltage operation

• Unlike competitor amplifiers, it offers the high gain (10,000x) and attenuation (0.1x) required for flexible data acquisition systems

• Low noise characteristics make it ideal for noise sensitive high gain applications

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

In addition, the use of Vishay Precision Group's next-generation Z-1 large foil technology FRSM chip resistors provides gain settings for unmeasurable noise while maintaining excellent gain accuracy under extreme heat and ambient pressures.

Pricing and availability

The ISL28617 is available now in a compact 24-lead TSSOP package and is priced at $2.85 in 1,000-piece quantities. For more information please visit: http://
