Intersil Achieves 1nV Noise Performance in a Single-Supply Op Amp

MILPITAS, CA, July 02, 2007 ¨C Intersil Corporation (NASDAQ Global Select: ISIL) today announced the release of the ISL28190, ISL28290, ISL28191 and ISL28291. These devices, part of Intersil¡¯s pinPOINT™ Precision Analog product line, deliver noise performance up to four times better than competitive single-supply op amps. The ISL28X90 sets the new industry standard for single-supply, rail-to-rail output op amps at 1.0nV/rt(Hz), while the ISL28X91 comes in at just 1.7nV/rt(Hz).

As the industry¡¯s first ultra-low noise, single-supply op amps, these devices allow designers to simplify designs by achieving noise performance previously only attained with dual supply devices. This, along with the industry¡¯s best harmonic distortion (THD+N) at 0.00017% (ISL28X90) and 0.00018% (ISL28X91) make this family of rail-to-rail output op amps ideally suited for noise-sensitive audio, medical and industrial instrumentation applications.

These op amps are optimized for operation at 5V and below, with the single channel amplifiers offered in a space-saving SOT23 package while the dual channel amplifiers are offered in a 10-lead MSOP package. Single channel amps in 1.6mm x 1.6mm micro-TDFN package and dual channel amps in the 1.8mm x 1.4mm micro-TDFN package are now sampling.

The combination of superior noise, harmonic distortion and bandwidth performance is in keeping with Intersil¡¯s complete pinPOINT™ Precision Analog product line¡¯s commitment to unwavering accuracy over time and temperature.
