Precision amplifiers keep the noise down
Single-supply op amps offer noise performance previously only attainable by using dual-supply devices.
Billed as the industry's first ultra-low-noise single-supply op amps, Intersil's ISL28190, ISL28290, ISL28191 and ISL28291 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

Intersil introduces stereo multiplexer
Intersil has developed the ISL54405, a CD/MP3 stereo 2:1 multiplexer designed to deliver ultra-low distortion audio source or load selector functions with very high signal muting.
The devices, part of Intersil's Pinpoint Precision Analogue product line, deliver noise performance up to four times better than competing 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, and the ISL28X91 comes in at just 1.7nV/(rt)Hz.
The op amps are optimised for operation at 5V and below, with the single- channel amplifiers offered in a space-saving SOT23 package and the dual- channel amplifiers are offered in a 10-lead MSOP package.
Single-channel amps in 1.6 x 1.6mm micro-TDFN packages and dual-channel amps in 1.8 x 1.4mm micro-TDFN packages are now sampling.
The combination of superior noise, harmonic distortion and bandwidth performance is in keeping with Intersil's complete Pinpoint Precision Analogue product line's commitment to unwavering accuracy over time and temperature.
The ISL28190 and the ISL28191 are available in quantities of 1000 in 6-lead SOT-23 packages, whereas the ISL28291 and the ISL28290 are available in quantities of 1000 in 10-lead MSOP packages.
