ISL28191, ISL28291 Single and Dual Ultra-Low Noise, Rail-to-Rail, Op Amp The ISL28191 and ISL28291 are tiny single and dual ultra-low noise, ultra-low distortion operational amplifiers. Fully specified to operated down to +3V single supply. These amplifiers have outputs that swing rail-to-rail, and an input common mode voltage that extends to ground (ground sensing). The ISL28191 and ISL28291 are unity gain stable with an input referred voltage noise of 1.7nV/ √Hz. Both parts feature 2nd and 3rd harmonic distortion of -76dBc and -70dBc, respectively. The ISL28191 is available in the space-saving 6 Ld µTDFN (1.6mm x 1.6mm) and SOT-23 packages. The ISL28291 is available in the 10 Ld µTQFN (1.8mm x 1.4mm) and MSOP packages. All devices are guaranteed over -40°C to +125°C. Features • 1.7nV/ √Hz input voltage noise at 1kHz • Harmonic Distortion -76dBc, -70dBc, fo = 1MHz • 61MHz -3dB bandwidth • 630µV maximum offset voltage • 3µA input bias current • 100dB typical CMRR • 3V to 5.5V single supply voltage range • Rail-to-rail output • Ground Sensing • Enable pin • Pb-free plus anneal available (RoHS compliant) Applications • Low noise signal processing • Low noise microphones/preamplifiers • ADC buffers • DAC output amplifiers • Digital scales • Strain gauges/sensor amplifiers • Radio systems • Portable equipment • Infrared detectors Ordering Information PART NUMBER (Note) PART MARKING TAPE & REEL PACKAGE (Pb-free) PKG.
