1 / 13 page 1 ® FN6301.1 ISL28276, ISL28476 Dual and Quad Precision Micropower Single Supply Rail-to-Rail Input and Output Precision Op Amps The ISL28276 and ISL28476 are Dual and Quad channel micropower precision operational amplifier optimized for single supply operation at 5V and can operate down to 2.4V. For equivalent performance in a single channel op-amp reference EL8176. The ISL28276 and ISL28476 feature an Input Range Enhancement Circuit (IREC) which enables both parts to maintain CMRR performance for input voltages equal to the positive and negative supply rails. The input signal is capable of swinging 0.5V above a 5.0V supply (0.25V for a 2.4V supply) and to within 10mV from ground. The output operation is rail to rail. The both parts draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. Offset current, voltage and current noise, slew rate, and gain-bandwidth product are all two to ten times better than other micropower op-amps with equivalent supply current ratings. The ISL28276 and ISL28476 can be operated from one lithium cell or two Ni-Cd batteries. The input range includes both positive and negative rail. Features • 60µA supply current per channel • 100µV max offset voltage • 500pA input bias current • 400kHz gain-bandwidth product • 115dB PSRR and CMRR • Single supply operation down to 2.4V • Input is capable of swinging above V+ and within 10mV of Ground • Rail-to-rail output • Output sources 31mA load current • Pb-free plus anneal available (RoHS compliant) Applications • Battery- or solar-powered systems • 4mA to 25mA current loops • Handheld consumer products • Medical devices • Thermocouple amplifiers • Photodiode pre-amps • pH probe amplifiers Ordering Information PART NUMBER (Note) PART MARKING TAPE & REEL PACKAGE (Pb-Free) PKG.
