ISL28270, ISL28273, ISL28470 Dual and Quad Channel Micropower, Single Supply, Rail-to-Rail Input and Output (RRIO) Instrumentation Amplifiers The ISL28270 and ISL28273 are dual channel micropower instrumentation amplifiers (in-amps) and the ISL28470 is a quad channel in-amp optimized for single supply operation over the +2.4V to +5.5V range. All three devices feature an Input Range Enhancement Circuit (IREC) which maintains CMRR performance for input voltages equal to the positive supply and down to 50mV above the negative supply rail. The input signal is capable of swinging above the positive supply rail and to 10mV above the negative supply with only a slight degradation of the CMRR performance. The output operation is rail-to-rail. The ISL28273 is compensated for a minimum gain of 10 or more. For higher gain applications, the ISL28270 and ISL28470 are compensated for a minimum gain of 100. The in-amps have bipolar input devices for best offset and excellent 1/f noise performance. The amplifiers can be operated from one lithium cell or two Ni-Cd batteries. Features • 150µV max offset voltage (ISL28270, ISL28470) • 600µV max offset voltage (ISL28273) • 2.5nA max input bias current (ISL28270, ISL28470) • 110dB CMRR • 0.7µV/°C offset voltage temperature coefficient • 240kHz -3dB bandwidth (G = 100) ISL28270, ISL28470 • 230kHz -3dB bandwidth (G = 10) ISL28273 • Single supply operation • Rail-to-rail input and output (RRIO) • Pb-free plus anneal available (RoHS compliant) Applications • Battery or solar-powered systems • Strain gauge • Sensor signal conditioning • Medical devices • Industrial instrumentations Related Literature • AN1289, ISL28470EVAL1Z Evaluation Board User’s Guide • AN1290, ISL2827xINEVAL1Z Evaluation Board User’s Guide • AN1298, Instrumentation Amplifier Application Note Ordering Information PART NUMBER (Note) PART MARKING PACKAGE (Pb-Free) PKG.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. Data Sheet August 3, 2007 |
