Amplifier

150µV max offset voltage

The ISL28270 and ISL28273 are dual channel micropower

2n A max input bias current ISL28270

instrumentation amplifiers (in-amps) and the ISL28470 is a Quad-channel in-amp optimized for low 2.4V to 5V single 110d B CMRR, PSRR supplies.

0.7µV/°C offset voltage temperature coefficient

All three devices feature an Input Range Enhancement

Single supply operation

the negative supply with only a slight degradation of the CMRR performance. The output operation is rail to rail. Rail-to-rail input and output (RRIO)

The ISL28273 is compensated for a minimum gain of 10 or Input is capable of swinging above V+ and below V- more. For higher gain applications, the ISL28270 and (ground sensing) ISL28470 are compensated for a minimum gain of 100. The

Output sources and sinks ±29m A load current

in-amps have bipolar input devices for best offset and

excellent 1/f noise performance. The amplifiers can be 0.5% gain error

operated from one lithium cell or two Ni-Cd batteries.

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 Ro HS compliant and compatible with both Sn Pb 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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
