... CMRR performance. The output operation is rail to rail. The ISL28273 is compensated for a minimum gain 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 ...

ISL28270 and ISL28470 input circuit is shown in Circuit 1A, and the ISL28273 input circuit is shown in Circuit 1B. ISL28273: to avoid offset drift recommended that the terminals of the ISL28273 are not overdriven beyond 1V and the input current must never exceed 5mA ...

... Application Information Product Description The ISL28270 and ISL28273 are dual channel micropower instrumentation amplifiers (in-amps) and the ISL28470 is a Quad-channel which delivers rail-to-rail input amplification and rail-to-rail output swing. The in-amps also deliver excellent DC and AC specifications while consuming only about 60µ ...

... CMRR is not degraded by any resistor mismatches. Hence, unlike a three op-amp and especially a two op-amp in-amp realization, the ISL28270, ISL28273 and ISL28470 reduce the cost of external components by allowing the use more tolerance resistors without sacrificing CMRR performance. The CMRR will be typically 110dB regardless of the tolerance of the resistors used ...

... The ISL28270, ISL28273 and ISL28470 are Dual-channel and Quad-channel op-amps. If the application only requires one channel when using the ISL28270, ISL28273 or less than 4-channels when using the ISL28470, the user must configure the unused channel(s) to prevent them from oscillating. The unused channel(s) will oscillate if the input and output pins are floating ...
