... CMRR performance. The output operation is rail-to-rail. The ISL28271 is compensated for a minimum gain more. For higher gain applications, the ISL28272 is compensated for a minimum gain of 100. The in-amps have CMOS input devices for maximum input common voltage range. The amplifiers can be operated from one lithium cell or two Ni-Cd batteries ...

... Negative Feedback high impedance terminals. The FB- pins connect to an Circuit 1B external resistor divider to individually set the desired gain of the in-amp. ISL28272 input circuit is shown in Circuit 1A, and the ISL28271 input circuit is shown in Circuit 1B. ISL28271: to avoid offset drift recommended that the terminals of the ISL28271 are not overdriven beyond 1V and the input current must never exceed 5mA ...

... Because the independent pair of feedback terminals set the gain and adjust the output zero level, the ISL28271 and ISL28272 achieve high CMRR regardless of the tolerance of the gain setting resistors. The ISL28271 is internally compensated for a minimum gain of 10 ...

... VOUT TotalGainError TotalGainError Disable/Power-Down The ISL28271 and ISL28272 have an enable/disable pin for each channel. They can be powered down to reduce the supply current to typically 4µA when all channels are off. When disabled, the corresponding output high impedance state. The active low EN pin has an internal pull down and hence can be left floating and the in-amp enabled by default ...

... Unused Channels The ISL28271 and ISL28272 are Dual channel op amps. If the application only requires one channel when using the ISL28271 or ISL28272, the user must configure the unused channel to prevent it from oscillating. The unused channel will oscillate if the input and output pins are floating. This will result in higher than expected supply currents and possible noise injection into the channel being used ...
