Description of Operation and Application
Information
Product Description
The ISL28274 and ISL28474 provide both a micropower
instrumentation amplifier (Amp A) and a low power precision
amplifier (Amp B) in the same package. The amplifiers
deliver rail-to-rail input amplification and rail-to-rail output
swing on a single 2.4V to 5V supply. They also deliver
excellent DC and AC specifications while consuming only
60A typical supply current per amplifier. Because the
instrumentation amplifiers provide an independent pair of
feedback terminals to set the gain and to adjust the output
level, the in-amp achieves high common-mode rejection
ratio regardless of the tolerance of the gain setting resistors.
The instrumentation amplifier is internally compensated for a
minimum closed loop gain of 100 or greater.
Input Protection
The input and feedback terminals have internal ESD
protection diodes to both positive and negative supply rails,
limiting the input voltage to within one diode drop beyond the
supply rails. If overdriving the inputs is necessary, the
external input current must never exceed 5mA. An external
series resistor may be used as a protection to limit excessive
external voltage and current from damaging the inputs.
