The NSCSA21xA-Q1 series are micropower, precision current sense amplifier with a very wide input common mode range. The NSCSA21xA-Q1 monitors bidirectional current via the voltage across an external sense resistor. The input common mode voltage range extends from –2V to 28V, with respect to the negative supply voltage (V–). This allows for the NSCSA21xA-Q1 to be used for both low and high side current-sensing applications.Four fixed gains are available: 50 V/V, 75 V/V, 100 V/V or 200 V/V. The four gain selections offer flexibility in the choice of the external current-sense resistor. The very low ±5μV (typ) input offset voltage allows small 25mV to 100mV full-scale VSHUNT voltage for very low Very low power loss at full-current measurement.
The NSCSA21xA-Q1 series operates from a single 2.7V to 28V supply, drawing a typical of 230μA of supply current. It is specified operating temperature range from -40°C to 125°C, and is offered in a space-saving SC70-6 package.
