CXAO42106A/B/C is a high-end current sensing operational amplifier, which is widely used and flexible due to its maximum input offset voltage of 300 microvolts (CXAO42106 A) and maximum input bias current of 20 nanoamps. CXAO42106 detects the current by detecting the voltage across the external current detection resistor, and then the internal circuit amplifies this detection voltage by 20 times and converts it into a voltage with ground (GND) as the reference point, which is output at the OUT pin. The low input offset voltage allows CXAO 42106 to detect very small voltages, so a relatively small current detection resistor can be used, reducing the power consumption of the current detection resistor. The wide input voltage range, high precision, and wide operating temperature range make the CXAO42106 highly suitable for industrial control and power management applications. The working current of CXAO42106 is as low as 60 microamperes, and it can also be applied to low-power or battery powered situations. CXAO42106 adopts a 5-pin SOT-23 package.
