Frequently Asked Questions
What common-mode voltage range and rejection ratio does the INA201AIDGKRG4 support?
The INA201AIDGKRG4 supports an 18 V common-mode input voltage range with a minimum common-mode rejection ratio of 100 dB and a typical CMRR of 123 dB, enabling highly accurate high-side current sensing in 12 V and 18 V power rails without significant error from supply noise.
How does the input offset voltage of the INA201AIDGKRG4 affect precision current measurement?
With a maximum input offset voltage of 2500 µV and bias current as low as 0.01 µA at 25°C, the INA201AIDGKRG4 introduces minimal measurement error in current sensing circuits, making it suitable for applications that monitor small shunt resistor drops in the millivolt range across 8-pin VSSOP footprints.
Which power management designs benefit from the INA201AIDGKRG4 in an 8-pin VSSOP package?
Battery management systems, DC-DC converter current feedback loops, and motor driver protection circuits benefit from the INA201AIDGKRG4, as its 18 V range, 100 dB CMRR, and voltage-feedback amplifier with frequency compensation fit compactly in an 8-pin VSSOP package for space-constrained industrial and telecom boards.
When should engineers choose INA201AIDGKRG4 over a standard op-amp for high-side current sensing?
Engineers should select the INA201AIDGKRG4 when the sensing node sits at up to 18 V above ground, because its 100 dB minimum CMRR and 123 dB typical CMRR suppress common-mode interference far better than standard op-amps, while the integrated frequency compensation reduces the external component count required for stable operation in closed-loop current monitoring circuits.
