... The ZXCT1021 is a precision high-side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1021 provides a fixed gain of 10 for applications where minimal sense voltage is required. The very low offset voltage enables a typical ...
