... Application diagram 1 Application diagram The TSC1021 high-side current-sense amplifier features a 2 input common-mode range that is independent of the supply voltage. The main advantage of this feature is that it allows high-side current sensing at voltages much greater than the supply voltage (V Figure 1. Application schematic: high-line current sensing ...

... TSC1021 5 Parameter definitions 5.1 Common mode rejection ratio (CMR) The common-mode rejection ratio (CMR) measures the ability of the current-sensing amplifier to reject any DC voltage applied on both inputs V back to the input so that its effect can be compared with the applied differential signal. The CMR is defined by the formula: 5 ...

... The actual value is very slightly different, mainly due to the effects of: ● the input offset voltage V ● the non-linearity, ● the voltage saturation of V The output voltage accuracy, expressed as a percentage, can be calculated with the following formula. with V/V for TSC1021A and V/V for TSC1021B. 8/12 ⋅ V out- sense , os and V ...
