Maximum permissible voltages on pins

The TSC103 can be used in either single- or dual-supply configuration. The dual-supply

configuration is achieved by disconnecting Vcc- and Gnd, and connecting Vcc- to a negative

supply. Figure 8 illustrates how the absolute maximum voltages on input pins Vp and Vm are

referred to the Vcc- potential, while the maximum voltages on the positive supply pin, gain

selection pins and output pins are referred to the Gnd pin. It should also be noted that the

maximum voltage between Vcc- and Vcc+ is limited to 15 V.
