Maximum permissible voltages on pins

The TSC1031 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 21 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.
