4 Power-Supply Connections

The power-supply connections for the INA851EVM are provided through connector J1 at the top of the EVM. The positive power-supply connection is labeled +VCC, the negative power-supply connection is labeled –VEE, and the ground connection is labeled GND. To connect power to the INA851EVM, insert wires into each terminal of J1 and then tighten the screws to make the connection. Table 4-1 summarizes the pin definition for supply connector J1 and the allowed voltage range for each supply connection.

Table 4-1 INA851EVM Supply-Range Specifications
Pin Number Supply Connection Voltage Range
J1.3 Positive supply (+VCC) Single supply, VS = (+VCC): 8 V to 36 V
Dual supply, VS = (+VCC) – (–VEE): 4 V to 18 V
J1.2 Ground 0 V
J1.1 Negative supply (–VEE) Single supply, VS = (+VCC): 0 V (GND)
Dual supply, VS = (+VCC) – (–VEE): –4 V to –18 V

Figure 4-1 shows the INA851EVM voltage supply connections.
