2.3 Power Requirements

The power-supply connections for the LOG200EVM are provided through standard banana jack connectors J1, J2, and J3 at the top of the EVM. The LOG200EVM can be set up with a single unipolar supply or with dual bipolar supplies by setting jumper J9. Table 3-2 summarizes the pin definition for supply connector J1, J2, and J3 and the allowed voltage range for each supply connection when configured with either unipolar or bipolar supplies.

Table 2-2 LOG200EVM Supply-Range Specifications

Connector

Number		 Supply Connection Voltage Range
J1 (V+) supply Unipolar: +4.5 V to +12 V
Bipolar: +2.25 V to +6 V
J2 Ground 0 V
J3 (V-) Supply Unipolar: Do not Connect
Bipolar: –2.25 V to –6 V

The EVM is configured by default using bipolar supply by opening jumper J9. To configure the device with unipolar supply, set jumper J9 to shunt pin 1–2.

Figure 3-3 shows the J1, J2, and J3 standard banana supply connectors, and jumper J9 configuration.
