2.4.2.1 Single-Ended Voltage Output

The first voltage mode configuration creates a single-ended output from a single ended input. The jumper settings for this configuration are listed in Table 2-5. The voltage output is calculated by the transfer function shown in Equation 12:

Equation 12. V O U T = RG × VIN 2 × RSET

The default EVM configurations set RG to 10kΩ and RSET to 2.5kΩ.

Figure 2-7 shows how to setup the XTR300EVM in single-ended voltage output mode. Connect your load to TB4 between OUT+ and OUT–. Apply ±15V to V+ and V–. Apply a 5V signal to VIN. The voltage across TB4 must be 10V with the default board values.
