2.4.1.1 Single-Ended Current Output

The first current-mode configuration creates a single-ended output from a single-ended input. The jumper settings for this configuration are listed in Table 2-3. The current output is calculated by the transfer function in Equation 5:

Equation 5. I O U T = 10 RSET × VIN

The default EVM value for RSET is 2.5kΩ.

XTR300EVM XTR300 Single-Ended Current Output Configuration Circuit DrawingFigure 2-2 XTR300 Single-Ended Current Output Configuration Circuit Drawing

Figure 2-3 shows how to setup the XTR300EVM in single-ended current output mode. Connect your load to TB4 between OUT+ and GND. Apply ±15V to V+ and V–. Connect a 5V signal to VIN. Measure the current through the load by putting a digital multimeter (DMM) in series with the load. The current though the load is approximately 20mA with the default board values.
