Basic EVM Configuration
3 Basic EVM Configuration
This section describes four configurations for the XTR300EVM that enable evaluation of the basic XTR300
functions.
3.1 Voltage Mode Configurations
3.1.1 Single-Ended 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 4 . Connect your load to TB4 between OUT+ and OUT–.
Apply ±15 V to V+ and V–. Apply a 5-V signal to V
IN
. The voltage across TB4 should be 10 V. The voltage
output is calculated by the transfer function shown in Equation 1 :
