The THS6232RHFEVM is equipped with SMA connectors for easy connection of signal generators and analysis equipment. As shipped, the EVM is configured for a gain of 10V/V, split-supply, differential input and output with 50Ω termination. By default, the inputs INA and INB are configured for a differential input connection. To use the device with a single-ended input, either use an external transformer or populate transformer T2 on the board, remove R21, populate R23 with a 0Ω resistor, and use INA as the single-ended input. OUTA (J2) is the output connector for single-ended output signals. The output resistors R8 and R13 in combination with the transformer (T1) on the amplifier output provide a 2.5Ω series resistance for PLC applications to the amplifier. There are several pads between the R8 and R13 resistors and the T1 output transformer. These pads are available for use as output attenuation, matching networks, and so forth. Users can change R8 and R13 to align with the desired application (for example DSL, PLC, solar rapid shutdown). For lab applications with bench instruments, R8 and R13 can be changed to provide a 25Ω load to the amplifier when terminated in 50Ω differentially (via T1 transformer). Resistors R8 and R13 must change to 24.9Ω from 2.49Ω to interface with lab instruments without additional loading or attenuation. To use the EVM with a single-ended output, remove resistor R18 and populate resistor R20 with 0Ω, which gives a single-ended output on OUTA. The EVM contains provisions for additional output devices to change the loading of the amplifier and to add protection devices. A common implementation for PLC measurements is to utilize a pi-attenuator to load the amplifier for PLC measurements. See the applications section, schematics, and layouts for more detail and how to reconfigure the EVM in the THS6232 7V-to-40V, Differential HPLC Line Driver With Common-Mode Buffer data sheet.
