Adc3Xjxx Input Coupling Configuration Resistors - Texas Instruments ADC3EVM User Manual

Introduction
1.5.2 ADC3xJxxEVM
The ADC34JxxEVM boards come with the THS4541RGT amplifiers installed. To operate the EVM in dc-
coupled mode, only the topside resistors must be changed. The output channels for dc-coupled signals
are B and C, and the resistors are located near the baluns of the channel, as shown in
Table 7 and the ADC34JxxEVM design files to change the appropriate resistors.
