Board Design (NCS2540DTBEVB)

The evaluation board was designed for non−inverting op

amp configuration (See Figure 5). The input contains

termination resistor (usually 50

W). The input can also be

monitored through J1, J4, and J7. The evaluation board has

versatile loading options for the op amp, depending on the

user’s preference, it can be configured as capacitive load,

series resistance load, parallel resistance load, etc.
