The ADA4830-1BCP-EBZ evaluation board makes it easy for designers to quickly observe the performance of the ADA4830-1 difference amplifier in real world applications. Input signals are applied through SMA jacks (INP, INN), and the output is taken from SMA jack VOUT. Power is applied through thre red +VS pin. The black GND pin should be grounded. The ADA4830-1BCP-EBZ inputs can be driven by either a balanced (differential) or unbalanced (single ended) source. For unbalanced signals, connect the unused input (INN) to ground at the signal source. The evaluation board is shipped with a 75ohm differential input termination at R5. The ADA4830-1BCP-EBZ board is configured with a 75ohm series resistor, installed at the output. This can be changed to match the actual load impedance. The Vref pin at the upper left of the board can be used to set the output bias voltage. It is internally biased to +VS/2 when this pin is floating.
