Recommended Load Conditions 1. Input must be AC coupled. 2. CC's are AC coupling capacitors. 3. RL's are DC bias and termination resistors, (recommended 130 ).
4. 5. 6. 7.
REQ represents equivalent load resistance. For gain calculations RP = (RL x REQ)/(RL + REQ). Differential gain = 0.72 RP (18%)(RP in ). Ceramic capacitors (0.1 F) are recommended for good power supply noise filtering.
