VCC RL RL CC REQ CC REQ HEAD VEE Figure 2. Applications Diagram 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 Ω). 4. 5. 6. 7. REQ represents equivalent load resistance. For gain calculations RP = (RL × REQ)/(RL + REQ). Differential gain = 0.72 RP (±18%)(RP in Ω). Ceramic capacitors (0.1 µF) are recommended for good power supply noise filtering. http://onsemi.com 3 CS59201 PACKAGE DIMENSIONS SO–8 D SUFFIX CASE 751–07 ISSUE W –X– NOTES: 1.
