AD8341 Data Sheet Components Function Default Conditions
C2, C4, C7, Supply Decoupling. C2, C4, C7, C9, C14 = 0.1 μF C9, C14, C1, (Size 0603) C3, C8, C10, C1, C3, C8, C10 = 100 pF R2, R4, R5, R6 (Size 0603) R2, R4, R5, R6 = 0 Ω (Size 0603) R8, SW1 Output Disable Interface. The output stage of the AD8341 is disabled by applying a high R8 = 10 kΩ (Size 0603) voltage to the DSOP pin by moving SW1 to Position B. The output stage is enabled moving SW1 = SPDT (Position A, SW1 to Position A. The output disable function can also be exercised by applying an Output Enabled) external high or low voltage to the DSOP SMA connector with SW1 in Position A.
