3-channel 75Ω driver
BA7660FS
The BA7660FS is a 75Ω driver with a 6dB amplifier and three internal circuits, and provides 75Ω drive of composite Y signals and C signals, as well as RGB signals. Each load is capable of driving two circuits, and a sag correction function reduces the capacitance of the output coupling capacitor. The input voltage is within a range of 0V to 1.5V, enabling direct connection of ordinary D / A converter output. An internal power-saving circuit is also included which provides simultaneous muting on all three channels, and output pin shorting protection.
Applications • DVDs, set top boxes and other digital video devices
Features • 1) Can be coupled directly to D / A converter output. 2) Operates at a low power consumption (115mW typ.).
