BA7612F

Multimedia ICs Video signal switcher BA7612N / BA7612F The BA7612N and BA7613F are three-channel analog multiplexers with built-in mute, 6dB amplifier and 75Ω driver. The ICs designed for use in video cassette recorders, and feature a large dynamic range and wide operating frequency range. All inputs are terminated with 20kΩ (Typ.) input impedance. Applications Video cassette recorders and televisions Features 1) 3-input / 1-output switches. 2) 3) 4) 5) Built-in 6dB amplifier and 75Ω driver. Built-in mute. Large input impedance (20kΩ Typ.). Wide operating supply voltage range (4.5V ~ 13.0V BA7612N) (4.5V ~ 9.5V BA7613F). 6) Low power dissipation (103mW Typ.). 7) Excellent frequency characteristics (10MHz, 0dB Typ.). 8) Wide dynamic range (3.5VP-P Typ.). 9) Low interchannel crosstalk ( – 65dB Typ., f = 4.43MHz).
