Overview
The BA7612N is a three-channel analog multiplexer with integrated mute, 6dB amplifier, and 75Ω driver. Designed for video cassette recorders and televisions, it features a wide operating supply voltage range of 4.5V to 13.0V. The device offers low power dissipation of 103mW typical, excellent frequency characteristics up to 10MHz, and a large dynamic range of 3.5V peak-to-peak. It provides low interchannel crosstalk of -65dB at 4.43MHz and high input impedance of 20kΩ. The component utilizes an SIP-8 package.
Feature Summary
- Three-input to one-output switching capability
- Integrated 6dB amplifier and 75Ω driver stage
- Built-in mute functionality
- High input impedance termination
Applications
- Video cassette recorders
- Televisions
Procurement Notes
Verify the current lifecycle status as the component may be discontinued or subject to limited availability. Confirm that the SIP-8 through-hole package matches the target PCB footprint. Ensure the 4.5V to 13.0V supply voltage range aligns with the system design requirements before finalizing procurement.
Selection Notes
Select this component for applications requiring a compact solution for routing multiple video signals. The built-in 6dB gain and 75Ω driver simplify circuit design by reducing external component count. Verify that the 103mW power dissipation fits within the thermal constraints of the enclosure.
Part Context
This part belongs to ROHM Semiconductor's multimedia IC portfolio, specifically designed for consumer electronics. It serves as a signal switcher for analog video paths. The device integrates control logic and amplification stages into a single SIP-8 package to optimize board space.
Replacement Considerations
The BA7612F is a pin-compatible alternative with a restricted supply voltage range of 4.5V to 9.5V. Verify that the lower maximum voltage limit of the replacement does not exceed the system's operating conditions.
FAQ
What is the recommended output matching resistor?
An external resistor of 43Ω should be connected to ensure proper output matching, as the internal output impedance is approximately 32Ω.
How is the CTL pin switching level defined?
The switching level is the voltage at which the output drops below 20mV peak-to-peak when the input signal is a 1VP-P sine wave at 1MHz.
What is the typical interchannel crosstalk performance?
The typical interchannel crosstalk is -65dB when measured at a frequency of 4.43MHz with a 1VP-P input signal.
