abstract
The invention discloses a wd television, which comprises an input end, a preprocessing stage circuit, an analog circuit, an analog-to-digital converter, a digital circuit and an output end, wherein a linear isolation amplifier is connected between the preprocessing stage circuit and the analog-to-digital converter. The linear isolation amplifier is connected between the preprocessing stage and the analog-to-digital converter, which blocks the * * * mode interference and differential mode interference from the pre-circuit part and improves the anti-interference performance; In addition, because the radiator is connected between the main chip and the aluminum alloy casing, there is no need for a fan, so the heat dissipation effect is better and wd tv is more stable.
