LED DRVR 2-CH 1.4V 0.04A 22-Pin SOP Embossed T/R

The BA6820F is a two-channel, 12-point LED drivers for VU-scale bar-level meters. The ICs are available in 22-pin SOP packages, and use a dynamic-drive system that can drive two 12-point displays. The ICs have independent AC and DC inputs, and the AC input mode has a peak hold circuit (with cancel function). The ICs also feature a power-on mute, so steps to prevent erroneous LED lighting at power on are not required. The input resistance of the AC inputs is 3k? (Typ.) for the BA6820F.

• Uses dynamic-drive system to display two 12-point channels. 22-pin SOP and 22-pin shrink DIP packages.
• Independent AC and DC inputs provided (one input displays one channel). Switching function allows two-mode display.
• Upper 8 points have peak hold function in AC mode (two seconds). A peak-hold cancel function is also provided.
• A mute function is provided, and muting can be applied externally.
• Power on mute function.
• Power Dissipation: 450mW
