DM13A Constant Current Sink Driver

Finally, no more ghosting on my large LED panels thanks to the built-in constant-current circuitry. The shift registers simplify my wiring layout so much I rewired a whole sign in one afternoon.

My old display was flickering like crazy until I swapped in this sink driver, now the shift registers handle the data cleanly and the constant current keeps everything rock steady. Exact performance I needed for the price.

Finally a driver that actually delivers steady brightness across my whole LED panel—the constant current circuitry works exactly as described. Hooked it up for a test run and the CMOS integration made wiring much cleaner than I expected. This thing handles the shift register and data latch duties wi
