UNISONIC TECHNOLOGIES CO., LT L16B40 Preliminary CMOS IC 16-BIT CONSTANT CURRENT LE RIER WITH BUILT-IN TO ELIMINATE THE GHOSTING ESCRIPTION SSOP-24 UTC L16B40 is a new 16-bit cstant current LE driver IC with 20 output rating. Output currents with high accuracy and csistency can be preset through an external resistor. The output current ranges from 2mA to 40mA. Moreover, the fast current respse time and built-in to eliminate the ghosting make UTC L16B40 performing better in output current and display image. FEATURES * Built-in to eliminate the ghosting * Supply voltage range: 3.3 ~ 5.5 * Cstant output current range: 2 ~ 40mA * Output voltage: 20 (Max.) * Operating temperature range: -40 C ~ 85 C * Output current accuracy: ICs: ±3.0% (Typ.)
