Linear LED Drivers eliminate need for external components.
Occupying 3 x 3 mm board space, 2-channel SP7120 and 3-channel SP7122 multichannel drivers feature channel-to-channel matching of 0.8% typical with 3% absolute current accuracy. Drivers are factory programmed in fixed 15, 20, or 25 mA current outputs which are designated by an A, B, or C, respectively, in part number suffix. Available in Pb-free SPT 23-6 package, devices are specified over -40 to...
