AD8667AST Datasheet
AD8667AST Price current provided by the lamp-current programmer circuit. A single capacitor on the CCFL Vc pin provides both stable loop compensation and an averaging function to the half- wave-rectified sinusoidal lamp current. Therefore, input prog ramming current relates to one-half of average lamp current. This scheme reduces the number of loop com- pensation components and permits faster loop transient response in comparison to previously published circuits. If a floating lamp configuration is used, ground the Dl0 pin. 256 bytes of RAM, 768 bytes of AUX-RAM, and a 128 bytes special function area. These can be addressed each in a different way (see also Table 2). - RAM 0 t0 127 can be addressed directly and indirectly as in the 80C51. Address pointers are RO and Rl of the selected registerbank. ( 8 P ) o S V \ I u ! P O J a t v \ o d a l q q S L u n L u ! x P y y ( 8 P ) O V V \ I u ! P O J a t v \ o d a l q P I !
