16 bit differential non-linearity is achieved with minimal trimming. SIMPLIFIED BLOCK AND TIMING DIAGRAM DB15-DB8 MSB Latch DB7-DB0 LSB Latch w w D Q Latch E .D w VREF 8 8 t a 16 S a VDD e h Two 8-bit latches (MSB latch and LSB latch) hold the 16-bit data which are converted by the DAC. A 16-bit bus can load both latches in one cycle. An 8-bit bus loads one latch at a time. By making the latches transparent (MSB latch = LSB latch = High) the DAC will continuously convert the BIT1 - BIT16 inputs. t e U 4 .c m o 16 RFB 16-Bit Multiplying DAC IOUT1 IOUT2 DATA LATCH OUTPUT D Q Latch E GND Rev. 2.00 1 w w w .D a S a t e e h U 4 t m o .c MP7626 ORDERING INFOR...
