The voltage of RNF pin and the external resistor (RRNF) determine the amount of output current. The internal high-precision amplifier (CMOS gate input) is used for the constant current control. If any resistance component exists in the wirings of RNF pin and the external resistor (RRNF), the precision can be reduced. To avoid this, pay utmost attention to the wirings. (1) Control (ⅰ)Register Control The constant current drive is executed by the output current value, the current direction and the current ON/OFF which are controlled by the register settings. (ⅱ)External Pin Control The constant current drive is executed by the output current value which is controlled by the register setting. Constant current driving direction and turning ON/OFF are controlled by INA/INB pin. Host Current value Direction ON/OFF CSB SCLK SDATA 3 VCM Control Logic SIF Current control DAC C.C.
