NJU39612 is a dual 7-bit+sign; Digital-to-Analog Converter (DAC) developed to be used in micro stepping applications together with the dual stepper motor driver. The NJU39612 has a set of input registers connected to an 8-bit data port for easy interfacing directly to a microprocessor. Two registers are used to store the data for each seven-bit DAC, the eighth bit being a sign bit (sign/magnitude coding).
