PBM 3960/1 is a dual 7-bit+sign, Digital-to-Analog Converter (DAC) especially
developed to be used together with the PBL 3771/1, Precision Stepper Motor  driver
in micro-stepping applications. The circuit 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). A second set of registers are used for automatic fast/slow current
decay control in conjunction with the PBL 3771/1, a feature that greatly improves
high-speed micro-stepping performance. The PBM 3960/1 is fabricated in a high-
speed CMOS process.

这个好像就是IR发射管,与红外传感器没有关系的东西
