Description
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.

KEY FEATUREs
• Analog control voltages from 3 V down to 0.0 V.
• High-speed microprocessor interface.
• Automatic fast/slow current decay control.
• Full-scale error ±1 LSB.
• Interfaces directly with TTL levels and CMOS devices.
• Fast conversion speed, 3 µs.
• Matches PBL 3771.
