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.
