DS3503U+

The DS3503U+ is a non-volatile I²C stepper potentiometer in 10 pin µSOP package. It features two synchronized stepping digital potentiometers, one 7-bit potentiometer with RW as its output and another potentiometer with Y as its output. Both potentiometers reference the RH and RL terminals which can be stepped up and down by configuring the control registers. Programming is accomplished by an I²C compatible interface that can operate at speeds of up to 400KHz.

• Supply voltage range is 2.7V to 3.6V
• Operating temperature range from -40°C to 100°C
• Single linear taper potentiometer
• 128 wiper tap points
• Programmable logic lets WR step up and down with timing controlled by SYNC input
• Second potentiometer output pin (Y) centred at position 40h
• End to end resistance is 5Kohm at ±20% tolerance
• Ratiometric resistance temperature coefficient is ±4ppm/°C
• Peak current is 3mA
