Analog Devices MAX5393 Product Info

• Dual, 256-Tap Linear Taper Positions
• Single +1.7V to +5.5V Supply Operation
• Low 12µA Quiescent Supply Current
• 10kΩ, 50kΩ, and 100kΩ End-to-End Resistance Values
• SPI-Compatible Interface
• Wiper Set to Midscale on Power-Up
• -40°C to +125°C Operating Temperature Range

The MAX5391/MAX5393 dual 256-tap, volatile, low-voltage linear taper digital potentiometers offer three end-to-end resistance values of 10kΩ, 50kΩ, and 100kΩ. Operating from a single +1.7V to +5.5V power supply, these devices provide a low 35ppm/°C end-to-end temperature coefficient. The devices feature an SPI interface.

The small package size, low supply voltage, low supply current, and automotive temperature range of the MAX5391/MAX5393 make the devices uniquely suitable for the portable consumer market and battery backup industrial applications.

The MAX5391/MAX5393 include two digital potentiometers in a voltage-divider configuration. The MAX5391/MAX5393 are specified over the -40°C to +125°C automotive temperature range and are available in a 16-pin, 3mm x 3mm TQFN and a 14-pin TSSOP package, respectively.
