MAX5437EUD+

The MAX5437EUD+ is a ±15V low drift digital potentiometer in 14 pin TSSOP package. This device is a single 128 position high voltage digital potentiometer which performs the same function as mechanical potentiometer but replace the mechanics with a simple digital interface. It includes an on-chip high voltage uncommitted amplifier providing additional reduction in board space and cost. The resistor string uses its own analogue supplies (VDD and VSS) that require VDD - VSS to be greater than 9V and less than 31.5V which allows for greater flexibility in voltage ranges that can be used with the device.

• Supply voltage range is 10V to 30V (single supply operation)
• 28V to -10V single negative supply operation
• ±5V to ±15V dual supply operation
• Operating temperature range from -40°C to 85°C
• Power-on reset, wiper goes to midscale (position 64)
• Ratiometric temperature coefficient of 5ppm/°C
• End to end resistance is 50Kohm at ±25% tolerance and temperature coefficient is 35ppm/°C
• Glitchless switching between resistor taps
• 3-wire SPI/QSPI/MICROWIRE compatible serial interface
