MAX5494ETE+

The MAX5494ETE+ is a 10bit dual non-volatile linear taper digital potentiometer in 16 pin TQFN package. The device combines a single 1024 position potentiometer and the internal programmable voltage dividers and variable resistors perform the function of a mechanical potentiometer but replaces the mechanics with a pin-configurable 3-wire serial SPI compatible interface. It is a 3 terminal variable resistor which is ideally suited for applications requiring low temperature coefficient voltage dividers such as low-drift, programmable gain amplifiers.

• Supply voltage range is 2.7V to 5.25V (single supply operation)
• Operating temperature range from -40°C to 85°C
• Dual ±2.5V supply operation
• Wiper position stored in non-volatile memory and recalled upon power-up
• Data rate up to 7MHz
• Ratiometric temperature coefficient of 5ppm/°C
• End to end resistance is 10Kohm at ±25% tolerance and temperature coefficient is 35ppm/°C
• 1.5µA (max) standby current
• Reliability of 50,000 wiper store cycles (TA = 85°C)
• Reliability of 50 years wiper data retention (TA = 85°C)
