8-Bit Digital Pot Packs High-Performance EEPROM

Available in resistance values of 10 kW, 50 kW, and 100 kW, the AS1506 256- tap, SPI-interfaced nonvolatile digital potentiometer integrates EEPROM with a 150-year data retention at 85°C and the ability to sustain 10 million write cycles at 25°C, one million at 85°C. Operating from a single 2.7 to 5.5V supply, the device consumes a maximum of 500 nA during standby and 200 µA during operation including the CMOS write current. Other features include an INL of ±0.5 LSB, DNL of ±0.5 LSB, and a small, eight-pin TDFN package measuring 3 x 3 mm. AUSTRIAMICROSYSTEMS USA INC., Raleigh, NC. (919) 676-5292.
