Unterpremstaetten, Austriaaustriamicrosystems has expanded its digital potentiometer portfolio with the AS1506, a 256-tap SPI-interfaced nonvolatile device available with 10-, 50- and 100-kOhms resistance.
Operating from a single supply from 2.7 to 5.5V the AS1506 offers an end-to end resistance temperature coefficient of 90ppm/°C. The AS1506 delivers integral nonlinearity (INL) of ±0.5LSB (max) as well as differential nonlinearity (DNL) of ±0.5LSB (max).
The AS1506 digital potentiometer stores the wiper information in an integrated (High Endurance, Performance & Retention) EEPROM. austriamicrosystems Hi-EPR EEPROM allows 10 million write cycles at 25°C and 1 million write cycles at 85°C. Additionally, the AS1506 delivers 150 years of data retention at 85°C.
The AS1506 is available in an 8-pin TDFN 3x3mm packaging.
