Dual Digital Potentiometers (DP) with 256 Taps and SPI Interface DP7261 FEATURES Two linear-taper digital potentiometers 256 resistor taps per potentiometer End to end resistance 50kŸ or 100kŸ Potentiometer control and memory access via SPI interface Low wiper resistance, typically 100 Nonvolatile memory storage for up to four wiper settings for each potentiometer Automatic recall of saved wiper settings at power up 2.5 to 6.0 volt operation Standby current less than 1µA 1,000,000 nonvolatile WRITE cycles 100 year nonvolatile memory data retention 24-lead SOIC and 24-lead TSSOP Industrial temperature range Industrial temperature range For Ordering Information details, see page 14. DESCRIPTION The DP7261 is two Digital Potentiometers (DPs) integrated with control logic and 8 bytes of NVRAM memory. Each DP consists of a series of resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper output.
