The AD5251BRU1 is a dual 64-position digital potentiometer from Analog Devices with non-volatile memory (EEMEM). It uses an I²C serial interface for direct read/write access to the RDAC and EEMEM registers. The device offers a selectable address, allowing up to four devices on the same bus.
Key electrical specifications include 1 kΩ nominal resistance with ±30% tolerance, linear taper, 64 taps, and a temperature coefficient of 650 ppm/°C. It supports single supply operation from 2.7V to 5.5V or dual supplies from ±2.25V to ±2.75V. The bandwidth is 4 MHz (1 kΩ version).
The AD5251BRU1 is housed in a 14-TSSOP surface-mount package with a width of 4.40 mm. It operates over a temperature range of -40°C to 105°C. Non-volatile memory features include 100-year data retention at 55°C and 100,000 write endurance cycles, with a typical EEMEM rewrite time of 540 µs.
Single supply: 2.7V to 5.5V; dual supply: ±2.25V to ±2.75V.
