10kΩ, 1024-tap digital rheostat with non-volatile memory
The MAX5483EUD+T is a single-channel, 10kΩ digital potentiometer configured as a rheostat, offering 1024 tap positions for fine-grained resistance setting. The linear taper suits applications requiring a uniform step response across the full range. Non-volatile memory retains the wiper position at power-up, eliminating the need for a host microcontroller to re-initialize the setting after each cycle — a fit for calibration-free designs in industrial or instrumentation gear.
Supply range, temperature stability, and wiper resistance
A typical temperature coefficient of 35 ppm/°C keeps the resistance drift under 0.35% over a 100°C swing, while the 50 Ω typical wiper resistance adds a fixed offset that can be calibrated out in precision divider circuits.
Package, interface, and compliance
Housed in a 14-TSSOP package with a surface-mount footprint, the MAX5483EUD+T communicates via a SPI-compatible interface or an up/down control scheme (U/D, INC, CS). The ±25% resistance tolerance is typical for digital pots in this class; the end-to-end resistance is trimmed at the factory.
