AD5175 is a single-channel, 1024-position, digital rheostat with an I2C interface and 50-times programmable (50-TP) wiper memory. It has a nominal resistance of 10 kΩ, a working voltage range of 2.7~5.5 V, and a single-supply operation. It can be used for AC or bipolar operations.
The AD5175 provides a 10 kΩ nominal resistance with 1024 discrete steps, a temperature coefficient of 35 ppm/°C, and a ±15 % resistor tolerance stored in memory. It operates from a single 2.7‑5.5 V supply or dual ±2.5‑±2.75 V supplies, and includes a 50‑time programmable (50‑TP) memory for wiper position retention.
The device is offered in a 10‑lead LFCSP (3 mm × 3 mm × 0.8 mm) and a 10‑lead MSOP (3 mm × 4.9 mm × 1.1 mm) package, and is rated for an operating temperature range of –40 °C to +125 °C. It features an I²C‑compatible serial interface with standard‑mode 100 kHz and fast‑mode 400 kHz clock rates, and includes reset and shutdown functions for power management.
