The AD7376 is one of the few high voltage, high-performance digital potentiometers on the market. This device can be used as a programmable resistor or resistor divider. The AD7376 performs the same electronic adjustment function as mechanical potentiometers, variable resistors, and trimmers with enhanced resolution, solid-state reliability, and programmability. With digital rather than manual control, the AD7376 provides layout flexibility and allows closed-loop dynamic controllability. The AD7376 features sleep-mode programmability in shutdown that can be used to program the preset before device activation, thus providing an alternative to costly EEPROM solutions. The AD7376 is available in 10 kΩ, 50 kΩ, and 100 kΩ options, and can operate with a single supply of 10 V to 15 V or a dual supply of ±10 V to ±15 V.
The AD7376 digital potentiometer from Analog Devices provides 128 programmable positions and supports both single‑supply (20‑30 V) and dual‑supply (±15 V) operation. It offers three resistance options (10 kΩ, 50 kΩ, 100 kΩ) and features a 3‑wire SPI‑compatible serial interface with low THD (0.006 %).
The datasheet includes detailed specifications, pin configurations, timing diagrams, typical performance curves, and application notes such as high‑voltage DACs, programmable power supplies, and audio volume control. Ordering information and mechanical dimensions are also provided.
