AD7376 +30 V/±15 V Operation 128-Position Digital Potentiometer

**The terms digital potentiometer and RDAC are used interchangeably.

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 14-lead TSSOP and 16-lead wide body SOIC packages in 10 kΩ, 50 kΩ, and 100 kΩ options. All parts are guaranteed to operate over the −40°C to +85°C extended industrial temperature range.
