概述
Description
The AD5235BRUZ25 is a nonvolatile digital potentiometer from Analog Devices, offering 25 kΩ resistance with 1024 tap points. It features SPI-compatible interface for precise resistance adjustments and retains settings during power-off.
Key specifications:
- Resolution: 10-bit (1024 steps)
- Interface: SPI (up to 50 MHz)
- Memory: EEMEM for storing wiper positions
- Voltage range: ±2.25V to ±2.75V (dual-supply), 2.7V to 5.5V (single-supply)
- Package: 16-lead TSSOP
Applications include programmable gain amplifiers, calibration systems, and volume controls. Its nonvolatile memory ensures settings persist without power, making it ideal for robust, repeatable configurations.
For detailed specs, refer to the datasheet.
