概述
Description
The AD8402ARU10 is a dual-channel, 10-bit digital potentiometer from Analog Devices. It features non-volatile memory, retaining settings during power-off, and operates with a 10 kΩ end-to-end resistance.
Key features:
- Dual-channel: Two independent potentiometers in one IC.
- SPI-compatible interface: Simple digital control.
- Low power consumption: Suitable for battery-powered devices.
- Wide voltage range: 2.7V–5.5V operation.
Applications include programmable gain amplifiers, volume control, and calibration circuits. The AD8402ARU10 comes in a 16-lead TSSOP package, making it compact for space-constrained designs.
For detailed specs, refer to the datasheet on Analog Devices' website.
