Description and Introduction

8-Bit, 4-Channel Data Acquisition System The AD8401AR is a digital potentiometer manufactured by Analog Devices (AD). It is a single-channel, 256-position, digitally controlled variable resistor (VR) device. The key specifications include:

- **Resolution**: 8-bit (256 positions)
- **Resistance Values**: Available in 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ
- **Interface**: SPI-compatible serial interface
- **Supply Voltage**: 2.7 V to 5.5 V
- **Temperature Range**: -40°C to +125°C
- **Package**: 8-lead SOIC
- **Non-Volatile Memory**: Yes, it retains the wiper position during power-off
- **End-to-End Resistance Tolerance**: ±20%
- **Wiper Resistance**: Typically 50 Ω
- **Power-On Midscale Preset**: Yes, the wiper is set to midscale at power-on
- **Low Power Consumption**: Typically 1 µA in standby mode

These specifications make the AD8401AR suitable for applications requiring programmable resistance, such as in audio equipment, instrumentation, and industrial control systems.
