The DS1807E+ from Maxim Integrated is a sophisticated dual logarithmic taper digital potentiometer designed to deliver precise digital control to a variety of applications. This compact and efficient device is an ideal solution for adjusting volume, contrast, and other parameters in a user-friendly manner.

Key features of the DS1807E+ include:

• Dual Potentiometer Channels: The device includes two independent potentiometer channels, each with 32 wiper positions, allowing for fine-tuned adjustments.
• Logarithmic Taper: The logarithmic taper provides a more natural adjustment curve for audio applications, mimicking the logarithmic response of the human ear to changes in volume.
• Serial Interface: It uses a 2-wire serial interface for communication, which is compatible with I²C, allowing for straightforward integration into existing designs.
• Wide Voltage Range: The DS1807E+ operates over a wide voltage range of 2.7V to 5.5V, making it suitable for both portable and fixed applications.
• Non-Volatile Memory: Wiper positions are stored in non-volatile memory, ensuring that settings are preserved even when the power is cycled.
• Low Power Consumption: Designed for power-sensitive applications, this digital potentiometer consumes minimal power, which enhances battery life in portable devices.

Applications for the DS1807E+ are diverse and include:

• Volume control in audio systems
• Brightness and contrast adjustments in video and display systems
• Parameter adjustments in automotive electronics
• Tunable filters and oscillators in communication devices

The DS1807E+ is available in a compact 14-pin TSSOP package, making it easy to incorporate into space-constrained designs. With its robust feature set and Maxim Integrated's reputation for quality, the DS1807E+ is a reliable choice for designers looking to add digital potentiometer functionality to their next project.
