Digital potentiometers (DPot) are electronic components that replicate the variable resistance of a physical potentiometer. They are becoming increasingly popular due to their ability to more easily and efficiently control analog parameters such as voltage and current. DPot come in two varieties: single-ended and differential. The DS1858E-050+ is an integrated differential DPot that has been designed to meet the needs of high-precision applications.The DS1858E-050+ combines two wiper elements, precision voltage reference, and current switching logic on a single 16-pin SSOP package, giving it the advantage of minimal board space and integration benefits. This makes it a great choice for applications requiring precise adjustments and a low total system cost.The DS1858E-050+ can be used for a variety of tasks, including gain control in amplifiers, volume control in audio equipment, or setting the direction and amount of current or voltage in power supplies. It has a high voltage rating of up to 36V, making it suitable for use in battery-powered systems. The device’s power-on reset circuit ensures that all registers are held at a known state during power-up and that the wiper will remain in its current state until an update command is issued.The device can be controlled either through serial communications or through a two-wire bus interface. Through the two-wire bus, the device can be controlled by a microcontroller, such as an Arduino, or other logic-level devices. The serial communications interface supports standard I2C, SPI, and Microwire protocols. This makes the device compatible with most microcontrollers and embedded systems development platforms.The DS1858E-050+ DPot is a cost-effective way to precisely control analog parameters in a wide range of applications. Its ability to be controlled either through a two-wire bus or serial communications offers designers great flexibility, while the low-power, robust design ensures that the device will perform reliably for years to come.
