DS3903E

IC DGTL POT 10K/90KOHM 20TSSOP

Manufacturer: Analog Devices Inc./Maxim Integrated

Categories: Digital Potentiometers

Quality Control: Learn More

The Analog Devices Inc./Maxim Integrated DS3903E is a triple-channel I2C-interface digital potentiometer, offering selectable resistance values of 10kO or 90kO. This device features 128 discrete tap points per channel, enabling precise analog output control. Designed for surface-mount applications, it is supplied in a 20-TSSOP package. The DS3903E operates with a supply voltage range of 2.7V to 5.5V and a typical power consumption of 250 Ohms resistance at the wiper. Its non-volatile memory ensures configuration persistence across power cycles. Applications for this component include industrial automation, consumer electronics, and medical devices where accurate analog signal adjustment is critical. The operating temperature range is -40°C to 85°C.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
