MAXIM INTEGRATED / ANALOG DEVICES DS1881E050 Digital Potentiometer
The DS1881E-050+ is a dual, non-volatile digital potentiometer in a 16-pin TSSOP package designed for audio applications at 5V signal levels. It features a log taper suitable for audio systems, with settings that can be stored in EEPROM for retention during power cycles. The device has separate power supplies for the potentiometers and communication circuitry, enabling clickless operation via zero-crossing detection to minimize audio artifacts. It provides channel matching and low harmonic distortion when driving high-impedance loads. The device operates within a supply voltage range of 4.5V to 5.5V, with an temperature range from -40°C to 85°C. It uses an I²C-compatible serial interface, offers 64 attenuation steps (1dB per step), and has configurable attenuation options. The total resistance is 45kΩ with a tolerance of ±20% and a temperature coefficient of 300ppm/°C. The potentiometer can be configured for volatile or non-volatile storage, with three address pins allowing up to 8 devices on an I²C bus. Common applications include signal processing, audio equipment, and portable devices.
