The DS3902U-530+ from Analog Devices is a dual, nonvolatile, low temperature-coefficient, variable digital resistor. It offers 256 user-selectable positions for precise control.
This device operates over a wide supply voltage range of 2.4V to 5.5V and communicates via an I2C-compatible serial interface. The resistor settings are stored in non-volatile memory, ensuring persistence across power cycles. It is available in configurations of 30kΩ/50kΩ or 15kΩ/50kΩ, with a nominal tolerance of ±20% and a typical temperature coefficient of ±300ppm/°C.
The DS3902U-530+ is designed for applications such as optical transceivers, instrumentation, RF power amplifiers, and audio power-amp biasing. It serves as an ideal replacement for conventional mechanical-trimming resistors and DIP switches.
Packaged in an 8-pin µSOP (also referred to as 8-uMAX/uSOP), the device is suitable for surface mount applications. The operating temperature range is -40°C to +95°C.
