The MAX5407EKA is a digital potentiometer designed for audio applications, offering features like volume control and fading/balancing of audio signals. It functions similarly to a mechanical potentiometer but is digitally controlled via a 2-wire serial interface.
This device has a fixed end-to-end resistance of 20k Ohms and features 32 tap points with 1dB steps between taps. The logarithmic taper makes it suitable for audio level adjustments. It operates on a single supply voltage ranging from +2.7V to +5.5V and consumes a low supply current of 0.35µA.
Key features include zero-crossing detection to minimize audible clicks during wiper transitions and a power-on reset function where the wiper defaults to maximum attenuation. The MAX5407EKA is housed in a compact 8-pin SOT-23 package, measuring 3mm x 3mm, and is guaranteed for operation within a temperature range of -40°C to +85°C.
Its nominal resistor temperature coefficient is 35ppm/°C end-to-end and 5ppm/°C ratiometric. The simple Up/Down serial data interface simplifies integration into designs.
