Audio-grade digital pot with logarithmic taper
The Maxim Integrated MAX5410EEE+ is a dual-channel digital potentiometer with a logarithmic taper, 10kΩ end-to-end resistance, and 32 wiper taps per channel. The logarithmic taper is designed for audio volume and gain control applications where the human ear's logarithmic response is matched by a log-taper attenuator. The part communicates via an SPI interface and includes mute and zero-cross sense features to reduce audible clicks during wiper transitions. Housed in a 16-QSOP package (3.90 mm width), it operates over the industrial temperature range of -40°C to +85°C.
The 32 taps per channel give a step per tap in a log-scale volume control. The 10kΩ end-to-end resistance is a standard value for audio line-level signal paths.
