The MAX5407 SOT-PoT™ is a logarithmic taper digital potentiometer with 32 tap points that has 1dB steps between taps. This device is ideal for audio applications, such as volume control and fading/balancing audio signals.
The MAX5407 consists of a resistor string and CMOS switches that are digitally controlled through a simple 2-wire serial interface. This device performs the same function as a mechanical potentiometer. The device has a fixed end-to-end resistance of 20kΩ and features zero-crossing detection to minimize the audible noise generated by the wiper transitions.
This device has nominal resistor temperature coefficients of 35ppm/°C end-to-end and 5ppm/°C ratiometric. The MAX5407 is available in a space saving 8-pin SOT23 package and is guaranteed from -40°C to +85°C.
Applications
- Audio Volume Control
- Fading/Balancing Audio Signals
- Mechanical Potentiometer Replacements
