General Description
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 applica-
tions, 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 20k
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 Replacement
