Produktbeskrivning
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 20kohm 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
Miniature 3mm x 3mm 8-Pin SOT23 Package
Logarithmic Taper with 1dB Steps Between Taps
32 Tap Positions
Low 0.35µA Supply Current
+2.7V to +5.5V Single-Supply Operation
Zero-Crossing Detection to Minimize Audible
Clicks During Wiper Transitions
Simple Up/Down 2-Wire Serial Data Interface
Power-On Reset
Wiper Goes To Maximum Attenuation (Lowest Tap Position)
20kohm End-to-End Resistance
