MAX5486
Stereo Volume Control with Pushbutton
Interface
General Description
The MAX5486
dual 40kΩ
logarithmic taper volume control
features a debounced pushbutton up/down interface that
controls volume and balance in audio applications. Each
potentiometer has 32 log-spaced tap points with a buffered
wiper output to replace mechanical potentiometers. An inte-
grated bias generator provides the required ((V
DD
+ V
SS
)/2)
bias voltage, eliminating the need for costly external op-amp
circuits in unipolar audio applications. A mode-indicator
LED output indicates volume or balance control. Five inte-
grated LED drivers indicate volume level or balance settings,
depending on the status of the mode indicator.
Use the MAX5486 digital inputs with momentary contact
single-pole/single-throw (SPST) pushbutton switches.
Each input includes internal debounced circuitry and a
pullup resistor to V
LOGIC
.
The MAX5486 advances the wiper setting once per but-
ton push. Maxim’s proprietary SmartWiper™ control elimi-
nates the need for a microcomputer to increase the wiper
transition rate. The accelerated auto-advance feature pro-
vides a wiper-changing rate at 4Hz for holding the control
input low for more than 250ms and at 8Hz after 500ms
and then at 11Hz after 1000ms (see Table 2).
All of the MAX5486’s pushbutton inputs are debounced.
The mute input allows a single pushbutton to change
between volume control and the -90dB (typ) mute setting.
The mode input toggles between volume and balance
control. The click-and-pop suppression feature minimizes
the audible noise generated by wiper transitions. The
typical total harmonic distortion plus noise (THD+N) for
the device is 0.003%. The MAX5486 provides a nominal
temperature coefficient of 35ppm/°C end-to-end and
5ppm/°C ratiometrically and a nominal resistance of 40kΩ
per potentiometer. The MAX5486 is available in a 24-pin
TSSOP package and is specified for operation over the
-40°C to +85°C extended temperature range.
