Dual Log Audio Digital Potentiometer
General Description
The DS1882 is a dual, nonvolatile (NV) digital poten-
tiometer designed to operate in audio systems that
accomodate up to ±7V signal levels. The potentiometer
settings can be stored in EEPROM so that they are
retained when the power is cycled. The DS1882 has
separate supplies for the potentiometers (V
CC
) and the
communication circuitry (V
DD
). For clickless/popless
operation, a zero-crossing detector allows the wiper
position to change when there is no voltage across the
potentiometer. The DS1882 is also designed to mini-
mize crosstalk, and the two digital potentiometers pro-
vide 0.5dB channel-to-channel matching to prevent
volume differences between channels. Total harmonic
distortion (THD) is also minimal as long as the wiper
drives a high-impedance load.
Two attenuation configuration options provide optimum
flexibility for the specific application. Configuration
Option 1 provides 63 logarithmic tapered steps (0dB to
-62dB, 1dB/step) plus a mute setting. Configuration
Option 2 has 32 logarithmic steps plus mute and pro-
vides software compatibility with the DS1808. When
Configuration Option 2 is used in combination with the
16-pin SO package, the DS1882 is both software and pin
compatible with the DS1808 in 5V applications.
