Dual NV Audio Taper Digital Potentiometer

General Description

The DS1881 is a dual, nonvolatile (NV) digital poten-

tiometer designed to operate in audio systems that

require 5V signal levels. The potentiometer settings can

be stored in EEPROM so that they are retained when the

power is cycled. The DS1881 has separate supplies for

the potentiometers (V

) and the communication circuit-

ry (V

). For clickless/popless operation, a zero-crossing

detector allows the wiper position to change when there

is no voltage across the potentiometer. The device is

also designed to minimize crosstalk, and the two digital

potentiometers provide 0.5dB channel-to-channel match-

ing 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 DS1881 is both software and pin

compatible with the DS1808 in 5V applications.
