Drawings Section DESCRIPTION The DS1801 is a dual audio taper potentiometer having logarithmic resistive characteristics over the device range.
Each potentiometer provides 65 wiper positions with a 1 dB increment per step and device mute.
The 3-wire serial interface, using a CPU, provides the user the ability of reading or writing exact wiper positions of the two potentiometers.
Additionally, the part contains a zero-crossing detection feature that minimizes noise resulting from wiper transitions.
Packages for the part include a 14-pin PDIP, 16-pin SOIC, and 14-pin TSSOP.
1 of 10 030300 DS1801 OPERATION The DS1801 provides two 65-position potentiometers per package, each having a logarithmic resistive characteristic as shown in Table 1.
The DS1801 is controlled by a 3-wire serial interface.
The 3-wire serial interface...
