Introduction
This article discusses how to build a digital volume control circuit using the IC DS1668. This IC is commonly used in audio equipment and amplifiers for push-button up/down volume control functionality. The article provides an overview of the DS1668 and its features and discusses how to operate it.
The DS1668 and DS1669 Dallastats The DS1668 and DS1669 are electronic rheostats or potentiometers that provide 64 constant tap points over the resistive array. They are available in 10K, 50K, and 100K ohms variations. Let’s dive more to understand!
DS1668 and DS1669 Package Differences
The DS1668 and DS1669 differ in their package designs. The DS1668 is only available in a customized 6-pin package with a built-in push button for mechanical control input of the wiper point. In contrast, the DS1669 is offered in standard IC packages such as an 8-pin 300 mil DIP and an 8-pin 200 mil SOIC.
Operation
The DS1668/DS1669 Dallastats can be controlled through a contact closure input or by a digital base input. The DS1668 can operate from a single contact closure (pushbutton) input built into the customized 6-pin package or digital supply input (D). The DS1669 can be controlled using one push switch input, dual push switch inputs, or digital supply input.
