产品概述
DS1267BS-010+T/R is a dual digital potentiometer. The DS1267B dual digital potentiometer chip consists of two digitally controlled, solid-state potentiometers. Each potentiometer is composed of 256 resistive sections. Between each resistive section and both ends of the potentiometer are tap points that are accessible to the wiper. The position of the wiper on the resistive array is set by an 8bit value that controls which tap point is connected to the wiper output. Communication and control of the device are accomplished via a 3-wire serial port interface. This interface allows the device wiper position to be read or written. It can be connected in series (or stacked) for an increased total resistance with the same resolution. For multiple-device, single-processor environments, this device can be cascaded or daisy-chained. This feature provides for control of multiple devices over a single 3-wire bus.
