SLD2X1K000/9K000BQ

Resistor networks, arrays, and components are widely used in the electronics industry for signal conditioning, power management and energy conversion. The SLD2X1K000/9K000BQ series of digital potentiometers from Vishay incorporates a self-contained micro-controller that allows it to be used in complex applications requiring digital control of potentiometers’ resistance values.

The SLD2X1K000/9K000BQ is a two-element digital potentiometer that can be used to divide current into two parts: one part flowing through the fixed resistor and one part flowing through the adjustable resistor. The two resistors are connected in series and arranged in a series-parallel configuration. This provides a greater range of resistance values than if the resistors were connected directly in series. It also reduces the need to use multiple components, which reduces cost.

The SLD2X1K000/9K000BQ is Controlled by a Digital Interface (CDI), which is a serial communication protocol developed by Vishay. It allows the user to control the resistance of the SLD2X1K000/9K000BQ from an external source, typically a microcontroller or logic device. By virtue of its 300 kHz maximum operating speed and low power consumption, users can control the device with a low-cost, high-bandwidth communication protocol.

The SLD2X1K000/9K000BQ series includes an active tracking function. This feature monitors the resistance to detect any drift in resistance from the programmed values, and it automatically adjusts the resistance value to match the programmed value. The tracking feature ensures that the potentiometers maintain the desired resistance values over temperature and power supply variations.

The SLD2X1K000/9K000BQ provides a wide range of applications. It can be used in audio applications to control loudness, balance and frequency equalization. It can also be used for precise control of servo motors and actuators, as well as voltage and current regulation circuits. It is also suitable for calibrating and testing instrumentation, and in tachometer and speed control circuits.

The SLD2X1K000/9K000BQ is a robust device capable of operation in a wide range of temperatures and storage temperatures. It is available in 6-pin SOT-23 package for cost-effectiveness. The series also offers low-power consumption and high reliability, making it ideal for use in high-end products.
