TPL0401B-10DCKR Integrated Circuits (ICs)

The TPL0401B-10DCKR is a digital potentiometer that belongs to the data acquisition class of devices. It is a 4-terminal electronic device which can adjust its resistance value depending on the input applied to the 2 control terminals. The device is an example of a monolithic dual digital potentiometer that consists of a variable resistor array (RA) and a wiper buffer amplifier (BUF). It accurately steps the resistance value between low and high terminals from 0Ω to 10kΩ when using different voltages from the control terminals.

The TPL0401B-10DCKR is composed of two linear potentiometers, each having its own control terminals. The design provides a wide range of applications since the user can adjust R0, the fixed resistance between the wiper and low terminal, and R1, the fixed resistance between the wiper and high terminal. As the voltage at the control terminals (VC1 and VC2) are varied, the wiper resistance increases continuously between R0 and R1. The wiper current flows between the low and high terminals, resulting in an adjustable resistance.

The device also includes additional circuits such as built-in REF buffer and Wiper Driver which help to further improve its performance. The REF buffer generates a zero reference voltage while the Wiper Driver adjusts the resistance level of the wiper to the desired level. The device is constructed in three different packages, the single-inline package (SIP) with the least components, the dual in-line package (DIP) with more components, and the surface mount package (SMP) with the highest component count.

In its application field, the TPL0401B-10DCKR is widely used in tuning circuits and circuit adjustment. Its adjustable resistance makes it suitable for motor control, audio input impedance control, and low-voltage power supplies. It can also be used in voltage and current measurement, temperature control, and LED lighting control. It is a versatile device that can be used for a variety of tasks.

The TPL0401B-10DCKR works by adjusting its resistance value with the use of the 2 control terminals (VC1 and VC2). As the voltage at these terminals is varied, the wiper resistance increases or decreases between R0 and R1. The device also includes additional circuits such as REF buffer and Wiper Driver which help to further improve its performance. These components, combined with the excellent linearity and low noise levels, allow the device to be used in various application fields.
