The DS1666-50 Digital Potentiometer devices are the latest generation of versatile, single-channel digital potentiometers devices. Available in the tiny SOT23-5 package, they are designed for both the single-ended and the bi-directional operation in applications requiring low voltage and low current.

The DS1666-50 are especially suited for automotive audio systems and portable battery powered devices. Their low current consumption makes them ideal for use in areas where space and power consumption are critical factors.

The DS1666-50 Digital Potentiometer is a two-terminal device that has its two terminals connected to a common node. The node is decoupled from the two terminals and the voltage is maintained between the two terminals by an internal voltage regulator.

The operation of the DS1666-50 is based on its internal mixed-signal circuitry. The device contains a digital potentiometer with a digital-to-analog converter which is controlled by a 16-bit digital word. The output of the device is set by positioning the wiper to one of 256 resistor settings.

The DS1666-50 is suitable for a variety of application fields such as digitally-controlled volume for audio, digital override for manual potentiometer systems, digitally adjustable resistance circuits, remote level setting, low noise/ripple operation, remote volume control, as well as low voltage/low current battery operation.

The DS1666-50 is mainly used in the application field of data acquisition, where a variable resistance that changes while the circuit is still operating is needed. The DS1666-50 allows the circuit designer to easily manipulate the resistance of the circuit without having to modify its physical components.

The DS1666-50 has a wide dynamic range and works with both AC and DC signals. The device can be powered with either batteries or a regulated DC power supply. The input voltage range is 1.8 – 5.5 V, while the output range is adjustable via the wiper position.

The working principle of the DS1666-50 is fairly straightforward. The device will store a 16-bit digital word in its onboard memory, which can be changed by the user. The device will then use this stored data to set the resistance of the potentiometer. The resistance will then be adjusted by the stored digital word and the wiper position.

In addition, the device features low power consumption and excess voltage protection, making it suitable for a wide range of applications.

The DS1666-50 Digital Potentiometer devices are the newest generation of versatile, single-channel, digital potentiometers. They are the perfect solution for applications that require low voltage and low current operations, such as automotive audio systems and portable battery powered devices. The device is mainly used in the application field of data acquisition, allowing the circuit designer to easily manipulate the resistance of the circuit without having to modify its physical components. With its wide dynamic range and low power consumption, the DS1666-50 is an ideal choice when dealing with resistance circuits.
