DS1804Z-050

The DS1804Z-050 is a digital potentiometer used in data acquisition applications. It is designed to provide precise control of linear position and velocity. The DS1804Z-050 can be used in a variety of settings, including industrial automation, automotive and aerospace applications, audio, consumer and medical devices.

The DS1804Z-050 digital potentiometer provides a simple, low-cost solution for precise analog control of voltage and current, as well as precise positioning. This device has a 256-step linear resistor array that can be programmed in software. It is a low-voltage, low-power device that can be used in a variety of settings.

The working principle of the DS1804Z-050 is that the resistor array is driven by an input control voltage or current. An internal error amplifier compares the output of the resistor array with the control voltage or current, and feeds back an error signal to the R/W (Read/Write) register. The R/W register is then used to adjust the position of the selected resistor. This process is repeated until the error amplifier converges to an ideal voltage or current.

The linearity of the DS1804Z-050 digital potentiometer is extremely high, with a typical 0.3%, 0.5% or 0.8% linearity error, depending on the series and temperature range. The device is also very fast, with a switch time of 1.6 microseconds typical.

The DS1804Z-050 digital potentiometer is capable of handling high voltage and high power. The maximum voltage rating is 32 V and the maximum power rating is 2.5 W. For higher power/voltage applications, multiple devices can be connected together in a series/parallel configuration. This also allows for greater flexibility in the design.

The DS1804Z-050 digital potentiometer is functional in temperatures ranging from -40°C to 125°C. It is also designed to be EMI/RFI-immune and compliant with RoHS standards.

Due to its high precision and flexible design, the DS1804Z-050 digital potentiometer is ideal for data acquisition applications. It is a low-cost, low-voltage, low-power device that is reliable and easy to use.
