Data Acquisition - Digital Potentiometers is an important element in modern electronic circuits and is widely used in various applications. AS1507-BTDT-100-1K is a Digital Potentiometer that stands out from the others due to its many features.

Digital Potentiometers work by varying resistance in digital form, with a single common pin replacing the traditional 2-pin potentiometer setup. It contains a virtual “wiper” whose position can be adjusted by sending a current into the terminal of the wiper pin. The resistance between the digital potentiometer source (analog output) and the wiper terminal is digitally adjusted by the current sent. The wiper can then be connected to any of the digital potentiometer outputs.

The AS1507-BTDT-100-1K is a single-channel digitally programmable potentiometer which can be connected to 1-Wire Serial EEPROM. This potentiometer has a resolution of 6-bit, with an adjustable resistance range between 100 kΩ to 10MΩ. Its operation is rated for 5V power supply and can operate over an extended temperature range (from -40°C to +85°C). It supports two resistance settings, two tap setting members, and a revision command.

Having a low noise floor and high accuracy, the AS1507-BTDT-100-1K is thus well-suited for applications like analog-to-digital converter offset calibrations, trimming digital potentiometers, or setting gain references. This Digital Potentiometer is ideal for building automated test equipment (ATE) where precision and accuracy are critical parameters.

The AS1507-BTDT-100-1K is also energy efficient, with low supply current (1mA max) and standby current (0.2mA max). In addition, its EEPROM memory feature supports an energy-saving auto-wakeup system. This feature essentially enables the device to automatically activate itself when the wiper is engaged, eliminating the need for a dedicated power source.

In summary, the AS1507-BTDT-100-1K is a powerful and reliable digital potentiometer that meets the requirements of many applications. Its small package size, low power consumption, high accuracy, and wide operating temperature range make it the perfect choice for a variety of applications. With its easy to use interface and wide variety of features, this Digital Potentiometer is a must have for any engineer who needs an efficient and reliable solution.
