Working Principle

The TLV5619IDW converts digital codes into an analog voltage output using an internal voltage-output DAC and precision output amplifier. The analog voltage output is proportional to the digital code. This converter has an 8-bit parallel data interface and its output code can be completely specified using 8-bit values sent over the 8-bit parallel data bus. This simplifies the process of interfacing with microcontrollers and digital-to-analog interfaces.

The TLV5619IDW contains an onboard voltage reference of 2.5V, 5V, or 10V. This voltage reference is used to configure the converter’s output range. In addition, an internal adaptive current offset suppression circuit is used to reduce output offset errors due to external component variation and temperature changes.

The TLV5619IDW also features a current output capability that allows the converter to be used as a low-power source of positive or negative current. This feature can be used in applications requiring the precise control of current sources, such as the control of switching arrays and linear actuators.

In summary, the TLV5619IDW is a component that excels in its performance and accuracy and is ideal for precision data acquisition systems.
