The LTC2636CDE-LMI10#TRPBF is a 2.7V to 5.5V low power 16-bit current-output digital-to-analog converters (DACs) that provide industry leading accuracy, temperature drift and performance in a compact 5-lead SOT-23 package. This DAC is designed for applications requiring precise control of digital voltages, currents or temperatures. It is suitable for use in systems such as industrial process control, audio and video circuitry, digital laser printer calibration and frequently used in mobile phones, battery powered applications and automotive applications.

The LTC2636CDE-LMI10#TRPBF is optimized for a wide variety of output current applications, from 5μA to 10mA. All digital inputs are CMOS compatible and the output current will remain in regulation while transitioning through logic levels, providing glitch-free bidirectional control of up to four independent output currents. This device also features a high accuracy internal reference and an external reference enable pin. The device includes a Power-on Reset (POR) circuit with an enable pin that sets the output to a known state.

The LTC2636CDE-LMI10#TRPBF can be operated with a single 2.7V to 5.5V supply. Output current is adjusted by writing a single 16-bit serial word to the device. Both the command and data words are transmitted MSB first through the serial data port. The output current can be changed dynamically in the DAC, allowing for fast and precise control of the output. The device also features a power-on-reset circuit that ensures that the DAC output always starts up in a known state. The device can be designed to provide very precise output current control even with small digital steps.

In terms of applications, the LTC2636CDE-LMI10#TRPBF is used in a wide variety of digital-to-analog applications, including process control and calibration, audio and video circuitry, digital laser printer calibration, batteries and automotive applications. The device is ideal for applications requiring precision and high accuracy. The on-chip integrated reference provides excellent linearity and accuracy even at high operating temperatures. The device is also capable of supplying up to 10mA of output current, making it suitable for a wide range of applications more demanding than the more common low-current requirements.

In terms of its working principle, the LTC2636CDE-LMI10#TRPBF works by converting a digital signal into an analog current output. The digital data is translated into a 16-bit word by using a standard 2’s complement format. The data is then sent to the DAC in MSB-first format. The DAC then sets the output current level according to the digital data. The DAC also provides a power-on-reset circuit, which ensures that the DAC output always starts up in a known state.

To conclude, the LTC2636CDE-LMI10#TRPBF is a low-power 16-bit current-output digital-to-analog converter. It is used in a wide range of applications, including process control and calibration, audio and video circuitry, digital laser printer calibration, and automotive applications. The device works by converting a digital signal into an analog current output, which can then be used for precision and high accuracy control.
