The LTC2637IMS-HMI8#PBF is a highly integrated Digital to Analog Converter (DAC) used numerously in various markets. It is capable of providing a 16-bit resolution, whereby very accurate signals can be attained in various voltage ranges. It includes an integrated power-on reset, on-chip reference and an I2C compatible serial interface.

The LTC2637IMS-HMI8#PBF is mainly used in motor control, power electronics and signal-processing applications. In motor control applications, the DAC can be used to regulate the speed and direction of the motor, by using feedback signals to control the motor’s position. A similar approach is taken for power electronics applications, where accurate voltage signals are needed for controlling the system’s load.

In signal-processing applications, the DAC can be used to generate an accurate replica of the analog signal needed to be applied to the system. This DAC, equipped with a 16-bit resolution and wide operating voltage range, is more than capable of providing the accurate signals needed in such applications.

Working principle

The LTC2637IMS-HMI8#PBF is based upon the architecture of the voltage output DAC (V-Out DAC). This type of integrated circuit is used in various fields of engineering, where a static and accurate output voltage is needed. The circuit works in the following manner. First, the DAC receives an input voltage, as reference voltage. This reference voltage is then used to calculate a digital equivalent, which is subsequently given to the output. The output voltage is then generated from a specific multiplication ratio, with the help of an internal voltage reference.

A great advantage of the LTC2637IMS-HMI8#PBF is that it performs very differently in terms of settling time, analog noise, and Temperature Coefficient of Offset (TCO). The LTC2637IMS-HMI8#PBF has a very wide output range, from 0.2V to 2.5V, and has exceptional performance in terms of settling time (20µs max). It also has an offset error of ±1 LSB and a gain error of ±1 LSB. Additionally, the TCO of the DAC is a very significant 0.02%/°C, enabling the use of this device in a wide range of applications.

Conclusion

The 16-bit DAC, LTC2637IMS-HMI8#PBF, is a great example of Digital to Analog conversion. Its various features, such as its wide output range, good settling time and low TC offset, makes it suitable for a wide range of applications, from motor control to signal-processing. The device uses a very simple architecture that relies upon the reference voltage to calculate the output voltage, and therefore makes it very easy to program.
