Data Acquisition - Digital to Analog Converters (DAC) is an important technology used in embedded system to convert digital signal into analog signal, so it can be utilized by analog system. TLV5639CPW is one of the most commonly used digital to analog converters with high performance. This article will discuss the application fields and working principles of the TLV5639CPW to introduce the readers its functions and capabilities.
The TLV5639CPW mostly applies in extended industrial working temperature environment (-40°C to 85°C). It converts 9-bit digital signals into 4-20mA current signals within typical accuracy of ± 0.1% or better using the R-2R ladder technique. This kind of DAC is designed to be integrated in industrial control system for signal compensation, calibration and engine room alarmer etc. The expansion ability makes it also suitable for high definition sound reinforce system. The transfer function of the TLV5639CPW DAC is customizable, it be able to connect to all kinds of most available input signal ranging from 4-20mA to -10V to 10V and it support some special ones as well. All of these make the TLV5639CPW DAC a preferred choice for many industrial control system.
The Working principle behind the TLV5639CPW is relatively simple. It has two set of precision R-2R voltage dividers connected to the digital inputs which generate proportional voltage ranges as the digital inputs change. It also contains two op-amps which are used to reject the noise and transfer the digital input signals. And the four precision resistors convert the analog voltage values into corresponding 4-20mA current output. The four outputs from TLV5639CPW have an internal circuit which avoids current deviation produced by the load of the output transmission line. The TLV5639CPW DAC also features an internal trimming circuit that allows for the fine adjustment of the output current. This makes the output current to maintain very good accuracy.
TLV5639CPW is a very powerful digital to analog converter with 9-bit accuracy and wide working temperature range which is suitable for industrial extended-temperature applications and provides customized transfer function as required. It is a great choice for many industrial control system, making it a preferred choice when comes to data acquisition technology.
