JM38510/12103BJA Application Field and Working Principle

Data Acquisition - Digital to Analog Converters (DAC) are specialized integrated circuits that are designed to convert digital signals to analog voltage. As such, they are commonly used in electronic circuits to convert digital signals from microprocessors into analog format for various signal processing applications.The JM38510/12103BJA is a 8 bit synchronous serial Digital to Analog Converter. It is designed to convert digital data to analog output voltage with high accuracy and high speed. The device has two 8-bit registers (DAC1 and DAC2) that store the data. The output is created by using the data stored in the specific in these two registers.The JM38510/12103BJA has a serial data input and a serial data output. The device has an integrated 8-bit Digital to Analog Converter that can produce an analog output voltage from -10V to +10V. It also has a separate Digital control input that enable the user to change the output voltage by providing differential control.The device has a synchronous serial interface (SPI) that supports both 3-wire and 4-wire serial transmission. The integrated Digital to Analog Converter allows the user to select different gain, offset and DP for the output voltage.The JM38510/12103BJA is suitable for a variety of signal processing applications such as audio/voice applications, audio amplifier/receiver applications and controller applications. It can also be used in communication protocols and multiplex systems.The working of JM38510/12103BJA DAC is based on the differential switching circuit. It has a unidirectional differential switching circuit, which means a current switch-pair is made up of P-type and N- type transistors. The DAC switches the current pair ON and OFF to generate the analog output voltage.The output voltage is generated by selectively controlling the ON and OFF time of the transistor pair. When the ON time is longer than OFF time, then the output voltage is positive. Similarly, when the OFF time is longer than ON time, then the output voltage is negative.The output of the DAC can be programmed by means of a digital control input. This allows the user to adjust the output voltage by providing differential control.The power consumption of the JM38510/12103BJA is very low, which makes it ideal for battery operated devices. The device also has a low stand-by current of 25µA and a forward operating voltage of 3.3V.Overall, the JM38510/12103BJA is a versatile 8-bit Digital to Analog Converters that provides accurate analog outputs in high speed applications. It is suitable for a wide range of signal processing applications, including audio/voice applications, audio amplifier/receiver applications and controller applications. The device also has low power consumption and a programmable output voltage, which makes it suitable for many different applications.
