Analog to digital converters, or ADCs, are an important class of integrated circuits that take in an analog input voltage and convert it into a digital output code. Specifically, the IDTADC1212D065F2-DB is an Application Specific Integrated Circuit (ASIC) that is used in applications requiring a low-power, high-resolution, 8-bit ADC. This article will discuss the application field and working of principles of this particular ADC.

Application Field of IDTADC1212D065F2-DB

The IDTADC1212D065F2-DB is an 8-bit, 200kHz, analog-to-digital converter that is suitable for a wide range of applications. It is intended for use in low power, low cost, portable, and other embedded signal processing systems requiring high-performance conversion of analog input signals. Some of its typical applications include temperature sensing, data acquisition, signal analysis, motor control, audio recording, and battery monitoring.

Working Principle of IDTADC1212D065F2-DB

The IDTADC1212D065F2-DB is a high-speed, low-power SAR-based ADC with a typical sampling rate of 200Ksps. It combines an antialias filter, adjustable gain amplifier, sample & hold, and an 8-bit SAR core with a tracking ADC in a single 20-pin package. Its adjustable gain amplifier and antialias filter provide a wide dynamic range and high-performance signal acquisition. The device can operate from a 2.4V to 3.6V DC supply voltage, and is capable of different bandwidths depending on the value of the signal being acquired.

The IDT converter provides a specific conversion cycle time: a conversion is initiated when the device fires the conversion start command, which sets the start of the conversion cycle. During the time of conversion the device samples the input signal, performs the analog to digital conversion, and updates the conversion result in the digital output code, which is resolved at the end of the conversion cycle. The device can be configured to use either software or hardware triggering to begin the conversion cycle. On chip calibration techniques ensure user friendly operation.

Conclusion

The IDTADC1212D065F2-DB is an 8-bit, 200kHz, analog-to-digital converter that is suitable for a wide range of applications. It is intended for use in low power, low cost, portable, and other embedded signal processing systems requiring high-performance conversion of analog input signals. Its adjustable gain amplifier and antialias filter provide a wide dynamic range and high-performance signal acquisition. The combination of a sample & hold and a tracking ADC on the same chip makes for a powerful and precise ADC which is suitable for a variety of applications.
