Data Acquisition - Analog to Digital Converters (ADC) are essential components in applications that require the conversion of analog signals into a digital format. The number of applications that require ADC’s is vast, ranging from medical device applications, to process control and metrology, to consumer audio/video, and communications systems. One of the most commonly used ADC devices in these applications is THS1230CDWR. h

The THS1230CDWR is a 12-bit, high-performance Analog-to-Digital Converter (ADC) with differentiating outputs and true rms to dc conversion. The device is available in a compact, 5 mm × 5 mm, 32-lead QFN package and is optimized for consumer and industrial applications. The natively differential inputs of the device allow for the use of both single-ended and differential signals with input ranges of 0V to 5V, -2.5V to 2.5V and -5V to 0V. It has two differential outputs, true RMS-to-DC conversion, a differential voltage gain block, and an analog delta-sigma ADC.

The THS1230CDWR is designed to handle a variety of applications that require high resolution conversion from high frequency differential signals with minimal power consumption and high dynamic performance. It is ideal for use in medical systems, portable applications, power control, professional audio/video systems, and other precision signal applications. In medical systems, it can be used to measure signal parameters such as electrocardiogram (ECG) and pulse oximetry (POX) signals.

The THS1230CDWR device is designed to capture differential analog signals over the full signal range in a single conversion cycle. The internal analogue circuitry consists of a differential voltage gain block, a low pass filter, analog delta-sigma modulator and a low-noise track-and-hold capacitor which captures, stores, and holds the signal while ADC is performing a conversion, providing superior dynamic performance with minimal signal distortion. The true RMS-to-DC conversion driver enables accurate and fast signal processing with low distortion.

The output of the THS1230CDWR ADC is a binary data stream, representing the analog signal in digital format. This data is then passed on to subsequent signal processing stages, where decision algorithms and other techniques are used to interpret and analyze the signal.

The THS1230CDWR provides digital control for ease of integration, with programming options for selecting the digital bit depth, channel selection, sample rate, and power saving mode. This makes the device easy to integrate into user applications. Its low power consumption and minimal area requirement also makes it an attractive option in space-constrained designs.

The THS1230CDWR offers high performance, low noise, and low power consumption in a wide range of applications. Its easy implementation and versatile digital control options makes it an ideal choice for designers who need a reliable and accurate ADC without sacrificing power efficiency or performance. In summary, the THS1230CDWR is an ideal choice for applications that require differential channel to DC conversion.
