Data acquisition is the process of measuring physical or electrical variables then converting the data into digital form. An Analog-to-Digital Converter (ADC) is a device used to perform this task of converting analog signals into digital representations. The specific ADC device ADS5517IRGZT from Texas Instruments is a Single-Channel High Speed, 12-Bit Analog-to-Digital Converter (ADC) designed for data acquisition applications such as implantable medical devices, medical instrumentation, patient monitors, data acquisition systems, industrial process control and control applications. This device offers high speed performance and accurate conversions with low power consumption.

The ADS5517IRGZT ADC consists of a 12-bit one-channel converter and a 1-channel serializer. It operates from a single supply of 3.3V and achieves a conversion rate of up to 1MSPS. The input signal range of the ADC spans between 1.175V and 2.9V. The device includes several features such as an integrated reference voltage and an asynchronous SPI serial interface. It also includes a sleep mode and single cycle conversion with wake-up mode. This allows the device to be operated in a low power state until a new conversion is needed.

The ADS5517IRGZT ADC operates by first amplifying and filtering the input signal until it is within a reasonable range. This is done by an analog amplifier, low pass filter and anti-aliasing filter. The amplified signal is then passed to the comparator. A series of flips-flops are used to compare the input voltage to a sequence of voltages set by a Waveform Generator. The sequence from the waveform generator is determined by a clock that cycles at the same rate of the input signal. After the comparison is complete the waveform generator initiates a conversion of the output voltage from the comparator into a digital form based on the accumulation from the waveform generator.

The output of the ADS5517IRGZT ADC is made up of two components: a digital result and a clock. The digital result is a 12-bit word representing the analog input amplified ranged between 0 and 4095, where 4095 indicates the maximum input ranges value. The clock is a 14-bit counter that is updated continually during the conversion process. This clock keeps track of the conversion time and is used to generate the serialized data. The serialized data is then outputted and ready for decoding.

The ADS5517IRGZT ADC is a high-performance device providing accurate data acquisition applications. Its low power consumption, high sampling rate and wide input range makes it a viable choice for various applications. It is suitable for use in medical devices, patient monitors, industrial process control and data acquisition systems. The device’s high performance and low power consumption make it an attractive choice for today’s energy conscious applications.
