The MAX196ACWI is a highly integrated analog-to-digital converter (ADC) designed for use in a variety of industrial, consumer and medical applications. The integrated ADC and other digitally enabled features make the MAX196ACWI a highly versatile device, able to operate in a variety of operating conditions. This application note provides an overview of the MAX196ACWI, its applications, and its working principle.

Application Field

The MAX196ACWI is capable of addressing a wide range of application fields. It features two integrated, simultaneous sampling 10-bit successive approximation (SAR) analog-to-digital converters, each with up to 150ksamples/s conversion rate. This makes the MAX196ACWI ideal for signal conditioning in a variety of applications, including industrial, consumer, and medical applications where signal accuracy and SNR (signal-to-noise ratio) are critical.

The ADC also features a Dynamic Range Adjustment (DRA) feature, which can be used to extend its dynamic range to 15-bits. Combined with its low-noise capability, the MAX196ACWI provides a range of applications including low-noise, precision measurements in medical imaging, industrial process control, and data logging.

The MAX196ACWI also features a range of digitally enabled features designed to enable easy integration into a variety of systems. These features include a flexible bus interface, coupled with support for multiple power saving modes to ensure low power operation even when the ADC is not in active use. In addition, the integrated programmable gain amplifier (PGA) and reference buffer provide ample gain and headroom for signal conditioning in high-precision, low-noise industrial and medical applications.

Working Principle

The MAX196ACWI is a successive approximation converter (SAR) which works by successively sampling the analog input and comparing it to an internal reference voltage. Each time the reference voltage is adjusted, the sampled input is compared to the updated reference voltage until the two are equal. The number of cycles of comparison required for the reference voltage to reach the analog input is equivalent to the input voltage’s value.

To ensure the highest resolution possible from the device and to ensure compatibility with external devices, the MAX196ACWI supports both single-ended and differential input sampling. The device also support up to four differential analog inputs and up to 1500k samples/s conversion rate.

The MAX196ACWI also features an integrated programmable gain amplifier (PGA), which allows the user to quickly adjust the analog input to an optimal level, without the need for any external components. In addition, the device also has an integrated reference buffer, which allows for quick and easy changes to the reference voltage, without the need for external components.

Finally, the MAX196ACWI includes an on-board temperature sensor, enabling accurate and timely temperature sensing, which can be used to supplement the ADC’s precision, ensuring accuracy in applications where temperature monitoring is required.

Conclusion

The MAX196ACWI is a highly versatile analog-to-digital converter, capable of addressing a wide range of applications fields from industrial to medical applications. The device integrates two high-speed 10-bit SAR ADC accompanied with limitless features such as DRA to 15-bits, dual mode input, PGA, reference buffer and on-board temperature sensor for reliable measurements. All these functions have enabled the device to become one of the most widely adopted ADC among a range of applications.
