Low resolution and low input voltage analog-to-digital converters (ADCs) are integrated in many of today's field programmable gate arrays (FPGAs) and microcontrollers. However, they fall short on meeting the needs of industrial control and industrial automation applications that require higher resolutions and higher input voltages. The Fresno (MAXREFDES11#) subsystem reference design is a 16-bit …

Three-phase power measurement applications require multiple analog inputs for voltage and current measurements on each line of the three-phase system. A power monitoring system must sample all of the analog inputs simultaneously to accurately calculate the instantaneous power consumption.

In industrial control and industrial automation applications, high-resolution data converters are often required. Although today's field programmable gate arrays (FPGAs) and microcontrollers may integrate analog-to-digital converters (ADCs), in many cases, the resolution is not high enough and isolation is lacking.

This design is for an 18-bit data acquisition block at 1MSPS throughput optimized for the lowest distortion and noise performance. The circuit is realized with an 18-bit successive-approximation-resistor (SAR) analog-to-digital converter (ADC), a fully differential input driver and a high precision reference and reference driver. The design details the process for optimizing the precision front en…
