Reference Design for 18-Bit Precision Data Acquisition System
Manufactured By:Maxim Integrated
Part Number:MAXREFDES74
The MAXREFDES74# reference design performs high-speed, 18-bit, precision data acquisition based on Maxim’s leading-edge, high-accuracy, low-power data converters.
The MAXREFDES74# design works as a building block for a high-speed, low-power, high-accuracy data acquisition and control system for industrial process control and automation, and high-speed protection systems for power distribution and automation. By changing the ADC and DAC to pin-compatible 16-bit devices such as the MAX11166 and the MAX5316, a 16-bit data acquisition system can also be tested.
