Simultaneously Digitize Eight High-Voltage Arbitrary Swing Signals

June 02, 2016 //By Luc Desimpel

Many common monitoring and control applications require multiple analog input signals to be simultaneously sampled and digitized, preserving time-domain correlation and frequency-domain phase relationships between the signals in the digital domain. The LTC2348-18 is designed specifically for these applications. The device simultaneously samples eight channels of high-voltage input signals and digitizes them using a high-performance 18-bit successive approximation register (SAR) analog-to-digital converter (ADC). It offers superb linearity, noise, DC precision, common-mode rejection ratio, and active crosstalk while converting all channels at 200ksps per channel throughput.
