The ADS8584S device is an 4-channel, integrated data acquisition (DAQ)system based on a simultaneous-sampling, 16-bit successive approximation (SAR) analog-to-digitalconverter (ADC) operating at a maximum of 330 kSPS per channel. The device featuresa complete analog front-end for each channel, including a programmable gain amplifier (PGA) withhigh input impedance of 1 MΩ, input clamp, low-pass filter, and an ADC input driver.The device also features a low-drift, precision reference with a buffer to drive the ADC. Aflexible digital interface supporting serial, parallel, and parallel byte communication enables thedevice to be used with a variety of host controllers.

The ADS8584S can be configured to accept ±10-V or ±5-V true bipolarinputs using a single 5-V supply. The high input impedance allows direct connection with sensorsand transformers, thus eliminating the need for external driver circuits. The high performance andaccuracy, along with zero-latency conversions offered by this device, also make theADS8584S a great choice for many industrial automation and controlapplications.
