The ADS8598H device is an 8-channel, integrated data acquisition (DAQ) system based on a 18-bit successiveapproximation (SAR) analog-to-digital converter (ADC). All input channels are simultaneouslysampled to achieve a maximum throughput of 500 kSPSper channel. The device features a complete analog front-end (AFE) for each channel, including aprogrammable gain amplifier (PGA) with high input impedance of 1 MΩ, input clamp,low-pass filter, and an ADC input driver. The device also features a low-drift, precision referencewith a buffer to drive the ADC. A flexible digital interface supporting serial, parallel, andparallel byte communication enables the device to be used with a variety of hostcontrollers.

The ADS8598H 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 makes theADS8598H a great choice for many industrial automation and controlapplications.
