Instructions:

The ADS8598HIPMR device is an 8-channel integrated data acquisition (DAQ) system based on an 18-bit successive approximation (SAR) analog-to-digital converter (ADC). All input channels are sampled simultaneously to achieve a maximum throughput of 500kSPS per channel.

Each channel of the device has a complete analog front end (AFE) containing a programmable gain amplifier (PGA) with input impedance up to 1MΩ, input clamp, low-pass filter, and ADC input driver. In addition, the device has a low drift, high-precision reference voltage with a buffer for driving the ADC. With a flexible digital interface, the device supports serial, parallel, and parallel byte communication for a variety of host controllers.

The ADS8598H uses a single 5V power supply and can be configured to accept ±10V or ±5V true bipolar input.
