All input channels are simultaneously sampled to achieve a maximum throughput of 200 kSPS per channel.
The device features a complete analog front-end (AFE) for each channel, including a programmable 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 reference with a buffer to drive the ADC.
A flexible digital interface supporting serial, parallel, and parallel byte communication enables the device to be used with a variety of host controllers.
The ADS8598S can be configured to accept ±10-V or ±5-V true bipolar inputs using a single 5-V supply.
The high input impedance allows direct connection with sensors and transformer...
