The ADS8578S device is an 8-channel, integrated data
acquisition (DAQ) system based on a 14-bit successive approximation (SAR) analog-to-digital
converter (ADC). All input channels are simultaneously sampled to achieve a maximum throughput of
200 kSPS per channel. The device features a complete analog front-end 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 ADS8578S 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 transformers, thus eliminating the need for external driver circuits. The high
performance and accuracy, along with zero-latency conversions offered by this device, also make the
ADS8578S a great choice for many industrial automation and control
applications.
