The ADS8588H device is an 8-channel, integrated data acquisition
(DAQ) system based on a 16-bit successive approximation (SAR) analog-to-digital converter (ADC).
All input channels are simultaneously sampled to achieve a maximum throughput of 500 kSPS per
channel. The device features a complete analog front-end for each channel, including a programmable
gain amplifier (PGA) with a high input impedance of 1 MΩ, an 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 ADS8588H 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 means the ADS8588H meets the strict design requirements for
many industrial automation and control applications.
