ADS8588S (ACTIVE)

16-Bit High-Speed 8-Channel Simultaneous-Sampling ADC With Bipolar Inputs on a Single Supply

16-Bit High-Speed 8-Channel Simultaneous-Sampling ADC With Bipolar Inputs on a Single Supply - ADS8588S
 

Description

The ADS8588S device is an 8-channel, integrated data acquisition (DAQ) system based on a simultaneous-sampling, 16-bit successive approximation (SAR) analog-to-digital converter (ADC) operating at a maximum 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 ADS8588S 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 ADS8588S a great choice for many industrial automation and control applications.
