Texas Instruments  ADS8588HIPMR

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 perchannel. The device features a complete analog front-end for each channel, including a programmablegain amplifier (PGA) with a high input impedance of 1 MΩ, an input clamp, low-pass filter, and anADC input driver. The device also features a low-drift, precision reference with a buffer to drivethe ADC. A flexible digital interface supporting serial, parallel, and parallel byte communicationenables 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 impedanceallows direct connection with sensors and transformers, thus eliminating the need for externaldriver circuits. The high performance and accuracy, along with zero-latency conversions offered bythis device, also means the ADS8588H meets the strict design requirements formany industrial automation and control applications.
