ADS8588H에 대한 설명
The ADS8588H 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.
