TI ADS8578SIPM

The ADS8578S device is an 8-channel integrated data acquisition (DAQ) system based on a 14-bit successive approximation register (SAR) analog-to-digital converter (ADC). All input channels are sampled simultaneously to achieve a maximum throughput of 200 kSPS per channel. Each channel of the device has a complete analog front end, which includes a programmable gain amplifier (PGA) with an input impedance of up to 1 MΩ, input clamps, a low-pass filter, and an ADC input driver. In addition, the device also features a buffered, low-drift, high-precision reference voltage for driving the ADC. With its flexible digital interface, the device supports serial, parallel, and parallel byte communications, making it suitable for various host controllers. The ADS8578S operates from a single 5V power supply and can be configured to accept ±10V or ±5V true bipolar inputs. The high input impedance characteristic allows direct connection to sensors and transformers, eliminating the need for external driver circuits. This device can achieve high performance, high precision, and zero-latency conversion, so the ADS8578S is also an ideal choice for industrial automation and control applications.
