The ADS8588H is a 16-bit data acquisition (DAQ) system with 8-channel, single-ended analog inputs. Each analog input channel consists of an input clamp protection circuit, a programmable gain amplifier (PGA), a third-order, low-pass filter (LPF), and a track-and-hold circuit that facilitates simultaneous sampling of the signals on all input channels. The sampled signal is digitized using a 16-bit analog-to-digital converter (ADC), based on the successive approximation register (SAR) architecture. This overall system can achieve a maximum throughput of 500 kSPS for each channel. The device features a 2.5-V internal reference with a fast-settling buffer, a programmable digital averaging filter to improve noise performance, and high-speed serial and parallel interfaces for communication with a wide variety of digital hosts.

The device operates from a single 5-V analog supply and can accommodate true bipolar input signals of ±10 V or ±5 V. The input clamp protection circuitry can tolerate voltages up to ±15 V . The device offers a constant 1-MΩ resistive input impedance irrespective of the sampling frequency or the selected input range. The integration of multiple, simultaneously sampling precision ADC inputs and analog front-end circuits with high input impedance operating from a single 5-V supply offers a simplified end solution without requiring external high-voltage bipolar supplies and complicated driver circuits.
