ADS8588SIPMR

The ADS8588S device is an 8-channel, 16-bit, successive approximation register (SAR) synchronous sampling analog-to-digital converter (ADC) based on an integrated data acquisition (DAQ) system. The maximum sampling frequency per channel is 200 kSPS. Each channel of this device has a complete analog front end, which includes a programmable gain amplifier (PGA) with an input impedance of up to 1 MΩ, input clamping, a low-pass filter, and an ADC input driver. In addition, the device also has a buffered, low-drift, high-precision reference voltage for driving the ADC. With a flexible digital interface, the device supports serial, parallel, and parallel byte communications, making it suitable for various host controllers. The ADS8588S 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 an external driver circuit. This device can achieve high performance, high accuracy, and zero-delay conversion. Therefore, the ADS8588S is also well-suited for industrial automation and control ICs.
