Overview
The ADS8584SIPM, produced by Texas Instruments, is a 16-bit high-speed, 4-channel simultaneous-sampling analog-to-digital converter (ADC) with integrated analog front-end. This device is part of the ADS8584S series and is designed for high-performance data acquisition applications. It operates on a single 5-V supply and can accept ±10-V or ±5-V true bipolar inputs. The ADS8584SIPM features a complete analog front-end for each channel, including a programmable gain amplifier (PGA), input clamp, low-pass filter, and an ADC input driver. It also includes a low-drift, precision reference with a buffer to drive the ADC, ensuring high accuracy and stability across various operating conditions.
