This schematic block features the AD7689ACPZRL7, a 16-bit, 8-channel PulSAR Analog-to-Digital Converter (ADC) from Analog Devices, engineered for multiplexed data acquisition systems. Delivering sampling rates of up to 250 kSPS, it combines high resolution with low power consumption, making it ideal for precision measurement applications.

Using a successive approximation register (SAR) architecture, the AD7689 provides excellent linearity and accuracy. Its integrated serial interface simplifies communication with microcontrollers, DSPs, and FPGAs, reducing design complexity and system cost. Packaged in a 20-lead LFCSP, it offers a compact solution for high-performance data acquisition.

As part of a Quickboards schematic block, the AD7689 comes with a ready-to-use reference design, allowing engineers to quickly prototype and validate multi-channel systems without the need for complex analog front-end design.
