Overview
The AD7828UQ is a high-speed, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component features an 8-channel input multiplexer, making it a cost-effective and space-saving solution for multichannel ADC systems. It operates from a single 5 V supply and includes a built-in track-and-hold function, allowing it to digitize full-scale signals of up to 10 kHz without the need for an external sample-and-hold circuit. The AD7828UQ is fabricated in an advanced, all ion-implanted, linear compatible CMOS process (LC2MOS), ensuring low power dissipation and high performance.
