Overview
The AD7829BRU-1 is a high-speed, 8-channel, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component is designed for high-throughput applications, offering a maximum conversion rate of 2 million samples per second (MSPS). It is microprocessor-compatible and features an on-chip track-and-hold amplifier, a 420 ns conversion time, and a high-speed parallel interface. The ADC operates from a single supply voltage of either 3 V ± 10% or 5 V ± 10% and includes an on-chip 2.5 V reference with a 2% tolerance.
