Analog Devices AD7829-1 ADC Datasheet
The AD7829-1 is a high‑speed 8‑channel, microprocessor‑compatible 8‑bit analog‑to‑digital converter. It features a 420 ns conversion time, on‑chip 2.5 V reference, track‑and‑hold amplifier, and a flexible parallel interface that supports stand‑alone operation via an EOC pulse. The device operates from a single 3 V ± 10 % or 5 V ± 10 % supply and includes an automatic power‑down function on the CONVST pin.
Typical applications include data‑acquisition systems, DSP front ends, disk drives, and mobile communication subsampling. The parallel interface allows easy mapping into microprocessor address space, and the part can be interfaced to a variety of microcontrollers such as 8051, PIC16C6x/7x, and ADSP‑21xx families.

Questions answered in these manuals
What is the conversion time of the AD7829-1?
The maximum conversion time is 420 ns.
How does the AD7829-1 achieve automatic power‑down?
After a conversion, the CONVST pin is sampled; if it is low, the ADC powers down automatically.
What is the conversion time of the AD7829-1?
The conversion time is 420 ns maximum.
How many analog input channels does the AD7829-1 have?
It provides eight single‑ended analog input channels.
