General Description

The AD7821 is a high speed, 8-bit, sampling, analog-to-digital converter that offers improved performance over the popular AD7820.

It offers a conversion time of 660 ns (versus 1.36 µs for the AD7820) and 100 kHz signal bandwidth (versus 6.4 kHz).

The sampling instant is better defined and occurs on the falling edge of WR or RD.
