SIMULT ANE OUS SAMPLING A/D CONVE RT E RS
T he AD7821’s inherent track-and-hold and well-defined sam-
pling instant makes it useful, in such applications as sonar,
where a number of input channels are required to be sampled
simultaneously. Figure 22 shows a circuit for such an applica-
tion.
Figure 22. Simultaneous Sampling A/D Converters
T he actual sampling instant, which is the instant at which V
IN
is
measured, occurs approximately 50 ns after the falling edge of
WR
or
RD
in the WR-RD or RD modes, respectively, due to in-
ternal logic delays. However, the internal logic delay and, there-
fore, the sampling instant can vary from device to device, but is
typically within
±
5 ns. T his means that a maximum common in-
put sine wave of
±
2.5 V at 32 kHz, applied to any number of
AD7821s in the circuit of Figure 22, will yield a maximum dif-
ference between the converter outputs of typically
±
1/4 LSB.
