AD7664
The Normal Mode is the fastest mode (500 kSPS) without any
limitation on the time between conversions. This mode makes the
AD7664 ideal for asynchronous applications such as data
acquisition systems, where both high accuracy and fast sample
rate are required.
The Impulse Mode, the lowest power dissipation mode, allows
power saving between conversions. When operating at 100 SPS,
for example, it typically consumes only 21
W. This feature
makes the AD7664 ideal for battery-powered applications.
Transfer Functions
Using the OB/
2C digital input, the AD7664 offers two output
codings: straight binary and twos complement. The LSB size is
VREF/65536, which is about 38.15
V. The ideal transfer charac-
teristics for the AD7664 are shown in Figure 4 and Table II.
