complementary format directly connects to DSPs
such as TI
’s TMS320 family, FPGAs, or ASICs. A
dedicated synchronization pin enables simultaneous
sampling with multiple ADS1601s in multi-channel
systems. Power dissipation is set by an external
resistor that allows a reduction in dissipation when
operating at slower speeds. All of the ADS1601
features are controlled by dedicated I/O pins, which
simplify operation by eliminating the need for on-chip
registers.
The

specified
from
