manufactured on an advanced CMOS process. The

Consequently,
– THD: –103dB at fIN = 100kHz, –6dBFS
signal-to-noise ratio (SNR) is particularly improved.
Total harmonic distortion (THD) is
–103dB, and the

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
high
performing,
easy-to-use
ADS1601
is
especially
suitable
for
demanding
measurement
applications in sonar, vibration analysis, and data
acquisition. The ADS1601 is offered in a small, 7mm

package
and
is
specified
from
–40°C to +85°C.
