The ADS1610

topology provides key system-level
design advantages with respect to anti-alias filtering
and clock jitter. The design of the user's front-end
anti-alias filter is simplified since the on-chip digital
filter greatly attenuates out-of-band signals. The
ADS1610s filter has a

Output data is supplied over a parallel interface and
easily connects to TMS320 digital signal processors
(DSPs). The power dissipation can be adjusted with
an external resistor, allowing for reduction at lower
operating speeds.
With its outstanding high-speed performance, the
ADS1610 is well-suited for demanding applications in
data acquisition, scientific instruments, test and
measurement equipment, and communications. The
ADS1610 is offered in a TQFP64 package and is
specified from –40°C to 85°C.
