DESCRIPTION
The ADS1610 is a high-speed, high-precision,
delta-sigma (DS) analog-to-digital converter (ADC)
with 16-bit resolution operating from a 5V analog and
a 3V digital supply. Featuring an advanced
multi-stage analog modulator combined with an
on-chip digital decimation filter, the ADS1610
achieves 86 dBFS signal-to-noise ratio (SNR) in a
5MHz signal bandwidth; while the total harmonic
distortion is -94dB.
The ADS1610 DS 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 brick wall response with a very
flat passband (±0.0002dB of ripple) followed
immediately by a very wide stop band (5MHz to
55MHz). Clock jitter becomes especially critical when
digitizing high frequency, large-amplitude signals.
The ADS1610 significantly reduces clock jitter
sensitivity by an effective averaging of clock jitter as
a result of oversampling the input signal.
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.
