NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. (NASDAQ: ADI) introduced today the industry’s first sigma-delta
converter with a fully integrated true rail-to-rail
input buffer providing system designers with the industry’s leading
noise performance at up to 250 kSPS throughput.
The AD7175-2 A/D
sigma-delta converter delivers 24 noise-free bits at 20 SPS and 17.2
noise-free bits at 250 kSPS providing designers a wider dynamic range,
which enables smaller signal deviations to be measured as required
within analytical laboratory instrumentation systems. With twice the
throughput for the same power consumption versus competing solutions,
the AD7175-2 enables faster, more responsive measurement systems
providing a 50-kSPS/channel scan rate with 20 micro second settling
time. This combination makes it an ideal choice for use in
programmable-logic controller and distributed-control-system input
modules.
The integrated, low-noise, true rail-to-rail input buffer enables quick
and easy sensor interfacing, reduces design and layout complexity,
simplifies analog drive circuitry and reduces PCB area. The AD717x
family, with a wide range of pin and software compatible devices, allows
consolidation and standardization across system platforms.
