Analog Devices Introduces Industry's First 24-Bit Sigma Delta A/D Converter with True Railto-Rail Analog and Reference Input Buffers On-chip
Ultralow noise, A/D converter with a fast and flexible output data rate for high precision instrumentation and process control
applications
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 distributedcontrol-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.
