Analog Devices Introduces Industry’s First 24-Bit Sigma Delta A/D Converter with True Rail-to-Rail Analog and Reference Input Buffers On-chip
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.
