Wednesday, December 05, 2012:
Analog Devices, Inc. (ADI), a global leader in high-performance signal processing technology and the data converter market share leader*, today introduced a multiplexed 24-bit sigma-delta A/D converter that doubles the throughput rate of alternative sigma-delta converters while dissipating less power. Designed for process automation and instrumentation systems where data channel density is increasing and channels must be monitored faster, ADI’s new AD7176-2 A/D converter achieves a 50-kSPS (thousand samples per second) multi-channel scan rate.
|
|
In an automated, high-precision production line, the performance of the AD7176-2 allows for faster manufacturing while achieving the precision, low-input bandwidth signal measurements that are inherently associated with the sigma-delta architecture. Measured on a single channel, the AD7176-2 delivers as many as 17.2 noise-free bits at 250 kSPS and 22 noise-free bits at 5 SPS.

The AD7176-2 A/D converter includes high-precision, on-chip peripherals, including a 2.5-V, ±2.5-ppm/°C reference and ±2.5% internal oscillator that reduce board space and lower bill of materials costs while maintaining high performance. The new converter features flexible on-chip digital filters, which optimize settling, resolution and line frequency rejection. The new converter also can be configured on a per-channel basis allowing for different filter and output data rates as well as per-channel offset and gain error correction.
AD7176-2 24-bit Sigma-Delta A/D Converter Key Features:
· 5-SPS to 250-kSPS output rate for fast and flexible updates
· 17.2 noise free bits at 250 kSPS for more accurate measurements
· Up to 90-dB 50-Hz and 60-Hz line frequency rejection using enhanced 50-Hz and 60-Hz rejection filters
· 7.8-mA total current consumption
