AD7716BSZ

AD7716 is a signal processing block for data acquisition systems. The device consists of four separate A/D converter channels that are implemented using sigma-delta technology. Sigma-delta ADCs include on-chip digital filtering and, thus, the system filtering requirements are eased. Suitable for use in biomedical data acquisition (ECG Machines, EEG Machines), process control, high accuracy instrumentation and seismic systems applications.

• On-chip low-pass digital filter
• Cut-off programmable from 584Hz to 36.5Hz
• Linear phase response, five line serial I/O and Two's complement coding
• Easy interface to DSPs and microcomputers
• Software control of filter cut-off
• ±5V supply and low power operation: 50mW
• 44 lead PQFP package
• Operating temperature range from -40 to 85°C
