AD7607BSTZ - 8-Channel DAS with 18-Bit, Bipolar Input, Simultaneous Sampling ADC

The AD7607BSTZ is a high-performance, 8-channel data acquisition system (DAS) from Analog Devices Inc. that features an 18-bit, bipolar, simultaneous sampling analog-to-digital converter (ADC). This integrated circuit is designed to cater to the demanding requirements of industrial data acquisition where high precision, wide dynamic range, and simultaneous channel sampling are paramount.

With its robust design, the AD7607BSTZ is capable of sampling up to 200 kSPS (kilo-samples per second) per channel simultaneously, which ensures accurate capture of high-speed signals across multiple channels without the phase delay commonly associated with multiplexed ADC systems. This makes it an ideal choice for advanced industrial applications such as process control, power line monitoring, and instrumentation.

The device accepts a ±10 V input signal, providing a wide dynamic range that is suitable for various sensor types and signal ranges. The input signal is conditioned through an internal track-and-hold amplifier that minimizes distortion and preserves signal integrity, ensuring high-quality data acquisition.

Key features of the AD7607BSTZ include:

• Simultaneous sampling of 8 channels
• 18-bit resolution with no missing codes
• 200 kSPS per channel sampling rate
• True bipolar analog input ranges of ±10 V
• Integrated overvoltage protection of up to ±16.5 V
• Software configurable analog input ranges
• Digital error correction for enhanced accuracy
• Flexible parallel and serial interface options
• On-chip buffer memory for data storage
• Temperature range: -40°C to +85°C

The AD7607BSTZ also features an integrated reference with low drift and noise, which enhances the precision of the conversion. The device is packaged in a compact, surface-mount LQFP-64 package, making it suitable for space-constrained applications.

Overall, the AD7607BSTZ from Analog Devices Inc. represents a robust, high-precision solution for complex data acquisition tasks, where simultaneous channel sampling and high data integrity are required. Its comprehensive feature set ensures that it can meet the needs of the most challenging industrial environments.
