AD7657BSTZ-REEL Typical application Circuitry

AD7657BSTZ-REEL

Precision data acquisition systems are the target market for the high-performance, dual-channel, 16-bit analog-to-digital converter (ADC) known as the AD7657BSTZ-REEL. It can sample two channels simultaneously, which makes it appropriate for applications that need to acquire multi-channel data at rapid speeds.

Situations of Applications:

There are several uses for the AD7657BSTZ-REEL, such as:

- Medical imaging systems

- Industrial process control

- Instrumentation and measurement systems

- Data acquisition systems

Parameter Features:

- Dual 16-bit ADCs with simultaneous sampling

- Throughput rate: 250 kSPS per channel

- Voltage range of input: ±10 V

- Low power consumption: 90 mW per channel

- Flexible parallel/serial interface

Circuit Design for a Data Acquisition System:

1. Power Supply: Connect a +5V supply to the AVDD and DVDD pins for analog and digital power, respectively. Ground the AGND and DGND pins for analog and digital grounds.

2. Input Signal Conditioning: Connect the AD7657BSTZ-REEL analog input signals to the AIN1 and AIN2 pins. Use appropriate filtering and buffering circuits to condition the signals before they reach the ADC inputs.

3. Reference Voltage: Connect a precision 2.5V reference voltage to the REF IN(+) and REF IN(-) pins to set the ADC's input voltage range.

4. Clock Source: Connect a stable clock source to the CLK IN pin to provide the sampling clock for the ADCs. The AD7657BSTZ-REEL clock frequency determines the sampling rate.

5. Data Output: Configure the interface mode (parallel or serial) using the PAR/SER pin. For parallel mode, connect the DB[15:0] pins to a microcontroller or FPGA for data retrieval. For serial mode, use the DOUTA and DOUTB pins for channel A and B data output, respectively.

6. Control Signals: Utilize the CNVST pin to initiate conversions and the BUSY pin to monitor the ADC's status. Ensure proper timing between the CNVST signal and the clock source for accurate sampling.

Design Considerations:

- Ensure a clean and stable power supply to minimize noise and ensure accurate conversions.

- Properly filter and buffer the input signals to prevent aliasing and signal distortion.

- Select a suitable reference voltage for the desired input range and accuracy.

- Maintain proper timing between the control signals and the clock source to synchronize data acquisition.

- Reduce noise coupling between analog and digital portions by implementing suitable grounding and designing strategies.

These criteria, along with the application's particular needs, can be followed to develop a reliable and accurate data acquisition system that makes use of the AD7657BSTZ-REEL ADC.
