FAQs

What is AD7609BSTZ?

The AD7609BSTZ is a simultaneous sampling, 18-bit analog-to-digital converter (ADC) designed by Analog Devices. It is well-suited for applications requiring high-speed, high-accuracy data acquisition, such as industrial automation, power quality monitoring, and instrumentation systems.

How Does AD7609BSTZ Work?

The AD7609BSTZ operates by simultaneously sampling multiple analog input channels and converting them into digital data with high resolution and precision. It utilizes a successive approximation register (SAR) architecture to achieve fast conversion rates and low latency. The ADC features an on-chip reference and flexible digital interface for seamless integration into various systems.

How Many Pins does AD7609BSTZ have and What are the Functions of the Pinout Configuration?

The AD7609BSTZ is housed in a 64-lead LQFP (Low-Profile Quad Flat Package) package. The pinout configuration includes:

  • AIN1 to AIN8: Analog input channels for simultaneous sampling.
  • REFIN: Analog reference input.
  • DGND, AGND: Digital and analog ground pins, respectively.
  • DB[17:0], CONVST, BUSY, RD, RESET, RANGE, and others: Digital control and data interface pins.

What are the Pros and Cons of AD7609BSTZ?

Pros:
