Product Details
AD7609BSTZ - 8-Channel 18-Bit Simultaneous Sampling ADC (DAS, LQFP-64)
AD7609BSTZ is a high-performance 18-bit simultaneous sampling analog-to-digital converter from Analog Devices (ADI). It integrates 8 input channels, internal analog front-end, and flexible input range options, making it ideal for data acquisition systems (DAS), power monitoring, and industrial control applications.
This page provides engineering-level product insight for selection and comparison. Always verify final design parameters using the official ADI datasheet.
Overview
AD7609BSTZ integrates 8 simultaneous sampling ADC channels with an internal analog front end, eliminating the need for external signal conditioning components in many designs. Each channel includes input clamp protection, filtering, and a high-precision ADC core.
It supports ±10V and ±5V input ranges and achieves high throughput with low power consumption. The simultaneous sampling architecture ensures accurate phase measurement across channels, which is critical in multi-phase systems such as power grid monitoring and motor control.
Key Advantages
Captures all 8 channels at the same instant for accurate phase and timing analysis.
Reduces external components with built-in clamp protection and filtering.
18-bit resolution enables precise signal measurement in industrial systems.
Supports ±10V and ±5V inputs for a wide range of signal types.
Feature Summary
18-bit SAR ADC architecture.
8 channels simultaneous sampling.
Selectable ±10V / ±5V analog input range.
Up to 200 kSPS per channel.
Package & Footprint
The AD7609BSTZ is available in a 64-lead LQFP package, suitable for high-density data acquisition systems.
- Separate analog and digital ground planes.
- Place decoupling capacitors close to supply pins.
- Optimize signal routing to minimize noise coupling.
Always refer to the official datasheet for exact mechanical dimensions.
Pin Functions
The device includes analog inputs, digital interface, and control pins.
