Description
AD7664ASTZ is an Analog Devices precision analog-to-digital converter (ADC). It’s used to convert analog signals into digital data for instrumentation, data acquisition, and control systems. The ASTZ suffix indicates a specific packaged variant with a defined pinout and form factor. The device emphasizes high-resolution, low-noise performance and typically uses a serial digital interface (SPI-compatible) for easy connection to microcontrollers, DSPs, or FPGAs. It supports flexible input configurations and may include options such as an on-chip reference and selectable input ranges, depending on the exact variant. Common applications include process control, sensor interfacing, and lab instrumentation where accurate, compact conversion is required. For exact specifications—resolution, sampling rate, input range, reference options, power, and timing—consult the AD7664ASTZ datasheet and related resources.
