概述
Description
AD7226KNZ is an Analog Devices analog-to-digital converter (ADC). It’s a multi-channel, multiplexed ADC with a serial interface (SPI-like) designed for data acquisition and instrumentation. The KNZ suffix denotes the packaging/version variant (RoHS-compliant) used for this part.
Typical usage:
- Connect multiple analog inputs to the channel pins; the ADC multiplexes them to a single conversion core.
- Use the SPI-compatible interface to start conversions, clock data out, and read the digital results.
- Operates with an appropriate reference and supply as specified in the datasheet.
Common applications:
- Industrial control, sensor interfaces, test and instrumentation, precision measurement systems.
For exact specifications (number of channels, resolution, sample rate, input ranges, references, and packaging), refer to the AD7226 datasheet and product page.
