The AD7858ARZ-REEL is a 12-bit, 200 kSPS analog-to-digital converter from Analog Devices featuring a multiplexed 4/8-channel input and SPI interface. Its MUX-S/H-ADC architecture ensures accurate sampling of multiple signals. With both external and internal reference options, this ADC offers flexibility for various applications including industrial automation, medical monitoring, and portable instrumentation. Available in a 24-SOIC package.
- Multi-Channel Flexibility: 4 or 8 multiplexed inputs reduce component count in multi-sensor systems.
- SPI Interface: Simple serial connection to microcontrollers and DSPs, saving I/O pins.
- Dual Reference Options: Internal or external reference provides design flexibility for different accuracy needs.
- Wide Temperature Range: -40°C to +85°C for industrial and automotive applications.
Multi-Channel Data Acquisition
The 8-channel multiplexed input of the AD7858ARZ-REEL allows monitoring multiple sensors in industrial process control, with 12-bit resolution ensuring accurate measurement of each channel.
Portable Instrumentation
The SPI interface and 200 kSPS sampling rate make this ADC suitable for battery-powered data loggers and handheld meters, where low pin count and moderate speed are required.
Medical Patient Monitoring
Multiple channels can be used to acquire ECG, temperature, and pressure signals simultaneously, with the internal reference simplifying the analog front-end design.
Automotive Sensor Arrays
In automotive test systems, the 4 or 8 channel configuration allows digitizing various sensor outputs (temperature, position, pressure) with a single ADC, reducing system cost.
Industrial Automation
The -40°C to +85°C operating range and SPI interface enable integration into PLCs and remote I/O modules for monitoring analog signals in factory environments.
