The AD7828UQ is an 8-bit, 8-channel analog-to-digital converter from Analog Devices, designed for multi-channel data acquisition in demanding environments. It features a multiplexed sample-and-hold architecture, allowing it to sequentially sample up to eight analog inputs. The parallel interface enables efficient communication with microprocessors. It requires an external reference for precise voltage scaling. Packaged in a 28-CDIP ceramic package, it operates over the full military temperature range of -55°C to 125°C, making it suitable for aerospace, defense, and industrial applications where multiple signals must be monitored reliably.
- 8-Channel Multiplexing: Reduces component count by integrating eight analog inputs into one ADC.
- Wide Operating Temperature: -55°C to 125°C ensures performance in extreme conditions.
- Rugged Ceramic Package: 28-CDIP provides high mechanical and environmental durability.
- Simple Parallel Interface: Easy to connect to 8-bit or 16-bit microprocessors.
- MUX-S/H Architecture: Ensures accurate sampling of each channel with minimal crosstalk.
Multi-Channel Data Acquisition
The 8-channel input makes the AD7828UQ perfect for monitoring multiple analog signals in a system, such as reading eight different temperature sensors or potentiometers.
Industrial Control Systems
In PLCs and industrial controllers, this ADC can digitize various process variables (pressure, flow, level) from multiple transmitters, simplifying the interface.
Automotive Test Equipment
With a -55°C to 125°C range, it can be used in engine test stands to monitor multiple parameters like throttle position, manifold pressure, and temperature simultaneously.
Medical Patient Monitoring
For vital signs monitors, the 8 channels can acquire ECG, SpO2, and temperature signals, providing a compact solution for multi-parameter monitoring.
Robotics and Motion Control
In robotic arms, the ADC reads joint position sensors and torque sensors across multiple axes, enabling precise control in harsh environments.
Avionics Signal Conditioning
The ceramic DIP package and wide temperature range make it suitable for flight control systems where multiple analog signals need to be digitized reliably.
