MAX180ACQH+D

ADCs/DACs - Special Purpose Overview

The MAX180ACQH+D is a high-speed, 8-channel, 12-bit data acquisition system manufactured by Analog Devices Inc./Maxim Integrated. It integrates an 8-channel multiplexer, a high-bandwidth track-and-hold amplifier, and a successive approximation analog-to-digital converter (ADC) with a serial interface. The device operates from a single +5V supply or dual ±5V supplies, supporting software-configurable unipolar/bipolar and single-ended/differential analog inputs. Key electrical specifications include a maximum sampling rate of 100ksps, a conversion time of 10µs, and a full-scale input range of ±2.5V. The component is housed in a 44-lead PLCC package.

• Features a 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols without external logic.
• Operates on a single +5V supply or dual ±5V supplies to accommodate various system power architectures.

ADCs/DACs - Special Purpose Applications

• Industrial process control systems requiring multi-channel signal monitoring.
• Data acquisition modules for automated test equipment.
• Battery-powered instrumentation utilizing single-supply operation.
• Portable handheld devices where low power consumption is critical.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'Q' against official documentation to confirm temperature grade and package type. Confirm RoHS compliance status associated with the '+' designation. Ensure the 44-lead PLCC footprint matches the target PCB design. Validate that the serial interface timing meets the host microcontroller requirements.

ADCs/DACs - Special Purpose Selection Notes

Select this component when eight channels of 12-bit resolution are required at speeds up to 100ksps. Consider the MAX180ACQH+D over parallel interfaces if board space is limited due to the serial connection. Evaluate the ±2.5V input range against sensor output levels to determine if external scaling is necessary. Compare power consumption metrics against other members of the MAX180 family for battery life optimization.

ADCs/DACs - Special Purpose Part Context

This part belongs to the MAX180 series of low-power, high-speed data acquisition systems. The series typically includes variants such as the MAX180AEQH and MAX180CEPL, which share similar core functionalities but differ in package types like PDIP or PLCC. The AC suffix generally denotes commercial temperature range performance within the Maxim Integrated portfolio.

ADCs/DACs - Special Purpose Replacement Considerations

Direct substitutes within the same family include the MAX180AEQH and MAX180CEAP+. Verify pin compatibility and thermal specifications before substitution. Cross-reference datasheets to ensure the replacement variant supports the required serial protocol and input voltage ranges.
