MAX547ACMH

Digital To Analog Converters Overview

The MAX547ACMH is an octal, 13-bit voltage-output digital-to-analog converter (DAC) featuring a parallel interface. It integrates eight independent DACs with on-chip precision output amplifiers, operating from a ±5V supply to provide bipolar outputs swinging up to ±4.5V without external components. The device utilizes double-buffered interface logic with a 13-bit parallel data bus and four separate reference inputs, allowing distinct full-scale voltages for each DAC pair. Key electrical specifications include a typical output settling time of 5µs to ±1/2LSB, INL/DNL errors of ±0.5/±1 LSB maximum, and operation within a commercial temperature range of 0°C to +70°C in a 44-pin plastic flat pack package.

Digital To Analog Converters Feature Summary

• Integrates eight 13-bit DACs with buffered voltage outputs in a single package
• Features double-buffered digital inputs for simultaneous multi-channel updates
• Provides asynchronous load inputs to update pairs of DAC latches independently
• Includes power-on reset circuitry that initializes all DAC outputs to analog ground

Digital To Analog Converters Applications

• Automatic Test Equipment
• Digital Offset/Gain Adjustment
• Arbitrary Function Generators
• Industrial Process Controls
• Avionics Equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CMH' confirms the 44-pin plastic flat pack package and the 'A' grade indicates the specified linearity performance. Confirm the operating temperature range matches the 0°C to +70°C requirement for the intended environment. Ensure the parallel interface timing requirements align with the host microprocessor or controller capabilities.

Digital To Analog Converters Selection Notes

Select this component when multiple high-resolution voltage outputs are required in a compact form factor. The dual-latch architecture supports glitch-free updates across all channels. Consider the R-2R ladder architecture and external reference drive requirements if precise full-scale accuracy is critical for the application design.

Digital To Analog Converters Part Context

The MAX547 series comprises octal 13-bit DACs available in various grades and packages. The ACMH variant specifically denotes the commercial temperature range and plastic flat pack housing. Other variants like the BEMH offer extended temperature ranges or different packaging options while maintaining identical functional specifications.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MAX547 variants such as MAX547BCMH or MAX547BEMH, which share the same pinout and functionality but differ in temperature range or package type.
