MAX547BCQH-D

Digital To Analog Converters Overview

The MAX547BCQH-D is an octal, 13-bit voltage-output digital-to-analog converter (DAC) featuring a parallel interface. It integrates eight DACs with on-chip precision output amplifiers in a 44-pin PLCC package. The device operates from a ±5V supply, enabling bipolar output voltages with up to ±4.5V swing without external components. It utilizes four separate reference inputs, each connected to two DACs, allowing different full-scale output voltages for every DAC pair. The architecture employs double-buffered interface logic with a 13-bit parallel data bus and asynchronous load inputs.

Digital To Analog Converters Feature Summary

• Integrates eight 13-bit DACs with calibrated linearity and guaranteed monotonicity
• Features buffered voltage outputs capable of swinging to ±4.5V
• Includes asynchronous load inputs to update pairs of DAC latches simultaneously
• Provides an asynchronous clear input to reset 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 'D' against official documentation, as standard listings typically indicate 'MAX547BCQH'. Confirm the temperature range matches the 'C' designation (0°C to +70°C). Ensure the package type corresponds to the 44-pin PLCC format. Validate that the component is sourced from authorized distributors to guarantee authenticity and traceability.

Digital To Analog Converters Selection Notes

Select this component when multiple independent voltage outputs are required in a single package. The dual-reference architecture allows for flexible gain and offset configurations per channel pair. Ensure the system supports a ±5V supply and has a 13-bit parallel data bus available. Consider the 5µs settling time for dynamic applications requiring fast response.

Digital To Analog Converters Part Context

The MAX547 series provides high-density analog conversion solutions. The 'B' grade indicates tighter linearity specifications compared to the 'A' grade. The 'Q' denotes the plastic leaded chip carrier package. This part belongs to a family of octal DACs designed for systems needing multiple synchronized analog outputs with minimal external circuitry.

Digital To Analog Converters Replacement Considerations

Direct substitutes include MAX547ACQH and MAX547BEQH. These variants share identical pinouts and functionality but differ in accuracy grades and operating temperature ranges. Verify compatibility with existing board layouts and thermal requirements before substitution.
