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 independent DAC channels within a single 44-pin PLCC package. The device operates from a ±5V supply and provides bipolar output voltages with up to ±4.5V swing without external components. Each channel includes an on-chip precision output amplifier. The architecture utilizes double-buffered input logic with a 13-bit parallel data bus, allowing simultaneous updates via asynchronous load inputs. Key electrical specifications include a typical settling time of 5µs to ±1/2LSB, guaranteed monotonicity to 13 bits, and INL/DNL errors of ±0.5 LSB and ±1 LSB respectively for the B-grade variant.

Digital To Analog Converters Feature Summary

• Integrates eight 13-bit DACs in a single package with buffered voltage outputs
• Features double-buffered digital inputs for simultaneous multi-channel updates
• Provides calibrated linearity and guaranteed monotonic operation across temperature range
• Includes asynchronous clear input to reset all DAC outputs to analog ground

Digital To Analog Converters Applications

• Automatic Test Equipment
• Digital Offset/Gain Adjustment Systems
• Industrial Process Controls
• Avionics Equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'D' indicates die or tape-and-reel configuration if applicable, though standard datasheets list BCQH as PLCC. Confirm RoHS compliance status for the '+' suffix. Ensure the supplier provides the official Analog Devices datasheet for pinout verification against the 44-pin PLCC footprint. Cross-reference the B-grade accuracy specifications with system requirements.

Digital To Analog Converters Selection Notes

Select this component when multiple high-resolution voltage outputs are required in a compact form factor. The parallel interface suits systems with sufficient I/O lines for 13-bit data buses. Consider the ±5V supply requirement and the need for external reference buffering if driving multiple REF_ pins simultaneously. Verify that the 5µs settling time meets the dynamic response needs of the application.

Digital To Analog Converters Part Context

The MAX547 series represents Maxim Integrated's solution for multi-channel precision conversion. The BCQH variant specifically denotes the commercial temperature range (0°C to +70°C) and the 44-pin Plastic Quad Flat Pack (PLCC) housing. This family is designed for applications requiring synchronized analog output adjustments across several channels.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MAX547 variants such as MAX547BEQH+ for extended temperature ranges or MAX547ACMH+ for plastic flat pack packaging. Check pin compatibility and thermal performance differences when substituting between PLCC and FP packages.
