MAX5733BUTN+

Digital To Analog Converters Overview

The MAX5733BUTN+T is a 32-channel, 16-bit voltage-output digital-to-analog converter (DAC) from the MAX5732–MAX5735 family. It features a 0 to +10V output range and accepts a 3V external reference input. The device includes an internal offset DAC for output adjustment and a ground-sensing function for remote ground referencing. A 33MHz SPI/QSPI/MICROWIRE/DSP-compatible serial interface controls the converters, which utilize double-buffered inputs to minimize digital noise feedthrough. The part operates over a temperature range of 0°C to +85°C and is housed in a 56-pin, 8mm x 8mm thin QFN package with an exposed paddle.

Digital To Analog Converters Feature Summary

• Integrated internal offset DAC allows all outputs to be offset simultaneously
• Ground-sensing function enables output voltages referenced to a remote ground
• Double-buffered input structure minimizes digital noise feedthrough and supports synchronous or asynchronous updating
• Proprietary deglitch circuits prevent output glitches at power-up without requiring power sequencing

Digital To Analog Converters Applications

• Automatic Test Systems
• Optical Router Controls
• Industrial Process Controls
• Arbitrary Function Generators
• Avionics Equipment

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the presence of the exposed paddle on the bottom of the 56-pin thin QFN package. Ensure the ordering suffix matches the required tape-and-reel packaging format if applicable. Cross-reference the specific lot code with the manufacturer's traceability records to confirm compliance with RoHS directives and material declarations.

Digital To Analog Converters Selection Notes

Select this model when a 0 to +10V output swing is required, distinguishing it from the MAX5732 (0 to +5V), MAX5734 (-2.5V to +7.5V), and MAX5735 (-5V to +5V). Verify that the system requires exactly 32 channels within a single package. Ensure the application can accommodate the necessary analog supply voltage (AVCC) of 10.5V to 11V to support the full-scale output range while maintaining proper headroom.

Digital To Analog Converters Part Context

This component belongs to the MAX5732–MAX5735 series of high-density multi-channel DACs. The 'B' designation indicates a specific accuracy grade with a maximum Integral Nonlinearity (INL) of ±16 LSB, compared to the 'A' grade which offers ±8 LSB. The 'U' denotes the thin QFN package option, while 'T' typically signifies tape-and-reel packaging for automated assembly processes.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same package include the MAX5732BUTN+T, MAX5734BUTN+T, and MAX5735BUTN+T, provided the output voltage range requirements are adjusted accordingly. For higher accuracy needs, the 'A' grade variants (e.g., MAX5733AUTN+T) offer tighter INL specifications.
