MAX5701AUB+

Digital To Analog Converters Overview

The MAX5701AUB+ is a dual-channel, low-power, 10-bit buffered voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features an internal precision reference selectable to 2.048V, 2.500V, or 4.096V, and accepts a wide supply voltage range of 2.7V to 5.5V with power consumption as low as 1.5mW. The device includes a 50MHz 3-wire SPI/QSPI/MICROWIRE/DSP-compatible serial interface, independent mode settings for each DAC channel, and a clear logic input for asynchronous control. Packaged in a 10-pin µMAX format, it operates over a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual high-accuracy DAC channels with integrated output buffers capable of rail-to-rail operation when used with an external reference.
• Software-selectable internal precision voltage references at 2.048V, 2.500V, or 4.096V, alongside support for external reference inputs.
• Ultra-small 10-pin µMAX package designed for space-constrained portable instrumentation and data acquisition systems.

Digital To Analog Converters Applications

• Programmable Voltage and Current Sources
• Gain and Offset Adjustment
• Automatic Tuning and Optical Control
• Power Amplifier Control and Biasing

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm accuracy grade and reference specifications. Confirm package availability as the µMAX variant may have limited stock compared to standard TSSOP options. Check for end-of-life status or alternative package recommendations from the manufacturer before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component for applications requiring two independent 10-bit outputs with minimal board space. Ensure the system supports the required 2.7V to 5.5V analog supply and 1.8V to 5.5V digital I/O supply. Verify that the 50MHz serial interface timing aligns with the host processor's capabilities and that the 10-pin µMAX footprint fits the PCB layout constraints.

Digital To Analog Converters Part Context

This part belongs to the MAX5700/MAX5701/MAX5702 family of ultra-small, dual-channel DACs. While sharing identical pinouts and core functionality, the MAX5701 specifically offers 10-bit resolution, distinguishing it from the 8-bit MAX5700 and the 12-bit MAX5702. All variants share the same low-power architecture and serial interface compatibility.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same package include the MAX5700AUB+ (8-bit) and MAX5702AUB+ (12-bit). For different resolutions, verify register compatibility and settling time differences. Other packages like TDFN are available but require footprint modification.
