MAX5700AUB+T

Digital To Analog Converters Overview

The MAX5700AUB+T is a dual-channel, low-power digital-to-analog converter (DAC) with 8-bit resolution. It features buffered voltage outputs and an internal reference selectable to 2.048V, 2.500V, or 4.096V. The device operates on a wide supply voltage range of 2.7V to 5.5V with extremely low power consumption of 1.5mW. A precision external reference input allows rail-to-rail operation and presents a 100kΩ typical load. The DAC utilizes a 50MHz 3-wire SPI/QSPI/MICROWIRE/DSP-compatible serial interface. On power-up, the outputs reset to zero for safety. The part is available in a 10-pin µMAX package and specified over a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual high-accuracy DAC channels with independent mode settings
• Internal output buffers enabling rail-to-rail operation with external references
• Software-selectable internal voltage references at 2.048V, 2.500V, or 4.096V
• Asynchronous clear logic input for immediate zero-scale output initialization

Digital To Analog Converters Applications

• Programmable voltage and current sources
• Gain and offset adjustment circuits
• Automatic tuning and optical control systems
• Power amplifier control and biasing networks
• Process control and servo loops

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm accuracy grade and temperature specifications. Confirm the 'UB' designation matches the required 10-pin µMAX package type. Ensure the '+T' indicates tape-and-reel packaging if applicable. Cross-reference the manufacturer's latest datasheet for any potential obsolescence notices or lifecycle changes before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a compact dual-channel DAC with integrated buffering is required. The separate VDDIO pin supports 1.8V logic interfaces while maintaining a wider analog supply range. Consider the internal reference options if board space for external components is limited. Verify that the settling time and glitch energy meet the dynamic performance requirements of the target application.

Digital To Analog Converters Part Context

This device belongs to the MAX5700/MAX5701/MAX5702 family of ultra-small, dual-channel DACs. The MAX5700 variant specifically provides 8-bit resolution, distinguishing it from the 10-bit MAX5701 and 12-bit MAX5702 models within the same series. All variants share identical pinouts, interfaces, and general electrical characteristics, differing primarily in resolution and linearity specifications.

Digital To Analog Converters Replacement Considerations

Direct replacements include the MAX5701AUB+T and MAX5702AUB+T from the same family, offering higher resolutions of 10-bit and 12-bit respectively. These parts maintain the same package and interface compatibility.
