MAX5155ACEE+

Digital To Analog Converters Overview

The MAX5155ACEE+ is a low-power, dual, 12-bit voltage-output digital-to-analog converter (DAC) with a serial interface. It operates from a single +3V supply and consumes 500µA in normal mode, reducing to 2µA in shutdown. The device features rail-to-rail output swing, an internal gain of +2V/V, and a 12µs settling time. It supports SPI/QSPI and Microwire interfaces, includes double-buffered registers, and offers programmable shutdown, hardware-shutdown lockout, and active-low clear functionality.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with internal +2V/V gain for maximized dynamic range
• Rail-to-Rail output swing capability on both channels
• Low power consumption with software-programmable shutdown mode
• Compatible with SPI, QSPI, and Microwire serial interfaces

Digital To Analog Converters Applications

• Industrial Process Control
• Remote Industrial Controls
• Digital Offset and Gain Adjustment
• Microprocessor-Controlled Systems
• Motion Control and Automatic Test Equipment (ATE)

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ACEE+' against the manufacturer's current product status, as legacy Maxim Integrated parts may have varying availability or end-of-life statuses. Confirm that the commercial temperature range (0°C to +70°C) aligns with system requirements. Ensure the QSOP-16 package dimensions are compatible with the target PCB footprint. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the design intent.

Digital To Analog Converters Selection Notes

Select the MAX5155ACEE+ when a single +3V supply is available, distinguishing it from the MAX5154 which requires +5V. The internal +2V/V gain allows for full-scale output swings suitable for standard logic levels without external amplification. Consider the double-buffered input structure if simultaneous updates of multiple DAC channels are required. Verify that the 12-bit resolution and 15µs settling time meet the precision and speed requirements of the application.

Digital To Analog Converters Part Context

This component belongs to the MAX5154/MAX5155 family of low-power, serial, voltage-output DACs manufactured by Analog Devices Inc./Maxim Integrated. The family shares identical functional architectures but differs in supply voltage requirements; the MAX5155 variant is optimized for +3V operation. These devices are designed for space-constrained applications requiring precise analog control via simple serial communication protocols.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include the MAX5154ACEE+ for +5V supply applications. For upgraded performance, consider the MAX5158 series which offers 10-bit resolution with similar interface compatibility. Verify that any substitute maintains the QSOP-16 package and serial interface timing specifications to ensure board-level compatibility.
