MAX5120AEEE

Digital To Analog Converters Overview

The MAX5120AEEE is a 12-bit, voltage-output digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and features an internal precision bandgap reference of +2.5V, enabling a full-scale output range of +4.095V. The device draws 500µA in normal operation, reducing to 3µA in power-down mode. It includes a buffered output amplifier with adjustable offset and settles to ±0.5LSB within 20µs. The MAX5120AEEE utilizes a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards and is housed in a 16-pin QSOP package.

Digital To Analog Converters Feature Summary

• 12-bit resolution with ±0.5 LSB INL and ±1 LSB DNL accuracy
• Internal +2.5V precision bandgap reference with <10ppm/°C temperature coefficient
• Single +5V supply operation with 500µA typical supply current
• 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols
• Power-down mode reduces current consumption to 3µA

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the component status as the MAX5120 series may be subject to end-of-life notices or obsolescence. Confirm RoHS compliance and lead-free packaging requirements for the specific ordering suffix AEEE. Ensure that the +5V supply voltage and QSOP-16 package dimensions match the target design constraints before procurement.

Digital To Analog Converters Selection Notes

Select the MAX5120AEEE when a single-channel 12-bit DAC with a +5V supply and +4.095V full-scale output is required. Consider the MAX5121 if a +3V supply and +2.0475V output are needed, or upgrade to the MAX5170/MAX5172 for pin-compatible 14-bit performance. Verify that the 20µs settling time and 500µA current consumption meet system power and speed specifications.

Digital To Analog Converters Part Context

The MAX5120AEEE belongs to the MAX5120/MAX5121 family of low-power, serial voltage-output DACs. It shares pin compatibility with the 13-bit MAX5130/MAX5131 and the 14-bit MAX5170/MAX5172 devices, facilitating easy upgrades within the same package footprint. The 'A' grade indicates tighter linearity specifications compared to the 'B' grade variant.

Digital To Analog Converters Replacement Considerations

For direct replacements, verify availability of the MAX5120AEEE+ variant which offers lead-free/RoHS-compliant packaging. Pin-compatible alternatives include the MAX5130/MAX5131 for 13-bit resolution and the MAX5170/MAX5172 for 14-bit resolution, provided the supply voltage and interface timing requirements remain compatible.
