MAX5201ACUB+

Digital To Analog Converters Overview

The MAX5201ACUB+ is a serial input, voltage-output, 16-bit digital-to-analog converter (DAC) from the MAX5200–MAX5203 family. It operates from a +5V single power supply with an internal reference of +2.5V and an internal gain of 2. The device provides monotonic 16-bit output over temperature without adjustments. Key electrical parameters include a resolution of 16 bits, an integral nonlinearity (INL) of ±20 LSB maximum, and a differential nonlinearity (DNL) of ±1 LSB maximum. The DAC output range is typically from 0 to VDD. Supply current is typically 0.8mA, reducing to 1µA in shutdown mode.

Digital To Analog Converters Feature Summary

• Guaranteed 16-bit monotonic performance without external adjustments
• Integrated +2.5V reference with internal gain of 2 for +5V operation
• Hardware reset input (CLR) clears output to zero code
• Low-power shutdown mode reduces supply current to 1µA

Digital To Analog Converters Applications

• Low-cost VCO/VCXO frequency control
• Industrial process control systems
• High-resolution offset adjustment circuits

Digital To Analog Converters Procurement Notes

Verify that the component matches the specific ordering suffix ACUB, which indicates an operating temperature range of 0°C to +70°C. Ensure compatibility with the required +5V single supply voltage. Confirm package type is 10-pin µMAX. Check datasheet specifications for INL and DNL limits relevant to your application accuracy requirements before finalizing procurement.

Digital To Analog Converters Selection Notes

Select the MAX5201ACUB+ when a +5V supply is available and a zero-scale power-on reset is required. Compare against MAX5200ACUB if midscale reset is preferred. Consider MAX5202/MAX5203 variants only if a +3V or +3.3V supply is mandatory. Verify that the 16-bit resolution and ±20 LSB INL meet system precision needs. Ensure the 10-pin µMAX package fits the board layout constraints.

Digital To Analog Converters Part Context

This part belongs to the MAX5200–MAX5203 series of low-cost, voltage-output DACs. The MAX5201 variant specifically features a zero-scale power-on reset, distinguishing it from the MAX5200 which resets to midscale. All devices in this series share similar architecture but differ in supply voltage requirements and reset behavior. The ACUB suffix denotes the commercial temperature grade.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the MAX5201AEUB for extended temperature range (-40°C to +105°C). Other variants like MAX5200ACUB offer identical electrical performance but with a different power-on reset state (midscale instead of zero). No other manufacturers' parts are confirmed as direct replacements in the provided documentation.

Digital To Analog Converters FAQ

What is the default output state upon power-up for the MAX5201ACUB?

Upon power-up, the MAX5201ACUB resets the DAC output to zero scale (code 0000 hex).

How does the hardware reset input (CLR) function?

Pulling the CLR input low clears the DAC output to zero code (0000 hex) for the MAX5201.

What is the typical supply current consumption during normal operation?

The typical supply current consumption is 0.8mA when all digital inputs are at VDD or DGND.
