MAX531AEPD

Digital To Analog Converters Overview

The MAX531AEPD is a low-power, voltage-output, serial 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply or dual ±5V supplies and draws only 260µA with its internal reference. The device features an R-2R architecture with a buffered voltage output, guaranteed monotonicity over temperature, and flexible output ranges including unipolar and bipolar configurations. It includes a power-on reset and a serial data output for daisy-chaining. The component is housed in a 14-pin Plastic DIP package and supports SPI, QSPI, and Microwire interfaces.

Digital To Analog Converters Feature Summary

• Cellular telephones

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AEPD' corresponds to the -40°C to +85°C extended temperature range and 14-pin PDIP package as documented in the official datasheet. Confirm RoHS compliance status for the '+' suffix variant. Check current availability through authorized distributors as this component may be subject to limited supply or obsolescence notices.

Digital To Analog Converters Selection Notes

Select the MAX531AEPD when a 12-bit resolution DAC with low power consumption is required for single or dual supply applications. Ensure the design accommodates the 14-pin PDIP footprint. Consider the internal reference stability and noise performance if high precision is needed, or opt for external references if lower noise is critical. Verify interface compatibility with the host microcontroller's SPI or Microwire settings.

Digital To Analog Converters Part Context

The MAX531 is part of the MAX531/MAX538/MAX539 family of low-power, voltage-output, serial 12-bit DACs. While the MAX538 and MAX539 are available in 8-pin packages with fixed gains, the MAX531 offers greater flexibility with configurable gain (+1 or +2) and bipolar operation in a 14-pin package. This family is designed for battery-powered and portable applications requiring minimal power dissipation.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MAX531 variants with different temperature grades or packaging, such as MAX531ACPD or MAX531BCSD. For pin-compatible alternatives with similar specifications, consider the MAX538 or MAX539 if the application does not require the MAX531's specific bipolar or configurable gain features.
