MAX537AEWE+

Digital To Analog Converters Overview

The MAX537AEWE+ is a quad, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 16-pin Wide SO package. It operates with ±5V supplies and features factory calibration for high accuracy. The device integrates four precision output amplifiers and utilizes a double-buffered input structure consisting of an input register and a DAC register. Data is loaded via a 16-bit serial word compatible with SPI/QSPI or MICROWIRE interfaces. Key electrical parameters include a typical settling time of 5 µs to ±0.5 LSB, a slew rate of 3 V/µs, and a total unadjusted error of ±3.5 LSB across the -40°C to +85°C temperature range.

Digital To Analog Converters Feature Summary

• Four calibrated 12-bit DACs with integrated buffered voltage outputs
• Double-buffered digital inputs allowing independent or simultaneous updates
• Serial interface compatibility with SPI, QSPI, and MICROWIRE protocols
• Hardware LDAC pin for asynchronous simultaneous DAC register loading

Digital To Analog Converters Applications

• Industrial Process Controls
• Automatic Test Equipment
• Digital Offset and Gain Adjustment
• Motion Control Devices
• Remote Industrial Controls

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EWE+' corresponds to the Wide SOIC-16 package and the -40°C to +85°C industrial temperature grade. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering documentation matches the Analog Devices/Maxim Integrated manufacturer specifications for the MAX537 series.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel 12-bit DAC with buffered outputs is required in a space-saving 16-pin package. The MAX537 variant is specifically designed for ±5V supply operation, distinguishing it from the MAX536 which requires asymmetric higher voltage rails. Verify that the serial interface timing requirements align with the host microcontroller's capabilities.

Digital To Analog Converters Part Context

The MAX537AEWE+ belongs to the MAX536/MAX537 family of calibrated, quad, 12-bit voltage-output DACs. This series is characterized by its R-2R ladder architecture and dual reference inputs (REFAB and REFCD), which allow different full-scale output voltage ranges for pairs of DACs. The device is part of Maxim Integrated's portfolio of precision data converters.

Digital To Analog Converters Replacement Considerations

The MAX536AEWE+ serves as a functional substitute within the same package but requires asymmetric power supplies (+10.8V to +13.2V and -5V) rather than the ±5V configuration used by the MAX537.
