MAX537BEWE+

Digital To Analog Converters Overview

The MAX537BEWE+ is a quad, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 16-pin SOIC package. It integrates four precision output amplifiers and operates with ±5V supplies. The device features double-buffered digital inputs organized as an input register followed by a DAC register. A 16-bit serial word loads data into each register via an interface compatible with SPI/QSPI or MICROWIRE. Factory calibration ensures a total unadjusted error of ±1 LSB. Key electrical parameters include a resolution of 12 bits, a settling time to ±0.5 LSB of 5 µs, and a typical slew rate of 3 V/µs.

Digital To Analog Converters Procurement Notes

Verify the specific suffix BEWE against the manufacturer's current ordering guide to confirm lead times and availability status. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm that the wide SOIC package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel, high-precision DAC with factory calibration is required. The MAX537 variant specifically supports ±5V supply rails, distinguishing it from the MAX536 which requires asymmetric higher voltages. Verify that the 12-bit resolution and 5 µs settling time meet system performance requirements. Ensure the serial interface timing aligns with the host microcontroller capabilities.

Digital To Analog Converters Part Context

This part belongs to the MAX536/MAX537 family of calibrated, quad, 12-bit voltage-output DACs. The MAX537 series is distinguished by its operation on ±5V supplies, whereas the MAX536 utilizes -5V and +10.8V to +13.2V supplies. Both share identical pinouts and functional architectures but differ in power supply specifications and reference voltage ranges.

Digital To Analog Converters Replacement Considerations

The MAX536BEWE+ is a direct functional substitute within the same package, provided the system can accommodate the MAX536's requirement for asymmetric supplies (-5V and +10.8V to +13.2V) instead of the MAX537's ±5V configuration.
