MAX537ACWE+

Digital To Analog Converters Overview

The MAX537ACWE+ is a quad, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 16-pin Wide SO package. It integrates four precision output amplifiers and operates with ±5V supplies. The device features factory calibration for offset, gain, and linearity, achieving an integral nonlinearity (INL) of ±0.5 LSB. It utilizes a double-buffered input structure with a 16-bit serial word loaded via SPI/QSPI or MICROWIRE interfaces. Key electrical parameters include a typical settling time of 5 µs to ±0.5 LSB, a reference input range of 0V to (VDD - 2.2V), and a positive supply range of 4.5V to 5.5V.

Digital To Analog Converters Procurement Notes

Verify the specific suffix ACWE+ against the manufacturer's current ordering guide to confirm lead time and availability status. Ensure the component meets RoHS compliance requirements for the intended deployment environment. Cross-reference the datasheet revision date with the supplier's documentation to validate parameter accuracy before integration into production designs.

Digital To Analog Converters Selection Notes

Select the MAX537ACWE+ when a quad-channel configuration with ±5V single-supply operation is required. The 'A' grade ensures tighter INL specifications compared to the 'B' grade. Verify that the system load impedance remains above 5kΩ to maintain specified settling times and performance metrics. Confirm compatibility with the host microcontroller's serial clock speeds and logic voltage levels.

Digital To Analog Converters Part Context

This component belongs to the MAX536/MAX537 family of calibrated, quad, 12-bit voltage-output DACs. While the MAX536 variant requires asymmetric supplies (-5V and +10.8V to +13.2V), the MAX537 is optimized for symmetric ±5V operation. Both share identical pinouts and serial interface protocols, differing primarily in power supply requirements and internal amplifier slew rates.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same series include the MAX537BCWE+, which offers a wider operating temperature range but looser INL specifications (±1 LSB). Other variants such as MAX537AEWE+ provide extended temperature ranges with tighter error margins. Ensure any replacement maintains the 16-pin Wide SO package and compatible serial interface timing.
