MAX5500BGAP+

Digital To Analog Converters Overview

The MAX5500BGAP+ is a low-power, quad, 12-bit voltage-output digital-to-analog converter (DAC) with a serial interface. It integrates four DACs and four precision output amplifiers in a 20-pin SSOP package. The device operates from a single +5V supply and features a 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. Key electrical parameters include a resolution of 12 bits, an integral nonlinearity error of ±2 LSB, and a typical supply current of 0.85 mA during normal operation. The shutdown mode reduces current consumption to 10 µA. The device supports simultaneous or independent control of the DACs and includes features such as power-on reset and software shutdown.

• Supports low-power operation with a dedicated shutdown mode reducing supply current significantly.
• Features a 3-wire serial interface compatible with standard communication protocols.
• Includes hardware shutdown lockout and active-low reset functionality for system reliability.

Digital To Analog Converters Applications

• Industrial process controls
• Automatic test equipment
• Microprocessor-controlled systems

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking the marking on the 20-pin SSOP package against the official datasheet specifications. Ensure the ordering suffix matches the required supply voltage (+5V for MAX5500) and accuracy grade (B grade). Confirm RoHS compliance status if environmental regulations apply to the assembly process.

Digital To Analog Converters Selection Notes

Select the MAX5500BGAP+ when a +5V single-supply operation is required alongside moderate accuracy needs defined by the B-grade INL specification. Consider this part over the A-grade variant if cost efficiency is prioritized over tighter linearity tolerances. Verify that the serial interface timing requirements align with the host microcontroller's capabilities.

Digital To Analog Converters Part Context

The MAX5500BGAP+ belongs to the MAX5500/MAX5501 family of low-power, quad, 12-bit voltage-output DACs. This series is designed for applications requiring multiple analog outputs controlled via a simple serial interface. The B-grade designation indicates specific performance limits regarding integral nonlinearity compared to the higher-precision A-grade version within the same product line.

Digital To Analog Converters Replacement Considerations

Direct replacements include the MAX5500AGAP+ for improved linearity performance while maintaining the same package and pinout. For lower supply voltage applications, the MAX5501BGAP+ serves as a functional equivalent operating at +3V. Ensure any substitute maintains compatibility with the existing serial interface protocol and thermal requirements.
