MAX5157BCEE

Digital To Analog Converters Overview

The MAX5157BCEE is a low-power, dual, 12-bit voltage-output digital-to-analog converter (DAC) operating from a single +3V supply. It features rail-to-rail output swing and consumes 500µA in normal operation, reducing to 2µA in shutdown mode. The device supports SPI/QSPI and Microwire serial interfaces with double-buffered input registers. Key electrical parameters include a settling time of 18µs, integral nonlinearity of ±1 LSB, and differential nonlinearity of ±1 LSB.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with configurable output amplifiers
• Single-supply operation optimized for +3V applications
• Rail-to-rail output swing capability
• Hardware-shutdown lockout and programmable logic output

Digital To Analog Converters Applications

• Industrial process control systems
• Digitally programmable 4–20mA current loops
• Remote industrial controls and automatic test equipment
• Motion control and digital offset/gain adjustment

Digital To Analog Converters Procurement Notes

Verify the specific suffix BCEE against the manufacturer's official datasheet to confirm the package type and temperature range. Ensure compatibility with existing board layouts for the 16-pin QSOP footprint. Confirm that the +3V supply requirement aligns with the system design, as this variant differs from the +5V MAX5156 series.

Digital To Analog Converters Selection Notes

Select the MAX5157BCEE when a single +3V supply is available, distinguishing it from the MAX5156 which requires +5V. Consider the 16-pin QSOP package for space-constrained designs. Evaluate the 18µs settling time and ±1 LSB INL/DNL specifications against application accuracy requirements. Verify interface compatibility with the host microcontroller's SPI or Microwire protocol.

Digital To Analog Converters Part Context

The MAX5157BCEE belongs to the MAX5156/MAX5157 family of low-power, dual, 12-bit voltage-output DACs. This family is characterized by its R-2R architecture and configurable output stages. The MAX5157 variant specifically targets lower voltage applications compared to the MAX5156, offering similar functionality but optimized for +3V operation.

Digital To Analog Converters Replacement Considerations

The MAX5157AEEE+ is a direct replacement for the MAX5157AEEE. For the MAX5157BCEE, verify if the MAX5157ACEE+ serves as a compatible alternative based on package and performance matching. Cross-reference pinouts and electrical characteristics to ensure functional equivalence.
