MAX5157AEEE

Digital To Analog Converters Overview

The MAX5157AEEE is a discontinued dual, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates on a single +3V supply with a typical quiescent current of 500µA and 2µA in shutdown mode. The device features rail-to-rail output swing, a 3-wire SPI/Microwire compatible serial interface, and independent reference inputs for each channel. It includes double-buffered registers, power-on reset, and an active-low clear input.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with configurable output amplifiers allowing force-and-sense remote sensing
• Low-power operation with software-programmable shutdown reducing current to 2µA
• Double-buffered input registers enabling independent or simultaneous updates
• Serial data output pin supports daisy-chaining multiple devices

Digital To Analog Converters Applications

• Industrial process control systems
• Digitally programmable 4–20mA current loops
• Motion control applications
• Automatic test equipment
• Remote industrial controls

Digital To Analog Converters Procurement Notes

Verify component status as the MAX5157AEEE is listed as obsolete and no longer manufactured. Confirm availability through authorized distributors or surplus markets. Ensure replacement components meet original electrical specifications and pin compatibility requirements before integration into existing designs.

Digital To Analog Converters Selection Notes

Select the MAX5156 variant if a +5V supply is required instead of the +3V supply used by the MAX5157. Both devices share identical pinouts and functional characteristics. Consider the R-2R architecture and settling time when designing for high-speed signal generation. Verify that the load impedance does not degrade performance below specified limits.

Digital To Analog Converters Part Context

This component belongs to the MAX5156/MAX5157 family of low-power, dual, 12-bit voltage-output DACs. These devices are designed for applications requiring precise analog control with minimal power consumption. The family offers configurable outputs and robust serial interfaces suitable for embedded microcontroller systems.

Digital To Analog Converters Replacement Considerations

No direct public substitutes are confirmed in the provided documentation. Designers should evaluate newer Maxim Integrated or Analog Devices DAC families with similar resolution, supply voltage, and package dimensions. Cross-reference pinouts and serial interface protocols to ensure compatibility.
