MAX5156BEEE+

Digital To Analog Converters Overview

The MAX5156BCEE+ is a low-power, dual, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It operates on a single +5V supply and features rail-to-rail output swing with a typical quiescent current of 500µA in normal operation and 2µA in shutdown mode. The device utilizes an R-2R architecture and includes double-buffered input registers for independent or simultaneous updates. It supports SPI/QSPI and Microwire serial interfaces, offers programmable logic outputs, and provides hardware-shutdown lockout capabilities within a space-saving 16-pin QSOP package.

Digital To Analog Converters Feature Summary

• Dual 12-bit DACs with configurable output amplifier gain via accessible inverting inputs
• Rail-to-Rail output swing capability for maximum dynamic range
• Low power consumption with software-programmable shutdown mode reducing current to 2µA
• Double-buffered input registers allowing independent or simultaneous DAC register updates

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix BCEE+ corresponds to the commercial temperature range (0°C to +70°C) and QSOP-16 packaging as defined in the official datasheet. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure that the ordering documentation explicitly references the MAX5156 series to distinguish it from the similar MAX5157 which operates at +3V. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Digital To Analog Converters Selection Notes

Select the MAX5156BCEE+ when a single +5V supply is available and a commercial temperature range is sufficient. Choose this part over the MAX5157 if the application requires higher supply voltage tolerance. Consider the external reference requirement, as this device does not include an internal reference. Evaluate the need for daisy-chaining capabilities provided by the DOUT pin if multiple units are required in the design.

Digital To Analog Converters Part Context

This component belongs to the MAX5156/MAX5157 family of low-power, dual, 12-bit voltage-output DACs. The MAX5156 variant is specifically designed for +5V operation, whereas the MAX5157 is optimized for +3V supplies. Both share identical pinouts and functional architectures but differ in supply voltage specifications and operating temperature grades. The B suffix typically denotes accuracy grades within the commercial temperature range.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes within the same family include the MAX5156ACEE+, MAX5156BCPE, and MAX5156ACPE. These alternatives offer the same functionality but may differ in integral nonlinearity accuracy or package type (DIP vs. QSOP). Verify that any replacement maintains compatibility with the existing serial interface timing and supply voltage constraints.
