MAX5123AEEE+T

Digital To Analog Converters Overview

The MAX5123AEEE+T is a low-power, 12-bit voltage-output digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It operates on a single +3V supply with an internal +1.25V precision bandgap reference. The device features a buffered output amplifier capable of driving 5kΩ loads or 4–20mA circuits. It draws 500µA during operation and reduces to 3µA in power-down mode. The DAC utilizes a double-buffered input register and supports SPI, QSPI, and MICROWIRE serial interfaces. It is housed in a 16-pin QSOP package and specified for the -40°C to +85°C industrial temperature range.

Digital To Analog Converters Procurement Notes

Verify the component status as the MAX5123MEEE+ variant is listed as obsolete in some distributor records. Confirm availability through authorized Analog Devices channels. Ensure the ordering suffix matches the required accuracy grade (+A vs +B). Check for RoHS compliance documentation corresponding to the specific manufacturing batch.

Digital To Analog Converters Selection Notes

Select the MAX5123AEEE+T for applications requiring a +3V supply and a +1.25V internal reference. Choose this part over the MAX5122 if lower voltage operation is necessary. Consider the MAX5132 or MAX5171 series for pin-compatible upgrades to 13-bit or 14-bit resolutions respectively. Ensure the load impedance is greater than 1kΩ to maintain specified performance levels.

Digital To Analog Converters Part Context

This component belongs to the MAX5122/MAX5123 family of force/sense DACs. It shares the same 16-pin QSOP footprint and pinout as the MAX5122, which operates at +5V. The family is designed for cascading multiple devices via its daisy-chain compatible serial interface. It serves as a bridge between microprocessor control signals and analog actuator requirements in embedded systems.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives include the MAX5132 (13-bit) and MAX5171 (14-bit) for higher resolution needs. For direct replacement within the same resolution class, verify the MAX5123B variant if different accuracy grades are acceptable. No other direct cross-model substitutes are documented in the provided datasheet.
