MAX5122BEEE

Overview

The MAX5122BEEE is a low-power, 12-bit voltage-output digital-to-analog converter (DAC) featuring an internal precision bandgap reference and output amplifier. It operates on a single +5V/+3V supply with a maximum analog and digital supply voltage of 5V and a minimum of 3V. The device provides a buffered voltage output through a serial interface compatible with 3-Wire, Microwire, QSPI, and SPI protocols. Key performance metrics include a settling time of 20µs, a DNL of ±1 LSB, and an INL of ±0.5 LSB. It consumes 500µA of operating current and dissipates up to 667mW. The component is housed in a 16-lead QSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a precision bandgap reference and output amplifier for stable voltage conversion
• Supports flexible serial communication via 3-Wire, Microwire, QSPI, and SPI interfaces
• Delivers high accuracy with ±0.5 LSB integral nonlinearity and ±1 LSB differential nonlinearity

Applications

• Force/Sense DAC applications requiring precise control
• Low-power industrial instrumentation systems
• Battery-operated measurement devices

Procurement Notes

Verify the specific suffix and manufacturer designation carefully, as availability varies significantly between distributors. Some listings indicate limited stock or obsolete status for certain variants like the MAX5122BEEE+T. Confirm RoHS compliance and package type (QSOP-16) against your bill of materials before ordering, as supply chain constraints may affect lead times for this Analog Devices/Maxim Integrated component.

Selection Notes

Select the MAX5122BEEE when a single-channel, 12-bit resolution is required with integrated buffering and reference capabilities. It is suitable for designs needing low power consumption (500µA) and operation from a single 3V to 5V supply. Ensure the system supports the required serial interface protocols and that the 16-QSOP package fits the PCB layout constraints.

Part Context

This component belongs to the MAX5122/MAX5123 family of low-power, 12-bit voltage-output DACs manufactured by Analog Devices Inc./Maxim Integrated. These devices are designed to provide accurate digital-to-analog conversion with minimal external component requirements due to the integrated reference and amplifier. The MAX5122 variant specifically offers a single channel with force/sense capabilities.

Replacement Considerations

The MAX5123BEEE+ is a documented direct substitute within the same product family, offering similar 12-bit resolution and QSOP packaging. Verify pin compatibility and electrical specifications against the datasheet before substitution.
