MAX5177AEEE

Digital To Analog Converters Overview

The MAX5177AEEE+ is a low-power, serial, 12-bit digital-to-analog converter with a buffered voltage output. It operates from a single +3V supply (2.7V to 3.6V) and features a precision output amplifier with an accessible inverting input for gain configuration. The device draws 260µA during operation and reduces to 1µA in shutdown mode. It includes a glitch-free power-up feature, a programmable reset state, and a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards.

Digital To Analog Converters Feature Summary

• Force/Sense Voltage Output: Accessible inverting amplifier input allows for adjustable gain and remote sensing configurations.
• Glitch-Free Power-Up: Proprietary circuitry limits output glitches to a few millivolts during startup.
• Low-Power Operation: Consumes 260µA active current, reducing to 1µA in shutdown mode.
• Flexible Serial Interface: Compatible with SPI, QSPI, and MICROWIRE protocols via a 3-wire connection.

Digital To Analog Converters Applications

• Digitally Programmable 4–20mA Current Loops
• Industrial Process Controls
• Digital Offset and Gain Adjustment
• Motion Control Systems
• Automatic Test Equipment (ATE)

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A' indicates ±2 LSB Integral Nonlinearity (INL), whereas 'B' denotes ±4 LSB INL. Confirm the package type is 16-pin QSOP. Ensure the design supports the +3V single-supply requirement, as this variant differs from the +5V MAX5175. Check for RoHS compliance markings on the component body.

Digital To Analog Converters Selection Notes

Select the MAX5177AEEE+ when a single +3V supply is available and moderate linearity (±2 LSB INL) is sufficient. Choose the 'B' version if tighter linearity specifications are not required or for cost optimization. Consider the MAX5175 if a +5V supply rail is present. Evaluate the need for the accessible FB pin for custom gain setups versus standard fixed-gain applications.

Digital To Analog Converters Part Context

The MAX5177 is part of the MAX5175/MAX5177 family of low-power, serial, 12-bit DACs. It serves as the lower-voltage counterpart to the MAX5175, which operates at +5V. Both share identical pinouts and functionality but differ in supply voltage ranges. Higher-resolution upgrades like the 14-bit MAX5171/MAX5173 are pin-compatible alternatives within the same series.

Digital To Analog Converters Replacement Considerations

The MAX5175 is a pin-compatible alternative requiring a +5V supply instead of +3V. For higher resolution, the MAX5171 and MAX5173 offer 14-bit performance in the same package. Devices with internal references, such as the MAX5122/MAX5123 or MAX5132/MAX5133, provide similar form factors but lack the external reference input capability.
