Analog Devices Inc./Maxim Integrated MAX5426AEUD+

MAX5426AEUD+ combines precision fixed resistors and digitally controlled variable resistors for a traditional three-op-amp instrumentation-amplifier topology. It is a resistor network, not a complete stand-alone amplifier: external op amps determine much of the final signal-chain performance.

The manufacturer lists MAX5426AEUD+ in a 14-pin TSSOP package. The LCDChip package registry normalizes the original 14-TSSOP (0.173-inch, 4.40-mm body width) entry to 14-TSSOP.

Layout checks

• Use the official 14-pin TSSOP land-pattern and pin-one orientation.
• Confirm the package drawing and terminal dimensions for the exact orderable part.
• Place VDD-to-GND and VSS-to-GND bypass capacitors close to the device, as advised in the data sheet.

The registered package illustration is currently unavailable locally and must be supplied and visually verified before publication.

The pin names and assignments below follow the manufacturer's 14-pin TSSOP pin-description table.

Use the manufacturer's top-view drawing when routing the PCB; function names are not a substitute for checking pin-one orientation.

Typical values are at +25 °C where specified. The gain-accuracy figure assumes ideal external op amps; system-level accuracy must include the amplifier and layout errors.

MAX5426BEUD+ and MAX5426CEUD+ are manufacturer-listed B- and C-grade members of the same MAX5426 family and are present as exact models in the LCDChip catalog. They have the same nominal 14-TSSOP family package and gain selections, but the manufacturer specifies looser maximum gain-range accuracy of 0.09% and 0.5%, respectively. Do not substitute either grade where the A-grade 0.025% accuracy budget is required.

The catalog also contains MAX5426AEUD without the plus suffix. Its exact environmental and lead-finish status must be verified against manufacturer ordering documentation; matching the base function and package does not establish an unconditional replacement. Confirm supply range, accuracy, pinout, package drawing, lifecycle, finish and procurement requirements before any swap.

MAX5426 was introduced by Maxim Integrated and is now documented by Analog Devices. The official MAX5426 product page lists MAX5426AEUD+ as an orderable part model and identifies the family as a precision resistor network for programmable instrumentation amplifiers. Its displayed lifecycle requires procurement confirmation before a production commitment.

Check the complete MAX5426AEUD+ marking, packaging, traceability and supplier documentation before receipt. For a lifecycle-sensitive precision part, confirm authorized channel availability, lead finish and handling condition. The package image shown here is a reference illustration only and is presently pending upload; it cannot authenticate an individual device.

Use the latest manufacturer-controlled MAX5426 data sheet and package drawing for design sign-off. Verify the full temperature, supply, logic and gain-error conditions with the selected external op amps. Inventory and prices are procurement data that can change without notice and are intentionally kept outside this technical description. The package illustration and current distributor quote require additional verification before this product can be published.
