MAX982CUA-T Equivalent & Substitute Parts

Part Overview

The MAX982CUA-T is a dual comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This linear IC operates across a supply voltage range of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply), featuring a maximum input offset voltage of 10mV at 5V and 50mV hysteresis. The device is packaged in an 8-TSSOP/8-MSOP surface mount configuration with 0.118" width (3.00mm).

The MAX982CUA-T is classified as obsolete. Locating equivalent or substitute parts is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The substitute identified maintains identical electrical and mechanical specifications while offering active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX982CUA-T is determined by strict equivalence across the following critical parameters:

• Dual comparator architecture with integrated voltage reference
• Identical supply voltage range: 2.5V ~ 11V (single) or ±1.25V ~ 5.5V (dual)
• Matching input offset voltage specification: 10mV @ 5V
• Identical quiescent current: 6µA maximum
• Matching CMRR and PSRR performance: 80dB each
• Identical hysteresis: 50mV
• Operating temperature range: 0°C ~ 70°C
• Package compatibility: 8-TSSOP/8-MSOP surface mount, 0.118" width (3.00mm)
• Base product number: MAX982

The identified substitute maintains 100% electrical and mechanical compatibility with the original part. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MAX982CUA+T is a direct functional equivalent to the MAX982CUA-T. Both parts share identical electrical specifications and package geometry, ensuring pin-for-pin compatibility and circuit-level interchangeability.

The MAX982CUA+T offers the advantage of active product status, providing access to current manufacturing, quality assurance, and supply chain support. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

The primary difference is packaging format: the original part is supplied in tube format, while the substitute is supplied in Tape & Reel (TR) format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX982CUA+T replace MAX982CUA-T in existing designs?

A: Yes. The MAX982CUA+T is electrically and mechanically identical to the MAX982CUA-T. All electrical parameters, pin assignments, and package dimensions are equivalent. Direct substitution is supported without circuit modification.

Q: What is the difference between tube and Tape & Reel packaging?

A: Tube packaging supplies components in a plastic tube suitable for manual handling and small-quantity applications. Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly. Both formats contain identical components with identical specifications.

Q: Why is the MAX982CUA-T classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. The MAX982CUA+T, with active status, represents the current equivalent offering from
