MAX992EUA Equivalent & Substitute Parts

Part Overview

The MAX992EUA is a dual-channel general-purpose comparator manufactured by Analog Devices Inc./Maxim Integrated, featuring CMOS open-drain output with rail-to-rail capability and TTL compatibility. The device operates across a supply voltage range of 2.5V to 5.5V (single supply) or ±1.25V to ±2.75V (dual supply), housed in an 8-TSSOP/8-MSOP surface-mount package.

The MAX992EUA is classified as obsolete, with 15,350 units currently in stock. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for ongoing design support, production continuity, and long-term component availability. Substitute parts must maintain electrical compatibility across key parameters including supply voltage range, input offset voltage, propagation delay, and package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX992EUA are selected based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Compatibility Parameters:

• Package form factor: 8-TSSOP/8-MSOP (0.118", 3.00mm Width) surface mount
• Output type: Open-drain configuration
• Number of elements: Dual-channel (2 comparators)
• Supply voltage overlap: Minimum 2.5V to 5.5V single supply capability
• Input offset voltage: Maximum 5mV or lower
• Operating temperature range: Minimum -40°C to 85°C coverage

Substitution Categories:

Category 1: Direct Packaging Equivalent (Same Supplier Device Package) MAX992EUA+ (Analog Devices Inc./Maxim Integrated) - Active product status with identical electrical specifications and 8-uMAX/uSOP packaging. Differs only in packaging format (Tube vs. standard).

Category 2: Functional Equivalents with Extended Supply Voltage Range LMC6772AIMM/NOPB (Texas Instruments) - Open-drain comparator with extended supply voltage range (2.7V ~ 15V), lower quiescent current (20µA), and improved input bias current (0.04pA). Operates within the MAX992EUA supply envelope with enhanced performance margins.

Category 3: Dual-Function Amplifier/Comparator Devices TLV2302IDGK and TLV2302IDGKR (Texas Instruments) - Amplifier/comparator hybrid devices with open-drain output, compatible supply voltage range, and identical package footprint. Product status: Last Time Buy.

Category 4: Enhanced General-Purpose Comparators TLV3402CDGK, TLV3402CDGKR, TLV3402IDGK, TLV3402IDGKR (Texas Instruments) - General-purpose CMOS open-drain comparators with extended supply voltage range (2.5V ~ 16V or 2.7V ~ 16V), superior CMRR/PSRR performance (88dB/105dB), and identical package footprint. Operating temperature ranges vary by variant.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: MAX992EUA+ The MAX992EUA+ is the direct active-status equivalent, maintaining identical electrical specifications and operating parameters. This part is manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and differs only in packaging format (Tube). Selection of MAX992EUA+ eliminates all electrical compatibility concerns and is the preferred choice for direct replacement in existing designs.

Secondary Recommendation: TLV3402IDGKR The TLV3402IDGKR (Texas Instruments) is the only substitute part with Active product status among the Texas Instruments alternatives. It provides extended supply voltage range (2.7V ~ 16V), superior CMRR/PSRR performance (88dB/105dB vs. 80dB/80dB), and extended operating temperature range (-40°C ~ 125°C). The trade-off is significantly increased propagation delay (300µs vs. 210ns), which is acceptable only in non-time-critical applications. All regulatory certifications (ROHS3, MSL 1) match the original part.

Alternative for Extended Supply Voltage: LMC6772AIMM/NOPB The LMC6772AIMM/NOPB (Texas Instruments) offers the lowest quiescent current (20µA vs. 96µA) and superior input bias current performance (0.04pA vs. 1pA). Extended supply voltage range (2.7V ~ 15V) provides additional design margin. Propagation delay (10µs) is slower than MAX992EUA but faster than TLV3402 variants. Suitable for power-sensitive applications within the overlapping supply voltage envelope.

Caution: TLV3402CDGK and TLV3402CDGKR These variants have restricted operating temperature range (0°C ~ 70°C), which does not meet the MAX992EUA specification (-40°C ~ 85°C). Selection is appropriate only for applications with narrower temperature requirements.

Caution: TLV2302 Variants TLV2302IDGK and TLV2302IDGKR are classified as Last Time Buy with incomplete electrical specifications in the provided data. These parts are dual-function amplifier/comparator devices and should be selected only when amplifier functionality is required alongside comparator operation.

Frequently Asked Questions (FAQ)

Q: Can MAX992EUA+ be used as a direct drop-in replacement for MAX992EUA? A: Yes. MAX992EUA+ is manufactured by the same supplier with identical electrical specifications, supply voltage range, input offset voltage, propagation delay, and operating temperature range. The only difference is packaging format (Tube vs. standard). PCB layout and circuit design require no modification.

Q: What is the primary limitation of TLV3402 variants as substitutes? A: Propagation delay increases from 210ns (MAX992EUA) to 300µs (TLV3402 series), representing a 1,428× increase. This makes TLV3402 unsuitable for high-speed comparator applications. Applications with response time requirements below 300µs must use MAX992EUA+ or LMC6772AIMM/NOPB.

Q: Why do TLV3402CDGK and TLV3402CDGKR have restricted operating temperature range? A: These variants are specified for 0°C ~ 70°C operation, which does not overlap the full MAX992EUA range (-40°C ~ 85°C). Selection is limited to applications operating within 0°C ~ 70°C. Extended-temperature variants (TLV3402IDGK and TLV3402IDGKR) support -40°C ~ 125°C.

Q: Is LMC6772AIMM/NOPB compatible with 2.5V single-supply operation? A: LMC6772AIMM/NOPB is specified for 2.7V minimum supply voltage, which exceeds the MAX992EUA minimum of 2.5V. Applications requiring 2.5V operation must use MAX992EUA+ or TLV3402 variants with 2.5V minimum specification.

Q: What is the package compatibility across all substitute parts? A: All substitute parts use 8-TSSOP/8-MSOP (0.118", 3.00mm Width) surface-mount packaging, identical to MAX992EUA. PCB footprints are mechanically compatible without layout modification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating, matching MAX992EUA environmental compliance.

Q: Which substitute part offers the best power efficiency? A: LMC6772AIMM/NOPB provides the lowest quiescent current at 20µA, compared to 96µA for MAX992EUA and 950nA for TLV3402 variants. For ultra-low-power applications, TLV3402 series offers superior quiescent current performance at the cost of increased propagation delay.

Q: Can TLV2302 variants replace MAX992EUA in comparator-only applications? A: TLV2302 variants are dual-function amplifier/comparator devices with incomplete electrical specifications in available documentation. While functionally capable of comparator operation, they introduce unnecessary amplifier circuitry. MAX992EUA+ or TLV3402 variants are preferred for dedicated comparator applications.
