MAX983ESA+ Equivalent & Substitute Parts

Part Overview

The MAX983ESA+ is a dual comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This 8-SOIC surface mount device operates across supply voltages of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply), with a maximum input offset voltage of 10mV at 5V and 50mV hysteresis. The device is Active status and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance, package compatibility, and operating specifications align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAX983ESA+ are qualified based on the following criteria:

Electrical Equivalence: Supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual), input offset voltage (10mV @ 5V), quiescent current (≤6µA), CMRR/PSRR (80dB minimum), hysteresis (50mV), and operating temperature range (-40°C ~ 85°C or 0°C ~ 70°C).

Package Compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package.

Regulatory Compliance: ROHS3 compliant, MSL 1 rating, REACH unaffected status.

Output Type Consideration: The MAX983ESA+ features standard output. Substitute parts with open-drain output (LTC1842 and LTC1843 series) are functionally equivalent but require external pull-up resistors for standard logic-level outputs.

Packaging Format: Tube and Tape & Reel (TR) packaging options are interchangeable for component selection; packaging choice depends on assembly process requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Output Type): The MAX983ESA+ is the primary reference part. No alternative with identical standard output type is listed in the substitute set.

Functional Substitutes (Open-Drain Output): The LTC1842 and LTC1843 series are functionally equivalent comparators with voltage reference. Both series maintain identical electrical specifications (supply voltage, input offset, quiescent current, CMRR/PSRR, hysteresis) and package format. The open-drain output requires external pull-up resistor implementation for standard logic-level operation.

Temperature Range Selection:

• LTC1842IS8 and LTC1843IS8 variants: -40°C ~ 85°C (matches MAX983ESA+ range)
• LTC1842CS8 and LTC1843CS8 variants: 0°C ~ 70°C (restricted range)

Select industrial temperature range (-40°C ~ 85°C) variants when application requires full temperature coverage.

Packaging Format Selection:

• Tube packaging (#PBF suffix): Standard for manual assembly and small-volume procurement
• Tape & Reel packaging (#TRPBF suffix): Optimized for automated pick-and-place assembly

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can LTC1842 and LTC1843 series parts directly replace MAX983ESA+ without circuit modification?

A: LTC1842 and LTC1843 series are functionally equivalent in electrical performance and package format. However, the open-drain output requires external pull-up resistor to achieve standard logic-level outputs. Circuit design must accommodate this output configuration difference.

Q: What is the difference between LTC1842 and LTC1843 series?

A: Both series are dual comparators with voltage reference, identical electrical specifications, and 8-SOIC package. The primary distinction is base product number designation (LTC1842 vs. LTC1843). Both are qualified substitutes for MAX983ESA+.

Q: Are temperature-restricted variants (0°C ~ 70°C) suitable for industrial applications?

A: LTC1842CS8 and LTC1843CS8 variants operate within 0°C ~ 70°C range. Applications requiring -40°C ~ 85°C operation must use LTC1842IS8 or LTC1843IS8 variants to match MAX983ESA+ temperature specification.

Q: Does packaging format (Tube vs. Tape & Reel) affect electrical performance?

A: Packaging format does not affect electrical performance. Selection depends on assembly process: Tube packaging for manual or low-volume assembly; Tape & Reel for automated high-volume production.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (LTC1842 and LTC1843 series) maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status consistent with MAX983ESA+.

Q: What is the propagation delay specification for substitute parts?

A: LTC1842 and LTC1843 series specify 12µs maximum propagation delay. This parameter is not specified for MAX983ESA+ in the provided data.
