MAX970EEE Equivalent & Substitute Parts

Part Overview

The MAX970EEE is a general-purpose comparator IC manufactured by Analog Devices Inc./Maxim Integrated, featuring four independent comparator elements in a 16-QSOP surface-mount package. This device provides open-drain, rail-to-rail output configuration with supply voltage range of 1.6V to 5.5V, making it suitable for low-power analog signal comparison applications.

The MAX970EEE is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications and new designs requiring comparable functionality.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX970EEE is determined by strict equivalence across the following critical parameters:

• Number of comparator elements: 4
• Output configuration: Open-Drain, Rail-to-Rail
• Supply voltage range: 1.6V ~ 5.5V
• Input offset voltage: 10mV @ 5.5V maximum
• Input bias current: 0.05µA @ 5.5V maximum
• Quiescent current: 18µA maximum
• Common-mode rejection ratio: 56.48dB minimum
• Power supply rejection ratio: 80dB minimum
• Propagation delay: 20µs maximum
• Hysteresis: ±1mV
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-SSOP surface-mount
• Base product number: MAX970

Only parts meeting all these specifications are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The MAX970EEE+ is a direct functional equivalent to the MAX970EEE, with identical electrical specifications and package configuration. The primary distinction is product status and regulatory compliance.

The MAX970EEE is obsolete, whereas the MAX970EEE+ maintains active product status with current manufacturing support. The MAX970EEE+ is ROHS3 compliant, meeting current environmental and regulatory requirements, while the MAX970EEE is RoHS non-compliant.

For new designs and applications requiring long-term component availability and regulatory compliance, the MAX970EEE+ is the appropriate selection. For legacy system maintenance where existing stock of MAX970EEE is available and regulatory compliance is not a constraint, the MAX970EEE remains functionally interchangeable.

Frequently Asked Questions (FAQ)

Q: Can MAX970EEE+ replace MAX970EEE in existing designs?

A: Yes. The MAX970EEE+ is electrically and mechanically identical to the MAX970EEE. Both devices feature four comparator elements, identical supply voltage range (1.6V ~ 5.5V), matching input offset voltage (10mV @ 5.5V), and the same 16-SSOP surface-mount package. Pin-for-pin compatibility is maintained.

Q: What is the difference between MAX970EEE and MAX970EEE+?

A: The primary differences are product status and regulatory compliance. The MAX970EEE is obsolete and RoHS non-compliant. The MAX970EEE+ is an active product with ROHS3 compliance. Electrical performance and package specifications are identical.

Q: Are there any package or mounting differences?

A: Both parts use the 16-SSOP surface-mount package with 0.154" width (3.90mm). Mounting type and PCB footprint are identical. The MAX970EEE+ is supplied in tube packaging, while the MAX970EEE packaging specification is not provided.

Q: What parameters determine substitution eligibility?

A: Substitution is based on matching all electrical and mechanical specifications: four comparator elements, open-drain rail-to-rail output, 1.6V ~ 5.5V supply range, 10mV input offset, 0.05µA input bias current, 18µA quiescent current, 56.48dB CMRR, 80dB PSRR, 20µs propagation delay, ±1mV hysteresis, -40°C ~ 85°C operating temperature, and 16-SSOP package configuration.

Q: Is the MAX970EEE+ suitable for new designs?

A: Yes. The MAX970EEE+ is the recommended choice for new designs due to active product status, ROHS3 compliance, and assured long-term availability. It provides identical functionality to the obsolete MAX970EEE with improved regulatory standing.
