MAX196AEAI 12-Bit SAR ADC Equivalent & Substitute Parts

Part Overview

The MAX196AEAI is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc./Maxim Integrated. This data acquisition component features 6 single-ended inputs, parallel data interface, and operates from a 5V supply. The device is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX196AEAI is determined by strict equivalence across the following critical parameters:

• Resolution: 12 bits
• Sampling Rate: 100 kSPS
• Number of Channels: 6 single-ended inputs
• Data Interface: Parallel
• Package: 28-SSOP
• Operating Temperature: -40°C to 85°C
• Supply Voltage Compatibility: 5V operation

The MAX196AEAI+ qualifies as a direct substitute based on identical electrical specifications, package form factor, and pinout compatibility. The primary distinction is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The MAX196AEAI+ is the direct functional equivalent for applications currently using the MAX196AEAI. Selection between these parts should be based on the following criteria:

For New Designs: The MAX196AEAI+ is the appropriate choice. This part maintains active product status with Analog Devices Inc./Maxim Integrated and carries ROHS3 compliance certification, meeting modern regulatory requirements for electronic component procurement.

For Legacy System Support: The MAX196AEAI+ provides pin-for-pin and functional compatibility with existing MAX196AEAI implementations. The supply voltage specification of 4.75V to 5.25V encompasses the nominal 5V operation of the original part, ensuring seamless integration into established designs.

Compliance Considerations: The MAX196AEAI+ achieves ROHS3 compliance status, whereas the original MAX196AEAI is non-compliant. This distinction is material for applications subject to regulatory compliance mandates or procurement policies requiring RoHS-compliant components.

Frequently Asked Questions (FAQ)

Q: Can the MAX196AEAI+ directly replace the MAX196AEAI in existing designs?

A: Yes. The MAX196AEAI+ is a direct substitute with identical pinout, package form factor (28-SSOP), and electrical specifications. No circuit modifications are required for substitution.

Q: What is the difference between MAX196AEAI and MAX196AEAI+?

A: The primary differences are product status and regulatory compliance. The MAX196AEAI is obsolete and RoHS non-compliant. The MAX196AEAI+ is an active product with ROHS3 compliance. Electrically and functionally, both parts are equivalent for 12-bit, 100 kSPS, 6-channel data acquisition applications.

Q: Are there supply voltage differences between these parts?

A: The MAX196AEAI operates at 5V nominal supply. The MAX196AEAI+ specifies a supply voltage range of 4.75V to 5.25V, which includes the 5V nominal operation. This wider specification range does not affect compatibility in 5V-supplied systems.

Q: Is the 28-SSOP package identical for both parts?

A: Yes. Both parts use the 28-SSOP package with 0.209" width and 5.30mm pitch. Package dimensions, pinout, and land pattern are identical.

Q: What is the moisture sensitivity level for these parts?

A: Both the MAX196AEAI and MAX196AEAI+ carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage or handling.

Q: Can I use the MAX196AEAI+ in applications requiring RoHS compliance?

A: Yes. The MAX196AEAI+ is ROHS3 compliant and suitable for applications with RoHS compliance requirements. The original MAX196AEAI does not meet RoHS standards.
