MAX197BEAI Equivalent & Substitute Parts

Part Overview

The MAX197BEAI is a 12-bit Data Acquisition System (DAS) integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It features 8 channels, a 100 kHz sampling rate, and parallel data interface in a 28-SSOP surface mount package. The device operates on single supply voltage and is rated for -40°C to 85°C temperature range.

The MAX197BEAI is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, production continuity, and long-term system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX197BEAI is determined by matching the following critical parameters:

• Number of channels: 8
• Resolution: 12 bits
• Sampling rate: 100 kHz
• Data interface: Parallel
• Voltage supply configuration: Single supply
• Operating temperature range: -40°C to 85°C
• Package: 28-SSOP with identical physical dimensions
• Mounting type: Surface mount

The MAX197BEAI+ qualifies as a direct substitute based on identical specifications across all functional and physical parameters. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX197BEAI+ is the direct functional equivalent of the MAX197BEAI. Both devices share identical electrical and mechanical specifications, including channel count, resolution, sampling rate, data interface, supply configuration, temperature range, and package form factor.

The MAX197BEAI+ is recommended for new designs and production applications due to its active product status and ROHS3 compliance certification. The MAX197BEAI is obsolete and should be replaced in ongoing production to ensure long-term component availability and regulatory compliance.

For existing designs currently using the MAX197BEAI, migration to the MAX197BEAI+ requires no circuit modifications, as the devices are pin-compatible and functionally identical.

Frequently Asked Questions (FAQ)

Q: Can the MAX197BEAI+ directly replace the MAX197BEAI in existing designs?

A: Yes. The MAX197BEAI+ is a direct substitute with identical pinout, electrical specifications, and mechanical package dimensions. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The MAX197BEAI+ is the active production variant with ROHS3 compliance certification. The MAX197BEAI is classified as obsolete. Both devices are functionally equivalent.

Q: Are there any supply voltage differences between the two parts?

A: The MAX197BEAI+ specifies a supply voltage range of 4.75V to 5.25V. The MAX197BEAI does not include explicit voltage specifications in the available data. Both operate on single supply configuration.

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

A: Both the MAX197BEAI and MAX197BEAI+ have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are these devices RoHS compliant?

A: The MAX197BEAI is RoHS non-compliant. The MAX197BEAI+ is ROHS3 compliant. For applications requiring RoHS compliance, the MAX197BEAI+ must be used.
