MAX190BENG Equivalent & Substitute Parts

Part Overview

The MAX190BENG is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for single-channel data acquisition applications. It features a Successive Approximation Register (SAR) architecture with a 76 kSPS sampling rate, internal reference, and dual supply voltages (5V analog and digital). The device is packaged in a 24-pin DIP format suitable for through-hole mounting.

The MAX190BENG is classified as obsolete. Finding equivalent or substitute parts is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The MAX190BENG+ provides a direct functional replacement with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

The MAX190BENG+ qualifies as a direct substitute based on the following criteria:

• Identical resolution: 12 bits
• Identical sampling rate: 76 kSPS
• Identical number of inputs: 1
• Identical input type: Pseudo-Differential
• Identical data interfaces: SPI and Parallel
• Identical architecture: SAR
• Identical reference type: Internal
• Identical supply voltages: 5V analog and digital
• Identical operating temperature range: -40°C to 85°C
• Identical package and pinout: 24-DIP (0.300", 7.62mm)
• Identical mounting type: Through Hole

The substitution is based on functional equivalence across all electrical and mechanical parameters. The primary difference is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX190BENG+ is the appropriate substitute for the obsolete MAX190BENG. Both devices are electrically and mechanically identical across all functional parameters. The MAX190BENG+ offers the following advantages:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Tube packaging provides standard handling and storage conditions

Selection of the MAX190BENG+ is recommended for new designs, system upgrades, and legacy system maintenance where the MAX190BENG is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the MAX190BENG+ be used as a direct replacement for the MAX190BENG in existing designs?

A: Yes. The MAX190BENG+ is functionally identical to the MAX190BENG across all electrical and mechanical parameters, including resolution, sampling rate, input configuration, data interfaces, supply voltages, operating temperature range, and package pinout. No design modifications are required.

Q: What is the difference between the MAX190BENG and MAX190BENG+?

A: The primary differences are product status and compliance certification. The MAX190BENG is obsolete and RoHS non-compliant, while the MAX190BENG+ is an active product with ROHS3 compliance. Functionally, both devices are identical.

Q: Are there any package differences between these parts?

A: Both devices use the same 24-DIP (0.300", 7.62mm) package with through-hole mounting. The MAX190BENG+ is supplied in tube packaging, which is standard for active products.

Q: What parameters determine substitution eligibility for the MAX190 series?

A: Substitution is based on matching resolution (12 bits), sampling rate (76 kSPS), number of inputs (1), input type (Pseudo-Differential), data interfaces (SPI and Parallel), architecture (SAR), reference type (Internal), supply voltages (5V analog and digital), operating temperature range (-40°C to 85°C), and package type (24-DIP).

Q: Is the MAX190BENG+ suitable for new product designs?

A: Yes. The MAX190BENG+ is an active product with current compliance certifications, making it appropriate for new designs requiring 12-bit, single-channel SAR ADC functionality with 76 kSPS sampling rate and 5V operation.
