MAX186ACPP Equivalent & Substitute Parts

Part Overview

The MAX186ACPP is a 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications. It features a Successive Approximation Register (SAR) architecture with configurable input channels (4 or 8), supporting both differential and single-ended inputs. The device operates with dual supply voltages (±5V) and communicates via SPI interface.

The MAX186ACPP is classified as an obsolete product. Finding equivalent or substitute parts is necessary for system redesign, long-term production support, or when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX186ACPP is determined by the following critical parameters:

• Resolution: 12 bits (exact match required)
• Sampling Rate: 133 kSPS (exact match required)
• Data Interface: SPI (exact match required)
• Architecture: SAR (exact match required)
• Package / Case: 20-DIP (exact match required)
• Mounting Type: Through Hole (exact match required)
• Input Channels: 4 or 8 channels (compatible range)
• Input Type: Differential or Single Ended (compatible range)
• Supply Voltage: ±5V or 5V (compatible range)
• Operating Temperature: 0°C ~ 70°C (exact match required)

The MAX186ACPP+ qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering improved product status and compliance certifications.

Engineering Selection Recommendations

The MAX186ACPP+ is a direct functional equivalent to the MAX186ACPP. Key advantages of the substitute include:

• Active Product Status: The MAX186ACPP+ is actively manufactured and supported, ensuring long-term availability and supply chain stability compared to the obsolete MAX186ACPP.
• RoHS3 Compliance: The MAX186ACPP+ meets ROHS3 standards, addressing regulatory requirements for new designs and manufacturing environments that enforce RoHS compliance.
• Identical Electrical Performance: Both devices share identical resolution (12 bits), sampling rate (133 kSPS), operating temperature range (0°C ~ 70°C), and core architecture (SAR).
• Pin-Compatible Packaging: Both devices use the 20-DIP package with identical pinout, enabling direct board-level substitution without layout modifications.
• Enhanced Interface Support: The MAX186ACPP+ supports additional serial protocols (MICROWIRE™, QSPI™, Serial) in addition to SPI, providing greater flexibility for system integration.

Selection of the MAX186ACPP+ is recommended for new designs and production continuity where RoHS compliance and active product support are required.

Frequently Asked Questions (FAQ)

Q: Can the MAX186ACPP+ directly replace the MAX186ACPP in existing designs?

A: Yes. Both devices share identical pin configurations, package dimensions (20-DIP), and core electrical specifications (12-bit resolution, 133 kSPS sampling rate, SPI interface, ±5V supply). Direct board-level substitution is possible without circuit modifications.

Q: What is the primary difference between MAX186ACPP and MAX186ACPP+?

A: The MAX186ACPP+ is an active product with ROHS3 compliance, while the MAX186ACPP is obsolete and RoHS non-compliant. The MAX186ACPP+ also supports additional serial protocols (MICROWIRE™, QSPI™, Serial) alongside SPI.

Q: Are there any supply voltage differences between these devices?

A: The MAX186ACPP supports both ±5V and 5V supply configurations. The MAX186ACPP+ operates with ±5V supply. Verify your circuit design uses ±5V supply voltage for compatibility.

Q: Does the MAX186ACPP+ support the same number of input channels?

A: The MAX186ACPP supports 4 or 8 configurable input channels. The MAX186ACPP+ provides 8 channels. If your application requires only 4 channels, the MAX186ACPP+ remains compatible, as it can be configured to use a subset of available channels.

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

A: Both the MAX186ACPP and MAX186ACPP+ have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Are both devices REACH compliant?

A: Yes. Both the MAX186ACPP and MAX186ACPP+ are REACH Unaffected, meaning they are not subject to REACH regulatory restrictions.
