MAX1202AEPP+ Equivalent & Substitute Parts

Part Overview

The MAX1202AEPP+ is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring moderate sampling rates and flexible input configurations. This SAR (Successive Approximation Register) architecture device supports both differential and single-ended inputs with configurable channel selection via an integrated multiplexer and sample-and-hold circuit.

The MAX1202AEPP+ is classified as an active product with full RoHS3 compliance and REACH unaffected status, making it suitable for current production designs. Alternative equivalent parts may be required due to supply constraints, regional availability, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1202AEPP+ is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Sampling Rate: 133 kSPS minimum performance
• Input Configuration: Support for 4 or 8 channels with differential and single-ended input modes
• Data Interface: SPI serial communication protocol
• Architecture: SAR-based conversion methodology
• Reference Options: Both external and internal reference support
• Supply Voltage Compatibility: Analog supply (±5V, 5V) and digital supply (2.7V ~ 5.25V)
• Operating Temperature: -40°C ~ 85°C range
• Package Compatibility: 20-DIP form factor with through-hole mounting
• Compliance: RoHS3 compliance and REACH unaffected status

Only parts meeting all these parameters qualify as direct equivalents or substitutes for the MAX1202AEPP+.

Parameter Comparison

Engineering Selection Recommendations

The MAX1202AEPP+ is an active product with full regulatory compliance (RoHS3 compliant, REACH unaffected). Component selection should prioritize parts with identical electrical specifications, package form factor, and compliance certifications to ensure direct functional equivalence.

When sourcing alternatives, verify that the substitute part maintains the same base product number (MAX1202) and meets all specified supply voltage ranges, sampling rate performance, and input channel configurations. Through-hole 20-DIP packaging ensures mechanical compatibility with existing PCB designs.

Compliance certifications (RoHS3, MSL 1) must be maintained to support production and regulatory requirements. Active product status confirms ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the MAX1202AEPP+?

A: A valid substitute must match all critical electrical parameters: 12-bit resolution, 133 kSPS sampling rate, 4/8 configurable input channels, SPI interface, SAR architecture, external/internal reference support, ±5V/5V analog supply, 2.7V–5.25V digital supply, -40°C to 85°C operating range, and 20-DIP through-hole packaging. Compliance certifications (RoHS3, MSL 1) must also be identical.

Q: Can I use a different package type as a substitute?

A: No. The MAX1202AEPP+ is specified for 20-DIP (0.300", 7.62mm) through-hole mounting. Different package types are not interchangeable without PCB redesign and re-qualification.

Q: Are there any differences in supply voltage requirements between substitute parts?

A: All qualified substitutes maintain identical supply voltage specifications: analog supply of ±5V or 5V, and digital supply of 2.7V to 5.25V. Verify your power supply design accommodates these ranges.

Q: What is the significance of the SPI data interface for substitution?

A: The SPI interface is a critical functional parameter. Any substitute must support SPI serial communication to maintain firmware and hardware compatibility with existing designs. Alternative interfaces are not acceptable substitutes.

Q: Does the sampling rate of 133 kSPS affect substitute selection?

A: Yes. The 133 kSPS sampling rate is a core performance specification. Substitutes must meet or exceed this rate. Lower sampling rates would not qualify as functional equivalents.

Q: Why is the 20-DIP package important for substitution?

A: The 20-DIP package determines physical compatibility with PCB layouts and socket designs. Through-hole mounting is specific to this package type. Surface-mount or different DIP variants require PCB redesign.

Q: What does RoHS3 compliance mean for substitute parts?

A: RoHS3 compliance certifies that the component meets European Union restrictions on hazardous substances. All substitutes must maintain this certification to ensure regulatory compliance in production and end-use applications.
