MAX1247ACPE+ Equivalent & Substitute Parts

Part Overview

The MAX1247ACPE+ is a 12-bit Analog to Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring SAR (Successive Approximation Register) architecture. This component operates as a single ADC with multiplexed input channels, supporting both differential and single-ended input configurations. The device is actively produced and widely used in industrial measurement, instrumentation, and embedded systems requiring moderate-speed analog conversion. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1247ACPE+ is determined by strict equivalence across the following critical parameters:

• Resolution & Sampling Rate: 12-bit resolution at 133 kSPS
• Input Configuration: Support for 2 or 4 multiplexed channels with differential and single-ended input capability
• Interface Protocol: SPI serial data interface
• Architecture: SAR-based conversion topology
• Supply Voltage Compatibility: Dual supply operation within 2.7V to 5.25V range for both analog and digital domains
• Package & Pinout: 16-DIP through-hole package with identical pin configuration
• Operating Temperature: 0°C to 70°C industrial range
• Regulatory Compliance: ROHS3 compliance and MSL Level 1 rating

The MAX1247BCPE+ meets all these criteria and is classified as a parametric equivalent within the MAX1247 product family.

Parameter Comparison

Engineering Selection Recommendations

Both MAX1247ACPE+ and MAX1247BCPE+ are active products from Analog Devices Inc./Maxim Integrated with identical electrical specifications and package configurations. Selection between these parts may be based on inventory availability and supply chain considerations. The MAX1247ACPE+ currently maintains 955 units in stock, while the MAX1247BCPE+ has 780 units available. Both components carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements for industrial and commercial applications. The MSL Level 1 rating for both parts indicates unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can MAX1247BCPE+ be used as a direct replacement for MAX1247ACPE+ in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including resolution, sampling rate, input configuration, supply voltage ranges, operating temperature, and package type. Direct substitution is supported without design modifications.

Q: Are there any differences in pin configuration between these parts?

A: No. Both the MAX1247ACPE+ and MAX1247BCPE+ use identical 16-DIP through-hole packaging with the same pinout. PCB layouts and socket compatibility are fully interchangeable.

Q: What determines whether a part qualifies as a substitute for the MAX1247ACPE+?

A: Substitution eligibility requires matching specifications across: 12-bit resolution, 133 kSPS sampling rate, 2/4-channel multiplexed input support, SPI interface, SAR architecture, external reference type, 2.7V–5.25V dual supply operation, 0°C–70°C operating range, and 16-DIP package format.

Q: Do both parts support the same input configurations?

A: Yes. Both MAX1247ACPE+ and MAX1247BCPE+ support differential and single-ended input modes with identical multiplexing capability across 2 or 4 channels.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH Unaffected status, and MSL Level 1 rating. Regulatory and environmental certifications are equivalent.

Q: What is the significance of the temperature range specification?

A: The 0°C–70°C operating range defines the industrial-grade temperature specification for both parts. Applications requiring extended temperature ranges would require alternative product lines from the MAX1247 family.
