MAX5253BCAP Equivalent & Substitute Parts

Part Overview

The MAX5253BCAP is a 12-bit digital-to-analog converter (DAC) with 4 independent channels, designed for data acquisition applications requiring voltage output buffering. The device features SPI interface control, external reference capability, and operates across 3V to 3.6V supply rails with 16µs typical settling time.

The MAX5253BCAP is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX5253BCAP is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion
• Channel Count: 4 independent D/A converters
• Output Configuration: Voltage output with buffering
• Interface Protocol: SPI digital control
• Reference Input: External reference requirement
• Supply Voltage Range: 3V to 3.6V (both analog and digital rails)
• Linearity Performance: INL/DNL specifications of ± 1 LSB maximum
• Package Form Factor: 20-SSOP surface mount package
• Thermal Operating Range: 0°C to 70°C

The MAX5253BCAP+ meets all substitution criteria as a direct equivalent, differing only in product status (active vs. obsolete) and packaging format (tube vs. unspecified).

Parameter Comparison

Engineering Selection Recommendations

The MAX5253BCAP+ is the direct substitute for the MAX5253BCAP. Both parts share identical electrical specifications, pin configuration, and functional performance across all critical parameters.

The primary distinction is product lifecycle status: MAX5253BCAP is obsolete, while MAX5253BCAP+ is active. Additionally, MAX5253BCAP+ carries ROHS3 compliance certification, whereas the original MAX5253BCAP is non-compliant. For new designs or production continuity requiring regulatory compliance, MAX5253BCAP+ is the appropriate selection.

Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain equivalent performance in data acquisition applications requiring 12-bit, 4-channel voltage output DAC functionality with SPI interface control.

Frequently Asked Questions (FAQ)

Q: Can MAX5253BCAP+ directly replace MAX5253BCAP in existing designs?

A: Yes. The MAX5253BCAP+ is electrically and mechanically identical to MAX5253BCAP. Pin configuration, signal timing, and functional behavior are equivalent. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Obsolete status indicates the MAX5253BCAP is no longer manufactured or supported by Analog Devices. The MAX5253BCAP+ remains in active production, ensuring long-term availability and supply chain continuity. For ongoing production or new applications, the active part is recommended.

Q: Does RoHS3 compliance affect functional compatibility?

A: No. RoHS3 compliance is a manufacturing and material standard, not a functional specification. Both parts operate identically in circuit. RoHS3 compliance on MAX5253BCAP+ may be required for certain regulatory environments or customer specifications.

Q: Are there packaging differences between these parts?

A: Both parts use the same 20-SSOP surface mount package. The MAX5253BCAP+ is supplied in tube packaging, while the original MAX5253BCAP packaging format is unspecified in available data. This does not affect electrical performance or PCB integration.

Q: What parameters must remain constant for substitution eligibility?

A: Resolution (12-bit), channel count (4), output type (voltage-buffered), interface (SPI), reference type (external), supply voltage range (3V–3.6V), linearity (INL/DNL ± 1 LSB), package (20-SSOP), and operating temperature (0°C–70°C) must all match exactly for valid substitution.
