MAX533ACEE Equivalent & Substitute Parts

Part Overview

The MAX533ACEE is an 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated, featuring four independent DAC channels with voltage-buffered outputs. This component operates as a String DAC architecture with SPI data interface and external voltage reference capability. The MAX533ACEE is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or production continuity. The part is housed in a 16-QSOP surface mount package and operates across analog and digital supply voltages of 2.7V to 3.6V.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX533ACEE is determined by strict equivalence across the following critical parameters:

• Resolution and Channel Count: 8-bit resolution with 4 independent DAC channels
• Output Configuration: Voltage-buffered output topology
• Interface Protocol: SPI serial data interface
• Supply Voltage Range: Dual supply rails (analog and digital) operating at 2.7V to 3.6V
• Linearity Performance: INL/DNL specifications of ±1 LSB maximum
• Settling Time: 6µs typical response time
• Package Compatibility: 16-QSOP surface mount package with 0.154" width (3.90mm)
• Reference Architecture: External voltage reference requirement

The MAX533ACEE+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MAX533ACEE+ is the direct functional equivalent of the MAX533ACEE, with identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the MAX533ACEE is obsolete while the MAX533ACEE+ maintains active production status. Additionally, the MAX533ACEE+ achieves ROHS3 compliance, whereas the original MAX533ACEE does not meet RoHS requirements. For new designs or production continuity where the MAX533ACEE is no longer available, the MAX533ACEE+ provides complete electrical and physical compatibility without design modification. Both parts share identical packaging, pinout, and performance characteristics across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can MAX533ACEE+ be used as a direct replacement for MAX533ACEE in existing designs?

A: Yes. The MAX533ACEE+ is electrically and mechanically identical to the MAX533ACEE. No circuit modifications, firmware changes, or PCB layout adjustments are required. Both parts feature identical pin configurations, supply voltage requirements, SPI interface timing, and output characteristics.

Q: What is the significance of the "+" suffix in MAX533ACEE+?

A: The "+" suffix indicates packaging format and compliance status. The MAX533ACEE+ is supplied in tube packaging and meets ROHS3 environmental compliance standards, whereas the original MAX533ACEE does not carry RoHS certification.

Q: Are there any performance differences between MAX533ACEE and MAX533ACEE+?

A: No performance differences exist. Both parts deliver identical settling time (6µs typical), linearity (±1 LSB INL/DNL), resolution (8-bit), channel count (4 DACs), and operating temperature range (0°C to 70°C).

Q: What is the package compatibility between these parts?

A: Both the MAX533ACEE and MAX533ACEE+ use the 16-QSOP package with identical dimensions (0.154" width, 3.90mm). They are pin-for-pin compatible and mount identically on PCBs designed for either part number.

Q: Why is the MAX533ACEE classified as obsolete?

A: The MAX533ACEE has reached end-of-life status in Analog Devices' product portfolio. The MAX533ACEE+ represents the current active production equivalent and should be specified for all new designs.
