MAX452CSA Equivalent & Substitute Parts

Part Overview

The MAX452CSA is a voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for video amplification applications. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing system support and new designs. The MAX452CSA operates as a single-channel voltage feedback amplifier in an 8-SOIC surface mount package, delivering 50 MHz bandwidth with 300V/µs slew rate capability. Due to its obsolete status, equivalent parts with active product status are required for procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX452CSA is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Electrical Performance Envelope: Substitute parts must operate within or exceed the supply voltage range and deliver equivalent or superior bandwidth and slew rate performance. The MAX452CSA operates at ±4.5V to ±5.5V with 50 MHz bandwidth; substitutes must support these voltage levels or provide compatible alternatives.

Circuit Configuration: All substitutes must be single-channel amplifiers (1 circuit) to match the original functional architecture.

Amplifier Type: Voltage feedback topology is the primary substitution criterion, though variable gain and differential output variants are listed as functional alternatives for specific application requirements.

Compliance Status: Due to the obsolete status of the MAX452CSA, active product status substitutes with RoHS3 compliance are preferred for new designs and long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Performance):

MAX452CSA+ is the direct equivalent with identical electrical specifications (50 MHz bandwidth, 300V/µs slew rate, 25 mA supply current). This part maintains the same functional characteristics as the original MAX452CSA while offering ROHS3 compliance and improved availability. Selection of MAX452CSA+ is appropriate for designs requiring exact performance matching and minimal circuit redesign.

Active Product Substitutes (Enhanced Performance):

AD8048ARZ, LMH6505MA/NOPB, LMH6550MA/NOPB, OPA656U/2K5, and OPA656UB/2K5 are all active product status components suitable for new designs and long-term procurement. These parts deliver superior bandwidth and slew rate performance compared to the MAX452CSA while maintaining 8-SOIC package compatibility.

AD8048ARZ provides 260 MHz bandwidth with 1000V/µs slew rate and ROHS3 compliance. This part operates at 6V to 12V supply range and is suitable for applications requiring higher bandwidth than the original MAX452CSA.

LMH6505MA/NOPB is a variable gain amplifier offering 150 MHz bandwidth with 1500V/µs slew rate. This part is appropriate for applications requiring programmable gain control within the 7V to 12V supply range.

LMH6550MA/NOPB is a differential output amplifier with 400 MHz bandwidth and 3000V/µs slew rate, suitable for high-speed differential signal applications. This part operates at 4.5V to 12V supply range, overlapping with the original MAX452CSA voltage specification.

OPA656U/2K5 and OPA656UB/2K5 are wideband voltage feedback amplifiers with 500 MHz bandwidth and 295V/µs slew rate. These parts feature extremely low input bias current (2 pA and 1 pA respectively) and operate at 8V to 12V supply range. OPA656UB/2K5 carries ROHS3 compliance certification.

Compliance Considerations:

For new designs subject to RoHS3 requirements, MAX452CSA+, AD8048ARZ, and OPA656UB/2K5 are compliant options. The original MAX452CSA is RoHS non-compliant and should not be used in new designs requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can MAX452CSA+ be used as a direct replacement for MAX452CSA?

A: Yes. MAX452CSA+ is electrically identical to MAX452CSA with the same 50 MHz bandwidth, 300V/µs slew rate, and ±4.5V to ±5.5V supply range. The primary difference is improved RoHS3 compliance status. PCB footprint and pin configuration are identical, requiring no circuit modifications.

Q: What is the key difference between MAX452CSA and AD8048ARZ?

A: AD8048ARZ offers significantly higher bandwidth (260 MHz versus 50 MHz) and slew rate (1000V/µs versus 300V/µs). However, AD8048ARZ requires a minimum 6V supply voltage, whereas MAX452CSA operates at ±4.5V. For applications operating at lower supply voltages, MAX452CSA+ or LMH6550MA/NOPB are more appropriate.

Q: Are all substitute parts available in the same 8-SOIC package?

A: Yes. All substitute parts listed are available in 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring direct PCB footprint compatibility without layout modifications.

Q: What is the difference between OPA656U/2K5 and OPA656UB/2K5?

A: Both parts are electrically identical with 500 MHz bandwidth and 295V/µs slew rate. The primary difference is that OPA656UB/2K5 carries ROHS3 compliance certification, while OPA656U/2K5 compliance status is not specified. For new designs, OPA656UB/2K5 is recommended.

Q: Can LMH6550MA/NOPB be used in applications requiring single-ended output?

A: LMH6550MA/NOPB is specified as a differential output amplifier. While differential amplifiers can be configured for single-ended operation through appropriate circuit design, this requires additional design consideration. For straightforward single-ended applications, OPA656UB/2K5 or AD8048ARZ are more suitable.

Q: What supply voltage range should be used when substituting with AD8048ARZ?

A: AD8048ARZ operates at 6V to 12V supply range. The original MAX452CSA operates at ±4.5V to ±5.5V. When substituting AD8048ARZ, the circuit power supply must be redesigned to provide minimum 6V supply voltage. This may require circuit modifications.

Q: Is LMH6505MA/NOPB suitable for fixed-gain applications?

A: Yes. LMH6505MA/NOPB is a variable gain amplifier that can be configured for fixed-gain operation through appropriate feedback network design. The variable gain capability provides additional design flexibility compared to fixed-gain amplifiers, but does not preclude fixed-gain configuration.

Q: What is the moisture sensitivity level (MSL) for substitute parts?

A: MAX452CSA, MAX452CSA+, and most substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. OPA656UB/2K5 carries MSL 3 (168 Hours), requiring controlled storage and handling procedures during manufacturing.

Q: Can substitute parts be mixed within a single design?

A: Mixing substitute parts within a single design is not recommended. Each substitute part has different electrical characteristics (bandwidth, slew rate, supply current). Using different parts in parallel or cascaded configurations may result in unpredictable circuit behavior. Standardize on a single substitute part per design.

Q: What is the inventory status for substitute parts?

A: MAX452CSA+ (2180 pcs), AD8048ARZ (4632 pcs), LMH6505MA/NOPB (1500 pcs), LMH6550MA/NOPB (1613 pcs), OPA656U/2K5 (65980 pcs), and OPA656UB/2K5 (3200 pcs) are available in stock. OPA656U/2K5 has the highest inventory availability.
