Substitute Part Grouping Explanation

Substitution of the MAX452CSA+ is determined by strict adherence to the following electrical and mechanical criteria:

Primary Substitution Criteria:

Package compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount only
Amplifier topology: Voltage feedback configuration
Single circuit configuration (1 amplifier per package)
Supply voltage compatibility: Devices must operate within or encompass the ±4.5V to ±5.5V range
Output current capability: Minimum 20 mA per channel
Supply current: Maximum 25 mA acceptable for direct drop-in replacement

Secondary Compatibility Parameters:

Bandwidth performance: Minimum 50 MHz -3dB bandwidth
Slew rate: Minimum 300V/µs
RoHS3 compliance required
Surface mount 8-SOIC package mandatory

The substitute parts listed (AD8048ARZ, LMH6505MA/NOPB, OPA656U/2K5, OPA656UB/2K5) meet the mechanical packaging requirement and amplifier classification. However, each exhibits different electrical performance characteristics that must be evaluated against specific application requirements.

Engineering Selection Recommendations

AD8048ARZ (Analog Devices Inc.) Active product status with ROHS3 compliance. Exceeds bandwidth requirement at 260 MHz and slew rate at 1000V/µs. Supply current reduced to 5.9 mA. Output current capability increased to 50 mA. Supply voltage range 6V to 12V encompasses the original ±4.5V to ±5.5V specification. Suitable for applications requiring enhanced performance margins and reduced power consumption.

LMH6505MA/NOPB (Texas Instruments) Active product status with ROHS3 compliance. Variable gain amplifier topology differs from original voltage feedback configuration. Bandwidth 150 MHz and slew rate 1500V/µs exceed original specifications. Supply voltage range 7V to 12V. Output current 80 mA. Supply current 11 mA. Appropriate for applications requiring programmable gain functionality with higher performance specifications.

OPA656U/2K5 (Burr Brown) Active product status. Bandwidth 500 MHz and slew rate 295V/µs closely match original performance envelope. Supply voltage range 8V to 12V. Output current 70 mA. Supply current 14 mA. RoHS status not specified in provided data. Suitable for wideband applications requiring unity gain stability.

OPA656UB/2K5 (Texas Instruments) Active product status with ROHS3 compliance. Bandwidth 500 MHz and slew rate 295V/µs match original performance. Supply voltage range 8V to 12V. Output current 70 mA. Supply current 14 mA. Moisture sensitivity level MSL-3 (168 hours). Functionally equivalent to OPA656U/2K5 with confirmed compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the AD8048ARZ directly replace the MAX452CSA+ in existing designs? A: The AD8048ARZ shares the 8-SOIC package and voltage feedback topology. However, the supply voltage minimum of 6V differs from the original ±4.5V specification. Designs operating at ±4.5V require circuit modification or alternative selection. The enhanced bandwidth (260 MHz vs. 50 MHz) and slew rate (1000V/µs vs. 300V/µs) are compatible with applications designed for the original part.

Q: What is the primary difference between OPA656U/2K5 and OPA656UB/2K5? A: Both devices share identical electrical specifications: 500 MHz bandwidth, 295V/µs slew rate, and 8-SOIC packaging. The OPA656UB/2K5 is manufactured by Texas Instruments with confirmed ROHS3 compliance and MSL-3 moisture sensitivity rating. The OPA656U/2K5 is manufactured by Burr Brown with unspecified RoHS status. For new designs requiring compliance documentation, OPA656UB/2K5 is preferred.

Q: Is the LMH6505MA/NOPB suitable for fixed-gain applications? A: The LMH6505MA/NOPB is classified as a variable gain amplifier. While it can operate in fixed-gain configurations, the original MAX452CSA+ is a voltage feedback amplifier without gain programming capability. The LMH6505MA/NOPB introduces additional complexity through gain control circuitry. Selection depends on whether the application requires programmable gain functionality.

Q: What supply voltage range is compatible with all substitute parts? A: No single substitute part operates across the complete original range of ±4.5V to ±5.5V. The AD8048ARZ minimum supply is 6V (±3V). The LMH6505MA/NOPB minimum is 7V (±3.5V). The OPA656 variants require 8V minimum (±4V). Applications constrained to ±4.5V operation must retain the MAX452CSA+ or evaluate circuit redesign.

Q: Are all substitute parts RoHS3 compliant? A: AD8048ARZ, LMH6505MA/NOPB, and OPA656UB/2K5 are confirmed ROHS3 compliant. The OPA656U/2K5 RoHS status is not specified in the provided data. For applications requiring RoHS3 compliance documentation, AD8048ARZ, LMH6505MA/NOPB, or OPA656UB/2K5 are appropriate selections.

Q: Can the MAX452CSA+ be sourced as a new component? A: The MAX452CSA+ is classified as obsolete. Current inventory of 2180 pieces is available as new original stock. Long-term production availability is not guaranteed. New designs should incorporate one of the active substitute parts to ensure supply chain continuity and future component availability.
