Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4017ESA is determined by strict alignment of electrical performance parameters and mechanical compatibility. The following criteria establish valid substitute relationships:

Primary Substitution Criteria:

• Dual-channel configuration (Number of Circuits = 2)
• Rail-to-rail output capability
• 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Operating temperature range: -40°C to 85°C
• Supply voltage span compatibility: minimum 3.15 V, maximum 11 V

Secondary Performance Parameters:

• Slew rate, gain bandwidth product, and -3dB bandwidth determine signal fidelity in high-frequency applications
• Input bias current and input offset voltage affect precision in low-signal applications
• Output current per channel must support load requirements
• Supply current consumption impacts power budget

The MAX4017ESA+ and AD8042ARZ meet these substitution criteria with identical or superior electrical specifications and compatible packaging. Both alternatives are active products with current manufacturing status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

MAX4017ESA+ (Direct Substitute): The MAX4017ESA+ is the direct functional equivalent of the MAX4017ESA, manufactured by Analog Devices Inc./Maxim Integrated under the same base product number (MAX4017). This part maintains identical electrical specifications across all measured parameters, including slew rate (600 V/µs), gain bandwidth product (140 MHz), and output current per channel (120 mA). The MAX4017ESA+ is classified as active with current manufacturing status and RoHS3 compliance, addressing regulatory requirements for new designs. Packaging is identical (8-SOIC, 0.154", 3.90mm Width). This substitute is recommended for direct replacement in existing designs without circuit modification.

AD8042ARZ (Alternative Substitute): The AD8042ARZ is an active alternative manufactured by Analog Devices Inc. that meets core substitution criteria: dual-channel voltage feedback amplifier with rail-to-rail output in 8-SOIC surface mount package. The AD8042ARZ exhibits lower input bias current (1.2 µA versus 5.4 µA) and lower input offset voltage (3 mV versus 4 mV), providing improved precision characteristics. However, the AD8042ARZ has reduced slew rate (225 V/µs versus 600 V/µs), lower gain bandwidth product (90 MHz versus 140 MHz), and reduced output current per channel (50 mA versus 120 mA). The AD8042ARZ is RoHS3 compliant and active. This substitute is suitable for applications where lower input bias current and offset voltage are beneficial and where the reduced slew rate and bandwidth do not constrain circuit performance.

Both substitutes are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental specifications of the original part.

Frequently Asked Questions (FAQ)

Q: Can MAX4017ESA+ be used as a direct replacement for MAX4017ESA?

A: Yes. The MAX4017ESA+ is the active equivalent of the obsolete MAX4017ESA. Both parts share identical electrical specifications, including slew rate (600 V/µs), gain bandwidth product (140 MHz), input bias current (5.4 µA), and output current per channel (120 mA). Package and pinout are identical (8-SOIC, 0.154", 3.90mm Width). No circuit modifications are required for substitution.

Q: What are the key differences between MAX4017ESA+ and AD8042ARZ?

A: Both are dual-channel rail-to-rail amplifiers in 8-SOIC packages. The MAX4017ESA+ maintains identical performance to the original MAX4017ESA with 600 V/µs slew rate and 140 MHz bandwidth. The AD8042ARZ has lower input bias current (1.2 µA) and lower input offset voltage (3 mV), but reduced slew rate (225 V/µs), lower bandwidth (90 MHz), and reduced output current per channel (50 mA). Selection depends on whether precision (AD8042ARZ) or high-speed performance (MAX4017ESA+) is required.

Q: Are both substitutes compatible with the original PCB layout?

A: Yes. Both MAX4017ESA+ and AD8042ARZ use identical 8-SOIC surface mount packaging (0.154", 3.90mm Width) with the same pinout. No PCB layout modifications are necessary for either substitute.

Q: What is the supply voltage compatibility range for these substitutes?

A: MAX4017ESA+ operates across 3.15 V to 11 V supply span. AD8042ARZ operates across 3 V to 12 V supply span. Both accommodate the original MAX4017ESA supply range (3.15 V to 11 V). The AD8042ARZ provides extended lower-voltage capability (3 V minimum).

Q: Do both substitutes meet RoHS compliance requirements?

A: Yes. Both MAX4017ESA+ and AD8042ARZ are RoHS3 compliant. The original MAX4017ESA is RoHS non-compliant. For applications requiring RoHS compliance, either substitute is acceptable.

Q: Which substitute should be selected for high-frequency signal conditioning applications?

A: The MAX4017ESA+ is recommended for high-frequency applications. It maintains the original slew rate (600 V/µs) and gain bandwidth product (140 MHz), supporting faster signal transitions and higher bandwidth requirements. The AD8042ARZ, with 225 V/µs slew rate and 90 MHz bandwidth, is suitable for lower-frequency applications.

Q: Which substitute should be selected for precision low-signal applications?

A: The AD8042ARZ is recommended for precision applications. It provides lower input bias current (1.2 µA versus 5.4 µA) and lower input offset voltage (3 mV versus 4 mV), reducing errors in sensitive measurement circuits.

Q: What is the output current capability difference between the substitutes?

A: MAX4017ESA+ provides 120 mA per channel output current. AD8042ARZ provides 50 mA per channel output current. For applications requiring higher output current drive capability, MAX4017ESA+ is the appropriate selection.
