MAX4433ESA Equivalent & Substitute Parts Reference

Part Overview

The MAX4433ESA is a general-purpose operational amplifier featuring dual circuits in an 8-SOIC surface mount package, manufactured by Analog Devices Inc./Maxim Integrated. This device delivers a slew rate of 145 V/µs and -3dB bandwidth of 215 MHz, suitable for general-purpose amplification applications requiring moderate to high-speed performance.

The MAX4433ESA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this amplifier topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4433ESA 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 compatibility without layout modifications.

Dual-Circuit Configuration: The main part contains 2 circuits; substitute parts must maintain this dual-circuit topology to preserve functional equivalence in multi-channel applications.

Operating Temperature Range: The MAX4433ESA operates from -40°C to 85°C. Substitute parts must support this temperature range or a compatible extended range to ensure reliable operation across specified environmental conditions.

Supply Voltage Compatibility: The MAX4433ESA requires a supply voltage span of 9 V to 11 V. Substitute parts must accommodate this voltage range within their specified supply voltage limits.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating to satisfy procurement and manufacturing requirements.

The three substitute parts listed below meet these core substitution criteria while offering variations in performance characteristics such as slew rate, bandwidth, and output current capability.

Parameter Comparison

Engineering Selection Recommendations

AD8017ARZ (Analog Devices Inc.): This part is actively manufactured and maintains full compatibility with the MAX4433ESA supply voltage range (4.4 V to 12 V encompasses the 9 V to 11 V requirement). The AD8017ARZ offers significantly higher slew rate (1600 V/µs) and output current capability (270 mA per channel), making it suitable for applications requiring enhanced dynamic performance. Operating temperature range matches the MAX4433ESA specification. ROHS3 compliance and MSL 1 rating are maintained.

THS4222D (Texas Instruments): This actively produced device provides rail-to-rail output capability and operates across a wide supply voltage range (2.7 V to 15 V), fully accommodating the MAX4433ESA voltage requirements. The THS4222D delivers -3dB bandwidth of 230 MHz, closely matching the original part's 215 MHz specification. Operating temperature range aligns with MAX4433ESA requirements. ROHS3 compliance and MSL 1 rating are satisfied. The voltage feedback topology and rail-to-rail output may provide advantages in low-voltage or single-supply applications.

TL072CDT (STMicroelectronics): This actively manufactured J-FET amplifier offers the lowest input bias current (20 pA) and lowest supply current (1.4 mA), advantageous for low-noise and low-power applications. However, the operating temperature range is limited to 0°C to 70°C, which does not fully cover the MAX4433ESA specification of -40°C to 85°C. The slew rate (16 V/µs) and bandwidth (4 MHz) are substantially lower than the original part. This substitute is suitable only for applications not requiring the full -40°C to 85°C temperature range and where lower bandwidth is acceptable. ROHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can the AD8017ARZ directly replace the MAX4433ESA without circuit modifications?

A: The AD8017ARZ is pin-compatible in the 8-SOIC package and maintains the dual-circuit configuration. However, the significantly higher slew rate (1600 V/µs versus 145 V/µs) and output current capability (270 mA versus 60 mA) may require circuit validation to ensure stability and prevent unintended signal overshoot in existing designs. Supply voltage compatibility is confirmed within the specified range.

Q: Is the THS4222D suitable for applications requiring the full -40°C to 85°C operating temperature range?

A: Yes. The THS4222D operates from -40°C to 85°C, matching the MAX4433ESA temperature specification. The rail-to-rail output topology provides additional flexibility in single-supply or low-voltage applications.

Q: Why does the TL072CDT have a limited operating temperature range?

A: The TL072CDT is specified for 0°C to 70°C operation. Applications requiring the full -40°C to 85°C range of the MAX4433ESA must use either the AD8017ARZ or THS4222D.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts (AD8017ARZ, THS4222D, and TL072CDT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the MAX4433ESA compliance profile.

Q: What is the primary difference between the AD8017ARZ and THS4222D?

A: The AD8017ARZ is a general-purpose amplifier with higher slew rate (1600 V/µs) and output current (270 mA per channel). The THS4222D is a voltage feedback amplifier with rail-to-rail output capability, lower input bias current (900 nA), and slightly higher bandwidth (230 MHz). Selection depends on whether rail-to-rail output or maximum output current is required.

Q: Can the TL072CDT be used in high-frequency applications?

A: No. The TL072CDT has a -3dB bandwidth of only 4 MHz, substantially lower than the MAX4433ESA (215 MHz). It is unsuitable for applications requiring the original part's high-frequency performance.

Q: Are there any supply voltage restrictions when substituting these parts?

A: The MAX4433ESA requires 9 V to 11 V supply. All three substitutes accommodate this range: AD8017ARZ (4.4 V to 12 V), THS4222D (2.7 V to 15 V), and TL072CDT (6 V to 36 V). Verify that your circuit design does not depend on the narrow supply range of the original part.
