MAX4216EUA Equivalent & Substitute Parts

Part Overview

The MAX4216EUA is a voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This dual-channel operational amplifier features rail-to-rail output capability in an 8-uMAX/uSOP surface mount package. The device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production requirements. Substitute parts must maintain functional compatibility across critical electrical parameters including slew rate, bandwidth, supply voltage range, and output current specifications.

Engineering Selection Recommendations

MAX4216EUA+ (Direct Substitute):

The MAX4216EUA+ is the direct equivalent of the MAX4216EUA, manufactured by the same supplier (Analog Devices Inc./Maxim Integrated). This part maintains identical electrical specifications across all critical parameters: slew rate (600 V/µs), bandwidth (200 MHz), supply current (5.5 mA per channel), and output current (120 mA per channel). The primary distinction is product status: MAX4216EUA+ is classified as Active, whereas the original MAX4216EUA is Obsolete. Additionally, MAX4216EUA+ carries ROHS3 compliance certification, whereas the original part is non-compliant. The packaging and pinout are identical, enabling direct substitution without circuit modification. This part is recommended for applications requiring exact electrical performance matching and continued supplier support.

THS4222DGK (Alternative Substitute):

The THS4222DGK, manufactured by Texas Instruments, is a functionally compatible alternative that meets or exceeds the electrical requirements of the MAX4216EUA. This device demonstrates superior performance in several parameters: slew rate (990 V/µs versus 600 V/µs), bandwidth (-3dB at 230 MHz versus 200 MHz), and input bias current (900 nA versus 5.4 µA). The THS4222DGK supports an expanded supply voltage range (2.7 V to 15 V versus 3.15 V to 11 V), providing greater design flexibility. The output current per channel is 100 mA, which is 20 mA lower than the MAX4216EUA specification. Both devices are classified as Active products with ROHS3 compliance. The THS4222DGK is suitable for applications where enhanced performance characteristics and broader supply voltage compatibility are beneficial, provided the 100 mA output current specification is adequate for the application.

Frequently Asked Questions (FAQ)

Q1: Can MAX4216EUA+ be used as a direct replacement for MAX4216EUA?

A: Yes. The MAX4216EUA+ is the direct equivalent part. Both devices share identical electrical specifications, pinout, and package configuration. The primary differences are product status (Active versus Obsolete) and RoHS compliance (ROHS3 versus non-compliant). No circuit modifications are required for substitution.

Q2: What are the key differences between MAX4216EUA and THS4222DGK?

A: Both devices are dual-channel voltage feedback amplifiers with rail-to-rail output in 8-pin surface mount packages. The THS4222DGK offers superior slew rate (990 V/µs versus 600 V/µs), higher bandwidth (230 MHz versus 200 MHz), significantly lower input bias current (900 nA versus 5.4 µA), and expanded supply voltage range (2.7 V to 15 V versus 3.15 V to 11 V). The THS4222DGK output current per channel is 100 mA compared to 120 mA for the MAX4216EUA. Both operate across the same temperature range (-40°C to 85°C).

Q3: Is the THS4222DGK pin-compatible with MAX4216EUA?

A: Both devices use 8-pin surface mount packages (8-TSSOP/8-MSOP configuration with 0.118" width, 3.00mm). Physical package compatibility is confirmed. However, pinout compatibility must be verified against specific device datasheets before implementation, as package type alone does not guarantee identical pin assignments.

Q4: Which substitute part should be selected for new designs?

A: For new designs, MAX4216EUA+ is recommended if exact electrical performance matching is required. The THS4222DGK is suitable if enhanced performance characteristics (higher slew rate, lower input bias current, expanded supply range) are beneficial and the 100 mA output current specification is adequate. Both parts are Active products with current manufacturer support and ROHS3 compliance.

Q5: Are there supply voltage compatibility concerns when substituting with THS4222DGK?

A: The THS4222DGK supports a broader supply voltage range (2.7 V to 15 V) compared to MAX4216EUA (3.15 V to 11 V). Applications operating within the original 3.15 V to 11 V range will function correctly with THS4222DGK. Applications requiring operation below 3.15 V or above 11 V may benefit from the expanded range, but circuit design verification is necessary.

Q6: What is the significance of the 20 mA output current difference between MAX4216EUA and THS4222DGK?

A: The MAX4216EUA provides 120 mA output current per channel, while THS4222DGK provides 100 mA per channel. Applications requiring output currents exceeding 100 mA per channel must retain the MAX4216EUA or MAX4216EUA+. Applications with output current requirements of 100 mA or less are compatible with THS4222DGK.

Q7: Do both substitute parts meet RoHS compliance requirements?

A: MAX4216EUA+ and THS4222DGK are both ROHS3 compliant. The original MAX4216EUA is non-compliant. For applications subject to RoHS regulatory requirements, either substitute part is acceptable.
