MAX4216ESA Equivalent & Substitute Parts

Part Overview

The MAX4216ESA is a voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, containing two circuits in a rail-to-rail configuration. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production requirements. The MAX4216ESA operates across a supply voltage range of 3.15 V to 11 V and is housed in an 8-SOIC surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4216ESA is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Amplifier Type: Voltage Feedback
• Number of Circuits: 2
• Output Type: Rail-to-Rail
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 85°C

Acceptable Parameter Variations: Substitute parts may exceed the following specifications of the MAX4216ESA without functional degradation:

• Slew Rate (minimum 600 V/µs required)
• -3dB Bandwidth (minimum 200 MHz required)
• Current - Input Bias (lower values acceptable)
• Voltage - Input Offset (lower values acceptable)
• Current - Supply (higher values acceptable)
• Current - Output / Channel (higher values acceptable)
• Voltage - Supply Span (wider ranges acceptable)

Non-Negotiable Parameters: Supply voltage range minimum must not fall below 3.15 V. Package footprint and pinout must remain identical for direct PCB compatibility.

Engineering Selection Recommendations

MAX4216ESA+ (Direct Manufacturer Upgrade)

The MAX4216ESA+ is the direct successor to the MAX4216ESA from Analog Devices Inc./Maxim Integrated. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. The MAX4216ESA+ is the preferred substitution path for designs currently using the obsolete MAX4216ESA, as it requires no circuit redesign and provides full backward compatibility. Inventory availability is significantly higher at 12,700 pieces.

THS4222D and THS4222DR (Texas Instruments Alternatives)

The THS4222D and THS4222DR from Texas Instruments are functionally equivalent voltage feedback amplifiers with two circuits in 8-SOIC rail-to-rail configuration. These parts exceed the performance specifications of the MAX4216ESA in slew rate (990 V/µs versus 600 V/µs) and bandwidth (230 MHz versus 200 MHz). Both THS4222 variants demonstrate superior input bias current (900 nA versus 5.4 µA) and lower input offset voltage (3 mV versus 4 mV). The wider supply voltage range (2.7 V to 15 V) provides additional design flexibility. Both variants are ROHS3 compliant and carry active product status. Selection between THS4222D and THS4222DR depends on packaging requirements; THS4222DR is supplied in tube packaging.

Frequently Asked Questions (FAQ)

Q: Can MAX4216ESA be directly replaced with MAX4216ESA+ without PCB modifications?

A: Yes. The MAX4216ESA+ maintains identical pinout, package footprint (8-SOIC), and electrical specifications as the MAX4216ESA. Direct substitution on existing PCBs is supported without circuit redesign.

Q: What are the key differences between MAX4216ESA+ and THS4222D?

A: Both parts are pin-compatible 8-SOIC dual voltage feedback amplifiers with rail-to-rail output. The THS4222D offers higher slew rate (990 V/µs versus 600 V/µs), higher bandwidth (230 MHz versus 200 MHz), lower input bias current (900 nA versus 5.4 µA), and wider supply voltage range (2.7 V to 15 V versus 3.15 V to 11 V). The MAX4216ESA+ maintains lower supply current (5.5 mA versus 14 mA per channel).

Q: Are THS4222D and THS4222DR electrically identical?

A: Yes. THS4222D and THS4222DR are electrically identical. The designation difference reflects packaging format: THS4222D is supplied in tube packaging, while THS4222DR is supplied in reel packaging.

Q: What is the impact of higher supply current in THS4222 variants?

A: The THS4222D and THS4222DR require 14 mA per channel compared to 5.5 mA for the MAX4216ESA. This increased current consumption must be evaluated against power supply capacity and thermal management requirements in the target application.

Q: Can THS4222 parts be used in applications with 3.15 V minimum supply voltage?

A: The THS4222D and THS4222DR support minimum supply voltage of 2.7 V, which is lower than the MAX4216ESA minimum of 3.15 V. Applications operating at 3.15 V are within the THS4222 operating range and are supported.

Q: Are all substitute parts ROHS3 compliant?

A: The MAX4216ESA is RoHS non-compliant. The MAX4216ESA+, THS4222D, and THS4222DR are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the recommended substitution priority?

A: For existing MAX4216ESA designs, prioritize MAX4216ESA+ as the first choice due to identical specifications and full backward compatibility. Select THS4222D or THS4222DR only when enhanced performance specifications (higher slew rate, bandwidth, or lower input bias current) are beneficial to the application or when supply chain constraints require alternative sourcing.
