MAX4304ESA-T Equivalent & Substitute Parts

Part Overview

The MAX4304ESA-T is a voltage feedback amplifier integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. This single-circuit operational amplifier is housed in an 8-SOIC surface mount package and delivers high-speed performance with a 1000V/µs slew rate and 740 MHz bandwidth. The device operates across a 7V to 11V supply range and is specified for industrial temperature applications from -40°C to 85°C.

The MAX4304ESA-T carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design flexibility is required for long-term production continuity. Suitable alternatives must maintain electrical compatibility across critical performance parameters while conforming to the same physical package footprint.

Substitute Part Grouping Explanation

Substitute components for the MAX4304ESA-T are identified based on strict electrical and mechanical compatibility criteria. The substitution logic is structured as follows:

Primary Substitution Criterion (Packaging & Pinout): All substitute parts must use the 8-SOIC surface mount package with identical 0.154" (3.90mm) width to ensure direct board-level compatibility without layout modifications.

Secondary Substitution Criteria (Electrical Performance): Substitute amplifiers must operate as voltage feedback topologies with single-circuit configuration. The following electrical parameters establish the substitution boundary:

• Slew Rate: Minimum 1000V/µs (equal or greater performance acceptable)
• Bandwidth (-3dB): Minimum 740 MHz (equal or greater performance acceptable)
• Input Bias Current: Maximum 32 µA (lower values acceptable)
• Input Offset Voltage: Maximum 1 mV (lower values acceptable)
• Supply Current: Maximum 20 mA (lower values acceptable)
• Output Current per Channel: Minimum 70 mA (equal or greater performance acceptable)
• Supply Voltage Range: Must encompass or exceed 7V to 11V span
• Operating Temperature: Must support -40°C to 85°C range

Compliance & Regulatory Criteria: All substitute parts must maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status to satisfy manufacturing and environmental requirements.

Parameter Comparison

Engineering Selection Recommendations

MAX4304ESA+T (Direct Substitute): The MAX4304ESA+T is the direct functional equivalent of the MAX4304ESA-T. Both parts share identical electrical specifications, package configuration, and operating parameters. The primary distinction is product status: MAX4304ESA+T maintains Active status while MAX4304ESA-T is Obsolete. The MAX4304ESA+T is supplied in Tape & Reel packaging format, suitable for automated assembly processes. This part is the preferred choice when direct replacement is required without any design modifications. Inventory availability is significantly higher (5911 pcs vs. 618 pcs), supporting production continuity.

THS4271D (Cross-Manufacturer Alternative): The THS4271D, manufactured by Texas Instruments, qualifies as a substitute based on electrical parameter compatibility and package equivalence. This device exceeds the minimum performance requirements in several categories: bandwidth extends to 1400 MHz (versus 740 MHz), output current capability reaches 160 mA (versus 70 mA), and input bias current is reduced to 6 µA (versus 32 µA). The supply voltage range is broader (5V to 15V versus 7V to 11V), providing additional design flexibility. However, input offset voltage is specified at 5 mV, which exceeds the 1 mV specification of the MAX4304ESA-T. All regulatory and compliance certifications align with the original part. Selection of THS4271D is appropriate when enhanced performance margins or broader supply voltage tolerance are beneficial to the application.

Frequently Asked Questions (FAQ)

Q: Can MAX4304ESA+T be used as a direct replacement for MAX4304ESA-T?

A: Yes. The MAX4304ESA+T is electrically and mechanically identical to MAX4304ESA-T. Both parts feature identical slew rate (1000V/µs), bandwidth (740 MHz), input bias current (32 µA), input offset voltage (1 mV), supply current (20 mA), output current (70 mA), supply voltage range (7V to 11V), and operating temperature range (-40°C to 85°C). The 8-SOIC package footprint is identical. The only difference is product status (Active versus Obsolete) and packaging format (Tape & Reel versus individual packaging). No circuit modifications or board layout changes are required.

Q: What are the key differences between MAX4304ESA-T and THS4271D?

A: Both parts are voltage feedback amplifiers in 8-SOIC packages with identical slew rate (1000V/µs) and operating temperature range (-40°C to 85°C). THS4271D provides superior performance in three areas: bandwidth is 1400 MHz (versus 740 MHz), output current is 160 mA (versus 70 mA), and input bias current is 6 µA (versus 32 µA). THS4271D accepts a broader supply voltage range (5V to 15V versus 7V to 11V). The trade-off is input offset voltage: THS4271D specifies 5 mV compared to 1 mV for MAX4304ESA-T. Both parts are ROHS3 compliant with MSL Level 1 rating.

Q: Is the THS4271D suitable for applications requiring the 1 mV input offset voltage specification?

A: No. The THS4271D input offset voltage is specified at 5 mV, which exceeds the 1 mV requirement of MAX4304ESA-T. Applications with strict input offset voltage tolerance must use MAX4304ESA-T or MAX4304ESA+T. The THS4271D is appropriate only when input offset voltage tolerance of 5 mV is acceptable to the circuit design.

Q: Are all substitute parts available in the same packaging format?

A: No. MAX4304ESA-T and MAX4304ESA+T share the 8-SOIC surface mount package but differ in distribution packaging: MAX4304ESA-T uses standard packaging while MAX4304ESA+T is supplied in Tape & Reel format for automated assembly. THS4271D is supplied in Tube packaging. All three parts use identical component-level 8-SOIC (0.154", 3.90mm width) packages suitable for the same PCB footprint.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. MAX4304ESA-T, MAX4304ESA+T, and THS4271D are all ROHS3 compliant, carry MSL Level 1 (Unlimited) moisture sensitivity rating, and maintain REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001. Compliance certifications are equivalent across all three parts.

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

A: For new designs requiring the exact electrical specifications of MAX4304ESA-T (including 1 mV input offset voltage), use MAX4304ESA+T. This part is in Active production status with higher inventory availability. For new designs where enhanced performance (higher bandwidth, lower input bias current, higher output current) is beneficial and 5 mV input offset voltage is acceptable, THS4271D provides a cross-manufacturer alternative with broader supply voltage tolerance.
