Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC4502CDR are identified based on strict electrical and mechanical compatibility criteria. The following parameters define substitution eligibility:

Mandatory Matching Parameters:

• Number of Circuits: 2
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Output Type: Rail-to-Rail (primary requirement)
• RoHS3 Compliance: Required
• Product Status: Active

Electrical Parameter Ranges for Substitution:

• Voltage - Supply Span (Min): Must support 4V minimum
• Voltage - Supply Span (Max): Must support 6V maximum
• Current - Output / Channel: Must equal or exceed 50 mA
• Slew Rate: Must support 2.5 V/µs or higher
• Gain Bandwidth Product: Must support 4.7 MHz or higher

The three substitute parts (MAX4252ESA+, MAX4257ESA+, MAX4282ESA+) meet these mandatory criteria and operate within the specified electrical parameter envelope. All substitutes are manufactured by Analog Devices Inc./Maxim Integrated, maintain Active product status, and carry ROHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and full ROHS3 compliance, meeting baseline engineering requirements for component selection. The following observations are based on provided specifications:

MAX4252ESA+: This substitute provides rail-to-rail output capability with push-pull configuration in the identical 8-SOIC package. The part operates within the required supply voltage range and delivers 68 mA output current per channel, exceeding the 50 mA requirement. Extended operating temperature range (-40°C to 85°C) accommodates broader environmental conditions compared to the TLC4502CDR.

MAX4257ESA+: This substitute offers the highest gain bandwidth product (22 MHz) among the three alternatives, with slew rate of 2.1 V/µs. Push-pull, rail-to-rail output configuration is maintained in the 8-SOIC package. Output current per channel reaches 68 mA. Extended operating temperature range and reduced supply current (420 µA per channel) are provided.

MAX4282ESA+: This substitute features the GainAmp™ series designation and delivers rail-to-rail output in the 8-SOIC package. Output current per channel is 65 mA. Supply current is reduced to 320 µA per channel. Extended operating temperature range (-40°C to 85°C) is supported. Gain bandwidth product is 2 MHz with slew rate of 0.7 V/µs.

All substitutes are available in Tube packaging with confirmed inventory levels and maintain identical mechanical compatibility with the original TLC4502CDR footprint.

Frequently Asked Questions (FAQ)

Q: Can MAX4252ESA+ directly replace TLC4502CDR in existing PCB designs?

A: Yes. Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging with the same pinout configuration for dual-circuit amplifier applications. Mechanical compatibility is confirmed. Electrical parameters fall within acceptable substitution ranges for rail-to-rail amplifier applications.

Q: What is the primary difference between MAX4257ESA+ and MAX4282ESA+?

A: MAX4257ESA+ provides higher gain bandwidth product (22 MHz) and faster slew rate (2.1 V/µs) compared to MAX4282ESA+ (2 MHz, 0.7 V/µs). MAX4282ESA+ features lower supply current consumption (320 µA per channel versus 420 µA). Selection depends on application bandwidth requirements and power budget constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MAX4252ESA+, MAX4257ESA+, and MAX4282ESA+ all carry ROHS3 Compliant certification, matching the compliance status of TLC4502CDR.

Q: What is the operating temperature difference between TLC4502CDR and the substitutes?

A: TLC4502CDR operates from 0°C to 70°C. All three substitute parts operate from -40°C to 85°C, providing extended temperature range capability. Applications requiring operation below 0°C or above 70°C must use substitute parts.

Q: Do the substitute parts support the same supply voltage range as TLC4502CDR?

A: TLC4502CDR requires 4V to 6V supply. MAX4252ESA+ and MAX4257ESA+ support 2.4V to 5.5V, and MAX4282ESA+ supports 2.5V to 5.5V. All substitutes operate within the 4V to 6V range specified for TLC4502CDR. Designs operating below 4V require MAX4252ESA+, MAX4257ESA+, or MAX4282ESA+.

Q: Which substitute provides the lowest power consumption?

A: MAX4282ESA+ delivers the lowest supply current at 320 µA per channel (x2 channels = 640 µA total), compared to TLC4502CDR at 2.5 mA per channel (5 mA total). MAX4252ESA+ and MAX4257ESA+ both consume 420 µA per channel (840 µA total).

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

A: Yes. TLC4502CDR and all three substitutes are supplied in 8-SOIC surface mount packages with identical mechanical dimensions (0.154", 3.90mm Width). MAX4252ESA+, MAX4257ESA+, and MAX4282ESA+ are packaged in Tube format.
