MAX495EPA Equivalent & Substitute Parts Reference

Part Overview

The MAX495EPA is a general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, packaged in 8-DIP through-hole configuration. This device is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and production requirements. The MAX495EPA operates as a single-circuit rail-to-rail amplifier suitable for low-power applications requiring supply voltages between 2.7 V and 6 V across an operating temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX495EPA is determined by strict adherence to the following electrical and mechanical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Voltage - Supply Span: 2.7 V minimum to 6 V maximum

Electrical Performance Boundaries: Substitute parts must operate within the specified supply voltage range (2.7 V to 6 V) and maintain rail-to-rail output capability. The TLV2461 series from Texas Instruments satisfies these core requirements while providing enhanced electrical performance characteristics including higher slew rate, increased gain bandwidth product, and lower input bias current.

Thermal Operating Range: The MAX495EPA operates from -40°C to 85°C. Substitute parts TLV2461AIP and TLV2461IP extend the upper temperature limit to 125°C, while TLV2461CP operates from 0°C to 70°C. Selection depends on application thermal requirements.

Parameter Comparison

Engineering Selection Recommendations

TLV2461CP is the primary recommended substitute for new designs and production transitions. This device maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The TLV2461CP operates within the commercial temperature range (0°C to 70°C) and is suitable for applications not requiring extended low-temperature operation below 0°C.

TLV2461AIP and TLV2461IP serve as alternatives for applications requiring extended temperature operation to -40°C and 125°C. Both devices carry Last Time Buy status, indicating limited future availability. TLV2461AIP and TLV2461IP are functionally equivalent with identical electrical specifications and both achieve ROHS3 compliance.

All three TLV2461 variants provide superior electrical performance compared to the MAX495EPA, including 8× higher slew rate (1.6 V/µs versus 0.2 V/µs), 12.8× higher gain bandwidth product (6.4 MHz versus 500 kHz), and significantly lower input bias current (1.3 nA versus 25 nA). These enhancements enable improved signal fidelity and reduced noise in precision applications.

Pin-to-pin compatibility is maintained across all substitute options due to identical 8-DIP package geometry and through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can TLV2461CP directly replace MAX495EPA in existing PCB designs?

A: Yes. The TLV2461CP maintains identical 8-DIP package dimensions (0.300", 7.62mm) and through-hole mounting configuration, enabling direct socket substitution without PCB modification. Pin assignments are compatible for general-purpose amplifier applications.

Q: What is the primary difference between TLV2461CP, TLV2461AIP, and TLV2461IP?

A: The three devices are electrically identical with respect to core amplifier specifications. The primary distinction is operating temperature range: TLV2461CP operates 0°C to 70°C (commercial), while TLV2461AIP and TLV2461IP both operate -40°C to 125°C (extended range). Product status differs, with TLV2461CP in active production and the other two designated Last Time Buy.

Q: Why does TLV2461 series show higher supply current (550 µA) compared to MAX495EPA (150 µA)?

A: The increased supply current reflects the enhanced performance characteristics of the TLV2461 series, including 8× higher slew rate and 12.8× higher gain bandwidth product. This trade-off between power consumption and performance is inherent to the device architectures and must be evaluated against application power budget requirements.

Q: Is RoHS compliance a factor in selecting substitute parts?

A: The MAX495EPA is RoHS non-compliant. All three TLV2461 variants (TLV2461CP, TLV2461AIP, TLV2461IP) achieve ROHS3 compliance, making them suitable for applications subject to RoHS regulatory requirements.

Q: Which substitute part should be selected for applications operating below 0°C?

A: Applications requiring operation below 0°C must use either TLV2461AIP or TLV2461IP, both rated to -40°C minimum. TLV2461CP is limited to 0°C minimum and is unsuitable for sub-zero thermal environments.

Q: Are there any pinout differences between MAX495EPA and TLV2461 series devices?

A: No pinout differences exist. Both the MAX495EPA and all TLV2461 variants use identical 8-DIP package pinouts, enabling direct functional replacement without circuit redesign.
