L2720 Equivalent & Substitute Parts

Part Overview

The STMicroelectronics L2720 is a general purpose operational amplifier integrated circuit containing 2 amplifier circuits in a 16-PowerDIP through-hole package. This device is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

The L2720 operates across a wide supply voltage range of 4V to 28V and is suitable for general purpose amplification applications requiring moderate bandwidth and output current capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L2720 is determined by the following critical parameters:

Functional Requirements:

• Number of circuits: 2 amplifier circuits required
• Amplifier classification: General purpose or power amplifier topology
• Gain bandwidth product: Minimum 1.2 MHz
• Output current capability: Minimum 1 A per channel

Electrical Compatibility:

• Supply voltage range: Minimum 4V to 28V overlap required
• Operating temperature: Minimum -40°C to 85°C coverage
• Input bias current and offset voltage within acceptable application tolerances

Physical & Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required
• Through-hole or surface-mount package acceptable based on board design

The onsemi TCA0372DWR2G qualifies as a substitute based on matching circuit count, exceeding bandwidth specifications, maintaining supply voltage compatibility, and providing superior temperature range coverage while maintaining all required compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The L2720 is classified as obsolete. The TCA0372DWR2G is classified as active, ensuring continued availability and manufacturing support for future procurement requirements.

Compliance & Certification: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution in compliant applications.

Supply Voltage Compatibility: The TCA0372DWR2G operates at a minimum supply voltage of 5V, compared to the L2720 minimum of 4V. Applications requiring operation below 5V require verification of actual circuit supply voltage before substitution.

Temperature Range: The TCA0372DWR2G provides extended operating temperature coverage to 125°C, exceeding the L2720 specification of 85°C. This represents an improvement for applications requiring higher temperature operation.

Output Current: The L2720 provides 1.5A per channel output current, while the TCA0372DWR2G provides 1A per channel. Applications requiring output current exceeding 1A per channel require circuit redesign or alternative component selection.

Package Transition: The L2720 uses through-hole 16-PowerDIP packaging, while the TCA0372DWR2G uses surface-mount 16-SOIC packaging. Board redesign is required for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TCA0372DWR2G directly replace the L2720 in existing PCB designs?

A: No. The L2720 uses through-hole 16-PowerDIP packaging while the TCA0372DWR2G uses surface-mount 16-SOIC packaging. PCB redesign is required for mechanical compatibility. Pin-to-pin electrical compatibility must be verified against specific application schematics.

Q: What is the minimum supply voltage difference between these components?

A: The L2720 operates at a minimum of 4V, while the TCA0372DWR2G operates at a minimum of 5V. Applications with supply voltages between 4V and 5V cannot use the TCA0372DWR2G as a substitute.

Q: Does the TCA0372DWR2G provide equivalent output current capability?

A: No. The L2720 provides 1.5A per channel output current, while the TCA0372DWR2G provides 1A per channel. Applications requiring output current exceeding 1A per channel must use the L2720 or select an alternative component with higher output current rating.

Q: Are both components RoHS compliant?

A: Yes. Both the L2720 and TCA0372DWR2G are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for equivalent substitution in compliant applications.

Q: What is the primary advantage of the TCA0372DWR2G over the L2720?

A: The TCA0372DWR2G is an active product with continued manufacturing support, compared to the obsolete L2720. Additionally, the TCA0372DWR2G provides extended operating temperature range to 125°C and improved input offset voltage specification of 1mV versus 10mV.

Q: Can the L2720 be used in applications designed for the TCA0372DWR2G?

A: Substitution in reverse is not recommended. The L2720 is obsolete and may have limited availability. New designs should use active components such as the TCA0372DWR2G.

Q: What packaging options are available for the TCA0372DWR2G?

A: The TCA0372DWR2G is supplied in Cut Tape (CT) and Digi-Reel packaging formats in 16-SOIC surface-mount configuration.
