TLV2332IDR Equivalent & Substitute Parts

Part Overview

The TLV2332IDR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring two independent circuits in an 8-SOIC surface mount package. This device operates across a 2V to 8V supply range and is designed for low-power applications requiring dual-channel amplification. The TLV2332IDR carries a Last Time Buy product status, indicating that this component is no longer in active production. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this device.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2332IDR is determined by compatibility across the following critical parameters:

Package and Pinout Compatibility: Both the main part and substitute must utilize the 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm width) to ensure direct board-level replacement without layout modifications.

Functional Architecture: The substitute must provide dual-channel (2 circuit) general-purpose amplification to maintain functional equivalence within the application.

Supply Voltage Range: The substitute must operate within or encompass the TLV2332IDR supply range of 2V to 8V. Substitutes with extended supply ranges remain compatible provided the minimum and maximum voltages support the original operating window.

Operating Temperature Range: The substitute must support the -40°C to 85°C operating temperature specification of the original device.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and REACH unaffected status to satisfy environmental and regulatory requirements.

The OPA2990IDR meets all substitution criteria through identical package geometry, dual-channel architecture, overlapping supply voltage compatibility, and equivalent regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The OPA2990IDR is the manufacturer-recommended substitute for the TLV2332IDR. Both devices are manufactured by Texas Instruments and maintain identical 8-SOIC package geometry, enabling direct board-level substitution without PCB layout modifications.

Regulatory and Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent applications.

Product Status Consideration: The TLV2332IDR carries Last Time Buy status, indicating discontinued production. The OPA2990IDR maintains Active product status, ensuring long-term availability and supply chain continuity for new designs and production requirements.

Supply Voltage Compatibility: The OPA2990IDR operates across a 2.7V to 40V supply range, which encompasses the TLV2332IDR operating window of 2V to 8V. Applications designed for the original 2V to 8V range operate within the substitute's specified parameters.

Operating Temperature Range: The OPA2990IDR supports -40°C to 125°C operation, extending the upper temperature limit beyond the TLV2332IDR specification of -40°C to 85°C. This provides enhanced thermal margin for demanding applications.

Performance Characteristics: The OPA2990IDR delivers improved performance metrics including higher slew rate (4.5V/µs versus 0.43V/µs), increased gain bandwidth product (1.1MHz versus 525kHz), lower input bias current (10pA versus 0.6pA), and higher output current capability (80mA versus 30mA per channel). These enhancements support applications requiring faster signal processing and greater output drive capability.

Frequently Asked Questions (FAQ)

Q: Can the OPA2990IDR directly replace the TLV2332IDR without PCB modifications?

A: Yes. Both devices utilize identical 8-SOIC surface mount packages with matching pinout and physical dimensions (0.154", 3.90mm width). Direct board-level substitution is possible without layout changes.

Q: What is the minimum supply voltage for the OPA2990IDR when replacing a TLV2332IDR?

A: The OPA2990IDR minimum supply voltage is 2.7V, compared to the TLV2332IDR minimum of 2V. Applications operating at exactly 2V require verification that the OPA2990IDR minimum specification is acceptable for the circuit design.

Q: Does the OPA2990IDR maintain the same regulatory compliance as the TLV2332IDR?

A: Yes. Both devices are ROHS3 compliant and REACH unaffected, maintaining equivalent environmental and regulatory compliance.

Q: Why does the OPA2990IDR have higher performance specifications than the TLV2332IDR?

A: The OPA2990IDR is an active production device with enhanced performance characteristics including rail-to-rail output capability, higher slew rate, increased bandwidth, and greater output current. These improvements reflect advances in operational amplifier design while maintaining package and functional compatibility.

Q: Is the OPA2990IDR suitable for low-power applications designed for the TLV2332IDR?

A: The OPA2990IDR supply current is 130µA (x2 channels) compared to the TLV2332IDR at 210µA (x2 channels), representing a 38% reduction in power consumption. The substitute is suitable for low-power applications and provides improved power efficiency.

Q: What is the product status difference between these two devices?

A: The TLV2332IDR carries Last Time Buy status, indicating production discontinuation. The OPA2990IDR maintains Active status, ensuring ongoing availability for new designs and continued production support.
