LMV824DGVR Equivalent & Substitute Parts

Part Overview

The LMV824DGVR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TVSOP surface mount package. This device is classified as Obsolete and is no longer in active production. The LMV824DGVR delivers rail-to-rail output capability with a gain bandwidth product of 5.5 MHz, making it suitable for low-power analog signal processing applications requiring supply voltages between 2.5 V and 5.5 V.

Due to its obsolete status, locating replacement units from standard distribution channels becomes increasingly difficult. Active substitute parts maintain functional equivalence while offering improved availability and current product support from the manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMV824DGVR is determined by strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 4
• Output Type: Rail-to-Rail
• Supply Voltage Range: 2.5 V to 5.5 V
• Operating Temperature Range: -40°C to 85°C
• Input Bias Current: 40 nA
• Input Offset Voltage: 1 mV
• Output Current per Channel: 45 mA

Package Compatibility: The LMV824DGVR uses a 14-TFSOP package. Substitute parts must maintain the same pin count (14 pins) and footprint dimensions (0.173", 4.40mm Width) to ensure direct board-level compatibility.

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

The substitute parts listed below meet all functional and mechanical requirements while offering improved product status and availability.

Engineering Selection Recommendations

LMV824MT/NOPB is the manufacturer-recommended substitute for the obsolete LMV824DGVR. This part maintains active product status with Texas Instruments, ensuring continued technical support and long-term availability. The LMV824MT/NOPB is supplied in Tube packaging and demonstrates improved electrical performance with a slew rate of 2 V/µs and gain bandwidth product of 5.6 MHz compared to the main part specifications. All functional parameters, supply voltage ranges, and operating temperature specifications remain equivalent. ROHS3 compliance and MSL Level 1 rating are maintained.

LMV824MTX/NOPB provides an alternative substitute with identical electrical specifications and active product status. This variant is supplied in Cut Tape (CT) and Digi-Reel® format, offering higher inventory availability (35,400 units) compared to the Tube-packaged variant. Selection between LMV824MT/NOPB and LMV824MTX/NOPB depends on procurement requirements and tape-and-reel handling capabilities in manufacturing operations.

Both substitute parts are functionally interchangeable with the LMV824DGVR at the circuit level. Package differences (14-TFSOP versus 14-TSSOP) require PCB layout verification to confirm footprint compatibility, as both packages maintain identical pin counts and similar dimensional specifications (0.173", 4.40mm Width).

Frequently Asked Questions (FAQ)

Q: Can LMV824MT/NOPB or LMV824MTX/NOPB be used as direct replacements for LMV824DGVR on existing PCBs?

A: Both substitute parts maintain functional equivalence across all critical electrical parameters. However, the package designation changes from 14-TFSOP to 14-TSSOP. While both packages share the same pin count and similar dimensions (0.173", 4.40mm Width), PCB footprint verification is required before implementation. Consult the respective datasheets to confirm pad layout compatibility with your existing design.

Q: What is the difference between LMV824MT/NOPB and LMV824MTX/NOPB?

A: Both parts are electrically identical and share the same 14-TSSOP package. The primary difference is packaging format: LMV824MT/NOPB is supplied in Tube packaging, while LMV824MTX/NOPB is supplied in Cut Tape (CT) and Digi-Reel® format. Selection depends on your manufacturing process and component handling requirements. LMV824MTX/NOPB offers higher current inventory availability.

Q: Why are the slew rate and gain bandwidth product slightly higher in the substitute parts?

A: The substitute parts (LMV824MT/NOPB and LMV824MTX/NOPB) demonstrate improved electrical performance with slew rate of 2 V/µs and gain bandwidth product of 5.6 MHz compared to the main part's 1.9 V/µs and 5.5 MHz. These improvements represent manufacturing enhancements within the LMV824 series and do not affect functional compatibility. Both specifications remain within acceptable ranges for general-purpose amplifier applications.

Q: Are all three parts ROHS3 compliant and suitable for regulated procurement environments?

A: Yes. The LMV824DGVR, LMV824MT/NOPB, and LMV824MTX/NOPB are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status. All parts satisfy environmental and regulatory requirements for commercial and industrial applications.

Q: What is the primary reason to transition from LMV824DGVR to an active substitute?

A: The LMV824DGVR is classified as Obsolete and is no longer in active production. The substitute parts LMV824MT/NOPB and LMV824MTX/NOPB maintain Active product status with Texas Instruments, ensuring continued availability, technical support, and long-term supply chain reliability. Transitioning to active parts reduces obsolescence risk in future production cycles.
