LMV822DG4 Equivalent & Substitute Parts

Part Overview

The LMV822DG4 is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) rail-to-rail output device in an 8-SOIC surface mount package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement.

The LMV822DG4 operates across a supply voltage range of 2.5 V to 5.5 V with an operating temperature range of -40°C to 85°C. It delivers a slew rate of 1.9 V/µs, gain bandwidth product of 5.5 MHz, and output current per channel of 45 mA. The part is RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level).

Due to its obsolete status, substitute parts with equivalent or superior electrical characteristics and identical mechanical compatibility are required for new designs and production continuity.

Engineering Selection Recommendations

Direct Replacement (Highest Compatibility):

LMV822M/NOPB and LMV822MX/NOPB are direct active replacements for the obsolete LMV822DG4. Both parts are manufactured by Texas Instruments, share the identical base product number (LMV822), and maintain electrical specifications within 5% of the original part. These variants differ only in packaging format (Tube vs. Cut Tape & Digi-Reel®) and are available in high inventory quantities. Both are RoHS3 compliant with MSL 1 rating and are suitable for drop-in replacement without circuit redesign.

Automotive-Grade Alternative:

LMV822AIDT and LMV822IDT, manufactured by STMicroelectronics, provide automotive-grade qualification (AEC-Q100) with extended operating temperature range (-40°C to 125°C). These parts maintain the core electrical specifications of the original LMV822DG4 while offering improved temperature performance and automotive reliability standards. The LMV822AIDT variant is available in higher inventory (25,200 units) compared to LMV822IDT (17,900 units).

Enhanced Performance Alternative:

LMV722M/NOPB and LMV722MX/NOPB offer superior performance characteristics with 5.25 V/µs slew rate and 10 MHz gain bandwidth product, representing an 81% improvement in bandwidth. These parts maintain supply voltage compatibility (2.2 V to 5.5 V minimum) and are suitable for applications requiring higher-speed operation. Both are active products with substantial inventory availability.

CMOS Technology Alternative:

AD8602ARZ-REEL provides CMOS amplifier technology with extremely low input bias current (0.2 pA) and extended operating temperature range (-40°C to 125°C). This part is suitable for applications requiring ultra-low input bias current and higher temperature operation, though it exhibits higher supply current consumption (750 µA vs. 500 µA).

General-Purpose Alternative:

MAX4326ESA+T offers rail-to-rail operation with extended supply voltage range (2.4 V to 6.5 V maximum) and is suitable for applications requiring wider supply voltage tolerance. This part maintains comparable slew rate and bandwidth characteristics to the original LMV822DG4.

Low-Power Alternative:

MCP617-I/SN and MCP617T-I/SN are CMOS amplifiers with ultra-low supply current (19 µA) suitable for battery-powered applications. These parts are not recommended as direct replacements due to significantly reduced slew rate (0.08 V/µs) and gain bandwidth product (190 kHz), which fall below the original part specifications. Selection of these parts requires circuit redesign and performance verification.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between LMV822M/NOPB and LMV822MX/NOPB?

A: Both parts are electrically identical. The difference is packaging format: LMV822M/NOPB is supplied in Tube packaging, while LMV822MX/NOPB is supplied in Cut Tape & Digi-Reel® format. LMV822MX/NOPB has higher inventory availability (30,163 units vs. 2,155 units).

Q: Why are MCP617 series parts listed as substitutes if they have lower performance?

A: MCP617-I/SN and MCP617T-I/SN are included as functional alternatives for applications where ultra-low supply current is the primary design requirement. These parts are not suitable for applications requiring the original slew rate (1.9 V/µs) or bandwidth (5.5 MHz) specifications. Selection requires circuit redesign and performance validation.

Q: Are STMicroelectronics LMV822AIDT and LMV822IDT suitable for automotive applications?

A: Yes. Both parts carry AEC-Q100 automotive qualification and extended operating temperature range (-40°C to 125°C). These parts are suitable for automotive and industrial applications requiring higher temperature operation than the original LMV822DG4 (-40°C to 85°C).

Q: What is the advantage of LMV722M/NOPB over LMV822M/NOPB?

A: LMV722M/NOPB offers superior performance with 5.25 V/µs slew rate (vs. 2.0 V/µs) and 10 MHz gain bandwidth product (vs. 5.6 MHz). This part is suitable for applications requiring higher-speed signal processing. The trade-off is higher supply current consumption (2.01 mA vs. 500 µA) and higher input bias current (260 nA vs. 40 nA).

Q: Is the 8-SOIC package identical across all substitute parts?

A: Yes. All substitute parts listed use the 8-SOIC package with 0.154" (3.90mm) width. Pin assignments and footprints are compatible for direct PCB substitution. Verify pinout compatibility with the original LMV822DG4 datasheet before assembly.

Q: Can AD8602ARZ-REEL be used in place of LMV822DG4 without circuit changes?

A: AD8602ARZ-REEL is pin-compatible and package-compatible but uses CMOS technology with different electrical characteristics. The extremely low input bias current (0.2 pA) and higher slew rate (6.0 V/µs) may affect circuit behavior in applications sensitive to input impedance or bandwidth. Circuit validation is required.

Q: What is the moisture sensitivity level (MSL) for all substitute parts?

A: All substitute parts listed carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage and handling requirements are identical to the original LMV822DG4.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which substitute part has the highest inventory availability?

A: LMV822MX/NOPB has the highest inventory availability at 30,163 units in stock, followed by LMV722MX/NOPB at 35,400 units. Both are suitable for immediate procurement.
