LM358DMR2 Equivalent & Substitute Parts

Part Overview

The LM358DMR2 is a general-purpose operational amplifier featuring two independent circuits in an 8-MSOP surface mount package. This device is classified as obsolete and operates across a supply voltage range of 3V to 32V with a gain bandwidth product of 1 MHz. The LM358DMR2 is no longer in active production, making equivalent and substitute parts necessary for new designs and ongoing production requirements. Alternative components with matching or superior electrical characteristics and compatible packaging are available from multiple manufacturers.

Substitute Part Grouping Explanation

Substitution of the LM358DMR2 is determined by the following critical parameters: amplifier type (general purpose), number of circuits (2), package compatibility (8-MSOP or 8-TSSOP), supply voltage range (minimum 3V, maximum 32V), and output current capability (40 mA per channel). Parts are grouped into two categories:

Direct Equivalents: Parts with identical electrical specifications and compatible packaging, differing only in product status or packaging format (tape & reel versus bulk).

Functional Alternatives: Parts with superior or equivalent electrical performance in key parameters (gain bandwidth product, slew rate, input bias current, input offset voltage) that maintain compatibility with the 8-MSOP/8-TSSOP package footprint and supply voltage requirements.

The LM358DMR2 is RoHS non-compliant. Substitute parts meeting RoHS3 compliance are available for applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can LM358DMR2G be used as a direct replacement for LM358DMR2?

A: Yes. LM358DMR2G is electrically identical to LM358DMR2 with matching gain bandwidth product (1 MHz), input bias current (45 nA), input offset voltage (2 mV), supply current (800µA per channel pair), and output current capability (40 mA per channel). Both use 8-MSOP packaging. LM358DMR2G is active and RoHS3 compliant, whereas LM358DMR2 is obsolete and RoHS non-compliant.

Q: What is the primary difference between general purpose and J-FET amplifier substitutes?

A: General purpose amplifiers (LM358 variants, AS358, BA3404, BA3472) use bipolar input stages with input bias currents in the nanoampere range (20-100 nA). J-FET amplifiers (ADA4062-2, ADTL082) use field-effect transistor input stages with input bias currents in the picoampere range (2 pA), providing superior input impedance and lower input bias current. J-FET alternatives require higher minimum supply voltages (8V versus 3V).

Q: Are all substitute parts compatible with the 8-MSOP package footprint?

A: All listed substitute parts are compatible with 8-MSOP or 8-TSSOP package footprints with 0.118" (3.00mm) width. BA3404FVM-TR and BA3472RFVM-TR use 8-VSSOP packaging with 0.110" (2.80mm) width, which is mechanically compatible with 8-MSOP footprints but has slightly different dimensions.

Q: Which substitute parts are RoHS3 compliant?

A: LM358DMR2G, LM358DGKR, AS358MMTR-G1, BA3404FVM-TR, BA3472RFVM-TR, ADA4062-2ARMZ, ADA4062-2ARMZ-R7, ADA4062-2ARMZ-RL, ADTL082ARMZ, and ADTL082ARMZ-REEL are all RoHS3 compliant. LM358DMR2 is RoHS non-compliant.

Q: What is the minimum supply voltage requirement for J-FET alternatives?

A: J-FET alternatives (ADA4062-2 series and ADTL082 series) require a minimum supply voltage of 8V, compared to 3V for the LM358DMR2 and general purpose alternatives. Applications operating at supply voltages below 8V cannot use J-FET substitutes.

Q: How do output current capabilities compare across substitute options?

A: LM358DMR2, LM358DMR2G, LM358DGKR, and AS358MMTR-G1 provide 40 mA output current per channel. BA3404FVM-TR and BA3472RFVM-TR provide 30 mA per channel. ADA4062-2 series provides 20 mA per channel. ADTL082 series provides 27 mA per channel. Applications requiring 40 mA output current must use LM358 or AS358 variants.

Q: Which substitute offers the widest operating temperature range?

A: BA3472RFVM-TR and ADTL082 series (ADTL082ARMZ and ADTL082ARMZ-REEL) offer the widest operating temperature range at -40°C to 105°C and -40°C to 125°C respectively, compared to LM358DMR2 at 0°C to 70°C.

Q: What are the packaging format options for substitute parts?

A: Packaging formats include bulk (LM358DMR2), tape & reel (LM358DMR2G, ADA4062-2ARMZ-R7, ADA4062-2ARMZ-RL, AS358MMTR-G1), tube (ADA4062-2ARMZ, ADTL082ARMZ), and cut tape with Digi-Reel (BA3404FVM-TR, BA3472RFVM-TR, ADTL082ARMZ-REEL). Selection depends on production volume and assembly requirements.

Q: Can BA3404FVM-TR or BA3472RFVM-TR be used in applications requiring 40 mA output current per channel?

A: No. BA3404FVM-TR and BA3472RFVM-TR provide only 30 mA output current per channel, which is insufficient for applications requiring 40 mA. LM358DMR2G, LM358DGKR, or AS358MMTR-G1 must be used for 40 mA output current requirements.

Q: What is the significance of push-pull output configuration in BA3404FVM-TR?

A: Push-pull output configuration in BA3404FVM-TR provides improved output impedance characteristics and higher output current capability in both sourcing and sinking directions compared to standard open-collector or open-drain configurations. This is beneficial for driving capacitive loads and reducing output impedance.
