Texas Instruments LMV358Q1MMX/NOPB

Overview

LMV358Q1MMX/NOPB from Texas Instruments is a dual, rail-to-rail output operational amplifier designed for low-voltage (2.7 V to 5.5 V), single-supply industrial and automotive applications. It delivers 1 MHz gain-bandwidth product, 1 V/µs slew rate, 210 µA supply current per amplifier, −0.2 V to 4.0 V input common-mode range, and rail-to-rail output swing (V₊−10 mV / V₋+65 mV at 10 kΩ) - enabling precision signal conditioning in battery-powered sensor interfaces and motor control feedback loops.

For engineers reviewing the LMV358Q1MMX/NOPB datasheet, LMV358Q1MMX/NOPB pinout, LMV358Q1MMX/NOPB application, or LMV358Q1MMX/NOPB equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, guaranteed 2.7-V operation, no crossover distortion, −40°C to +125°C temperature range, and SOIC-8 packaging with validated thermal resistance (R_θJA = 207.9°C/W).

Technical Context

The LMV358Q1MMX/NOPB implements a bipolar-input, rail-to-rail output architecture optimized for low-voltage DC-coupled amplification and active filtering. Its input stage includes ground-sensing capability (V_CM down to −0.2 V), while the output stage achieves full swing within 10 mV of V₊ and 65 mV of V₋ under 10-kΩ load - critical for maximizing dynamic range in 3.3-V and 5-V systems.

It operates across 2.7 V–5.5 V supply rails with guaranteed performance at both endpoints, exhibits 50 dB minimum CMRR and PSRR over 0 V–4 V common-mode range, and maintains stable unity-gain operation with up to 200 pF capacitive load - eliminating need for external compensation in most sensor buffer and DAC output driver configurations.

FAQ

What is the maximum capacitive load LMV358Q1MMX/NOPB can drive without oscillation?

The LMV358Q1MMX/NOPB is stable with up to 200 pF capacitive load in unity-gain configuration, as verified in TI's SNOS012K datasheet Figure 7-23. This eliminates need for external isolation resistors when interfacing directly to typical 12-bit and 16-bit SAR ADC inputs, which commonly present 10–50 pF capacitance. For loads exceeding 200 pF, a series resistor (e.g., 620 Ω) between amplifier output and capacitor restores phase margin.

Does LMV358Q1MMX/NOPB support true single-supply operation with input signals at ground potential?

Yes, LMV358Q1MMX/NOPB supports true single-supply operation with input common-mode voltage down to −0.2 V, allowing direct connection to ground-referenced sensors such as NTC thermistors, current-shunt amplifiers, and bridge transducers. The input stage includes ESD protection diodes; however, input voltages must not fall below −0.3 V to avoid forward-biasing internal clamps and causing excessive current.

What is the thermal performance of LMV358Q1MMX/NOPB in SOIC-8 package?

LMV358Q1MMX/NOPB in SOIC-8 (package code D) has a junction-to-ambient thermal resistance (R_θJA) of 207.9°C/W when mounted on a standard 1-in² 2-oz copper PCB, per TI SNOS012K Section 7.6. At 420 µA total supply current (210 µA per amplifier) and 5-V supply, power dissipation is ~2.1 mW - resulting in <0.5°C junction rise above ambient, confirming suitability for thermally constrained automotive modules.

How does LMV358Q1MMX/NOPB eliminate crossover distortion compared to legacy LM358?

LMV358Q1MMX/NOPB uses an enhanced bipolar output stage that eliminates the dead zone around zero crossing present in LM358. As shown in TI SNOS012K Figure 8-1, this results in continuous, glitch-free output transitions - critical for audio preamplifiers, precision comparators, and closed-loop control systems where zero-crossing errors cause instability or audible artifacts.

Is LMV358Q1MMX/NOPB pin-compatible with standard LM358 variants?

Yes, LMV358Q1MMX/NOPB uses the industry-standard SOIC-8 pinout (pin 1 = OUT A, pin 2 = IN− A, pin 3 = IN+ A, pin 4 = V−, pin 5 = IN+ B, pin 6 = IN− B, pin 7 = OUT B, pin 8 = V+), matching LM358, LMV358-N, and LMV358M/NOPB. No PCB redesign is needed when upgrading from commercial to automotive-qualified dual op amps in existing layouts.
