Product details
Overview
LMV358QD from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage single-supply operation (2.7 V to 5.5 V), delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in portable media players, HVAC sensor conditioning, and motor control feedback loops.
For engineers reviewing the LMV358QD datasheet, LMV358QD pinout, LMV358QD application, or LMV358QD equivalent, key selection criteria include rail-to-rail output swing down to 60 mV from rails at 10 kΩ load, input offset voltage of 1.7–7 mV, –40°C to 125°C operating temperature range, and SOIC-8 package compatibility with legacy LM358 footprints.
Technical Context
The LMV358QD implements a CMOS input stage with rail-to-rail output stage using complementary push-pull drivers, enabling full-swing operation from VCC to GND. Its internal architecture supports common-mode input voltage down to ground (VICR = 0 V) and up to VCC – 0.2 V at 2.7 V supply.
It operates as a dual-channel general-purpose op-amp without shutdown functionality (unlike LMV324S), with independent amplifiers sharing only power and ground rails. Each channel exhibits identical AC/DC specifications including 63 dB typical CMRR and 60 dB typical PSRR at 2.7 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - supports stable closed-loop gain ≥1 up to audio frequencies with minimal phase lag. |
| Slew Rate | 1 V/μs - limits large-signal settling time to ≤1 μs for 1 V step, suitable for medium-speed signal conditioning. |
| Input Offset Voltage | 1.7–7 mV (typ) - determines DC error in precision gain stages; requires <10 mV error budget in sensor interfaces. |
| Rail-to-Rail Output Swing | 60–180 mV from rails (10 kΩ load) - delivers >95% of full supply range for ADC driver and comparator reference applications. |
| Supply Current per Channel | 210 μA (typ at 2.7 V) - allows dual-amplifier operation within 500 μA total budget for battery-powered devices. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial motor control environments. |
Pinout & Package
LMV358QD is packaged in an 8-pin SOIC (D) package measuring 4.90 mm × 3.91 mm × 1.75 mm, with standard JEDEC MS-012AC footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Output of Amplifier 1 | Delivers rail-to-rail buffered or amplified signal; drives loads ≥10 kΩ directly. |
| 1IN– | Inverting Input of Amplifier 1 | Accepts feedback network or inverted signal path; high-impedance CMOS node (IIB = 11–250 nA). |
| 1IN+ | Noninverting Input of Amplifier 1 | Accepts reference, sensor, or signal source; supports common-mode range to GND. |
| GND | Negative Supply Reference | System ground return for both amplifiers; must be low-impedance to minimize noise coupling. |
| VCC+ | Positive Supply Rail | Single 2.7–5.5 V supply input; decoupling capacitor (0.1 μF) required adjacent to pin. |
| 2OUT | Output of Amplifier 2 | Independent output channel; electrically isolated from 1OUT except via shared supply rails. |
| 2IN– | Inverting Input of Amplifier 2 | Functionally identical to 1IN–; supports separate feedback configuration per channel. |
| 2IN+ | Noninverting Input of Amplifier 2 | Functionally identical to 1IN+; enables dual-path signal processing on one die. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Enables full utilization of ADC input range in 3.3 V systems without external level-shifting circuitry. |
| Ground-sensing input stage | Allows direct interfacing with 0 V-referenced sensors (e.g., thermistors, bridge transducers) without biasing resistors. |
| Low 210 μA supply current per channel | Supports always-on sensor monitoring in energy-constrained IoT nodes with multi-year battery life. |
| 1 MHz bandwidth with 60° phase margin | Ensures stable unity-gain follower and non-inverting configurations without external compensation. |
| JESD22-A114 ESD rating: 2000 V HBM | Withstands handling and board-level ESD events in automated assembly and field service environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Wider supply range (3–30 V), no rail-to-rail output (min swing = 1.5 V from rails), higher ICC = 700 μA. | Requires ≥5 V supply; unsuitable for 3.3 V ADC drivers or battery-powered designs. | Select LM358DR only when legacy 5 V systems demand pin compatibility and rail-to-rail output is unnecessary. |
| TLV2372IDR | Lower ICC = 20 μA/ch, wider GBW = 2.4 MHz, but narrower VICR (0.2 V above GND) and lower drive capability. | Better for ultra-low-power sensor nodes; less robust driving 10 kΩ loads at full swing. | Choose TLV2372IDR when sub-50 μA total supply budget is critical and output loading is light (≥100 kΩ). |
Compared with LM358DR and TLV2372IDR, LMV358QD uniquely balances rail-to-rail output, 210 μA supply current, and –40°C to 125°C operation - making it optimal for cost-sensitive industrial and appliance designs needing full 3.3 V dynamic range without layout redesign.

FAQ
What is the maximum operating supply voltage for LMV358QD?
The absolute maximum supply voltage for LMV358QD is 5.5 V, as specified in Section 7.1 Absolute Maximum Ratings. Operation beyond this voltage risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full electrical performance guaranteed across that span per Section 7.3.
Does LMV358QD support true rail-to-rail input?
No, LMV358QD does not support rail-to-rail input. Its common-mode input voltage range extends to GND (0 V) but only up to VCC – 0.2 V at 2.7 V supply, per Section 7.5. It is a rail-to-rail *output* amplifier, not rail-to-rail input - meaning inputs cannot safely reach VCC.
What is the typical input offset voltage of LMV358QD at 25°C and 2.7 V supply?
The typical input offset voltage of LMV358QD is 7 mV at 25°C and 2.7 V supply, with a minimum of 1.7 mV and maximum of 9 mV across the full temperature range (–40°C to 125°C), as documented in Section 7.5 Electrical Characteristics.
Can LMV358QD drive a 2 kΩ load while maintaining rail-to-rail output swing?
No - at RL = 2 kΩ, LMV358QD's output swing degrades to VCC – 300 mV (high) and 120 mV (low) at 5 V supply (Section 7.6). For full rail-to-rail behavior, load impedance must be ≥10 kΩ. At 2 kΩ, headroom loss exceeds 300 mV, limiting usable dynamic range.
Is LMV358QD pin-compatible with standard LM358 packages?
Yes, LMV358QD in SOIC-8 (D) package is pin-compatible with LM358DR and LM358N in the same SOIC-8 outline. Pin functions match exactly: 1OUT, 1IN–, 1IN+, GND, VCC+, 2OUT, 2IN–, 2IN+. However, LMV358QD offers rail-to-rail output and lower supply current - enhancements that do not affect footprint or connectivity.
