Product details
Overview
LMV358LIDT from STMicroelectronics is a dual rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 1.3 MHz gain bandwidth, 250 µA max supply current per channel at 5 V, and operates across -40 °C to +125 °C. Used in portable medical sensors and battery-powered signal conditioning circuits where space and power efficiency are critical.
For engineers reviewing the LMV358LIDT datasheet, LMV358LIDT pinout, LMV358LIDT application, or LMV358LIDT equivalent, key selection criteria include rail-to-rail output swing (≤180 mV from rails), input common-mode range extending to ground, industrial temperature rating, and SO8 package compatibility with legacy PCB footprints.
Technical Context
The LMV358LIDT implements a CMOS input stage enabling rail-to-rail input common-mode operation down to VCC− − 0.2 V and up to VCC+ − 1 V, with no phase reversal. Its output stage supports rail-to-rail swing into 10 kΩ loads, delivering 4.90 V high-level and 65 mV low-level output at 5 V supply.
Internally compensated for unity-gain stability with 60° phase margin and 10 dB gain margin at 200 pF capacitive load, it maintains stable operation in active filtering and sensor buffering without external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct use with single-cell Li-ion (3.0–3.7 V) and 3.3 V/5 V logic rails |
| Gain Bandwidth Product | 1.3 MHz - supports audio-band signal conditioning and anti-aliasing filters up to ~100 kHz |
| Input Offset Voltage | 7 mV max at 25 °C - sufficient for non-precision DC-coupled amplification in portable instrumentation |
| Supply Current per Channel | 250 µA max at 5 V - allows two op-amps to consume <500 µA total, ideal for multi-day battery life |
| Operating Temperature Range | −40 °C to +125 °C - qualified for under-hood automotive sensors and industrial field devices |
| Rail-to-Rail Output Swing | ≤180 mV from supply rails at 10 kΩ - preserves dynamic range in low-voltage systems without level-shifting circuitry |
| Input Common-Mode Range | VCC− − 0.2 V to VCC+ − 1 V - accepts signals referenced to ground in single-supply configurations |

| 2 | IN1− | Inverting input of first channel - used for closed-loop gain setting or differential sensing |
| 3 | IN1+ | Non-inverting input of first channel - accepts single-ended sensor signals referenced to ground |
| 4 | VCC− | Negative supply pin - connected to system ground in single-supply operation |
| 5 | IN2+ | Non-inverting input of second channel - enables dual-sensor monitoring on one IC |
| 6 | IN2− | Inverting input of second channel - supports independent gain configuration per channel |
| 7 | OUT2 | Output of second op-amp channel - provides redundancy or parallel signal path |
| 8 | VCC+ | Positive supply pin - accepts 2.7–5.5 V; requires local 10 nF decoupling per datasheet recommendation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Higher 2.4 MHz GBP but 550 µA/channel supply current; 10 µV/°C offset drift vs. LMV358LIDT's 5 µV/°C | Better for higher-frequency filtering but less suitable for ultra-low-power battery operation | Select when bandwidth >1.3 MHz is required and power budget allows ≥2× current draw |
| MCP6022-I/SN | Lower 3 mV max offset but narrower 2.7–6.0 V supply range; not rated beyond +85 °C | Preferred for precision DC amplification in commercial-grade equipment only | Choose for improved DC accuracy in non-automotive, non-industrial environments with relaxed temp requirements |
Compared with TLV2372IDR and MCP6022-I/SN, LMV358LIDT offers the optimal balance of industrial temperature rating, ultra-low quiescent current, and SO8 compatibility-making it uniquely suited for cost-sensitive, battery-powered industrial and medical edge devices where long-term reliability trumps marginal AC performance gains.

FAQ
Is LMV358LIDT pin-compatible with standard LM358 SO8 packages?
Yes, LMV358LIDT uses the same SO8 footprint and pinout as industry-standard LM358 variants, including identical VCC+, OUT1, IN1−, IN1+, VCC−, IN2+, IN2−, and OUT2 assignments. No PCB layout changes are needed for drop-in replacement, though decoupling capacitor placement should follow ST's 10 nF recommendation near pins 4 and 8.
What is the maximum capacitive load the LMV358LIDT can drive without instability?
LMV358LIDT remains stable with up to 200 pF capacitive load at unity gain, maintaining ≥60° phase margin per datasheet Figure 9. For loads exceeding 200 pF, a series resistor (≥100 Ω) between the output and capacitive node is recommended to isolate the pole and preserve stability in active filter or cable-driving applications.
Does LMV358LIDT support true rail-to-rail input operation?
No - LMV358LIDT features rail-to-rail *output*, but its input common-mode range extends from VCC− − 0.2 V to VCC+ − 1 V. This allows ground-referenced inputs in single-supply use but does not include the positive rail. For true rail-to-rail input, consider ST's TSX922IYDT or similar CMOS-input alternatives.
Can LMV358LIDT operate reliably at 2.7 V supply with full specification?
Yes - all key parameters including gain bandwidth (1.3 MHz), input offset voltage (7 mV max), and output swing (≤180 mV from rails) are fully specified and tested at 2.7 V. Electrical characteristics tables explicitly confirm performance across 2.7 V and 5 V supplies, making it suitable for end-of-life battery operation in 3 V systems.
