Product details
Overview
LMV358IDT from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in SO8 package, operating from 2.7 V to 6 V supply, delivering 1 MHz gain bandwidth product, 145 µA per amplifier supply current, and ±3 mV input offset voltage at 25 °C. It serves as a low-power signal conditioning and buffering stage in portable medical devices and battery-powered instrumentation.
For engineers reviewing the LMV358IDT datasheet, LMV358IDT pinout, LMV358IDT application, or LMV358IDT equivalent, key selection criteria include rail-to-rail I/O swing at low supply voltage, thermal performance in SO8 (125 °C/W RthJA), output drive capability (±46 mA), and common-mode input range extended to VDD − 0.2 V at 25 °C.
Technical Context
The LMV358IDT integrates two independent high-precision op-amps with matched input bias currents (16–63 nA typ. at 5 V), enabling stable DC-coupled configurations. Its internal architecture supports rail-to-rail operation across full temperature range (−40 °C to +125 °C) when VCC ≤ 5.5 V, and features 85 dB CMRR and 90 dB SVRR at 5 V.
It delivers 0.45 V/µs slew rate into 600 Ω load with 100 pF capacitance, maintaining 48° phase margin for robust stability in unity-gain buffer and active filter applications. Input voltage noise is fixed at 40 nV/√Hz, and THD remains ≤0.01% under typical conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 6 V - enables direct use with single-cell Li-ion or dual-cell alkaline supplies |
| Gain Bandwidth Product | 1.3 MHz at 5 V - sufficient for sensor amplification and anti-aliasing filters up to ~100 kHz |
| Input Offset Voltage | ≤3 mV at 25 °C - ensures <100 µV error in 3.3 V full-scale 12-bit ADC front-end |
| Supply Current per Amp | 162 µA typ. at 5 V - allows dual-channel operation on <330 µA total, critical for multi-day battery life |
| Output Drive Current | ±48 mA - drives 10 kΩ loads to rail while sustaining >2.5 V swing at 5 V supply |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V at 25 °C - supports direct sensing of signals near ground or supply rails |
| ESD Rating (HBM) | 2 kV - meets IEC 61000-4-2 Level 2 for handheld device interface protection |
Pinout & Package
LMV358IDT is housed in an 8-pin SOIC (SO8) package with standard JEDEC MS-012AC footprint, 1.27 mm pitch, and 5.0 mm × 6.2 mm body size. Thermal resistance junction-to-ambient is 125 °C/W, supporting continuous operation at ambient up to 85 °C with no derating.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - rail-to-rail swing supports direct connection to SAR ADC reference or comparator input |
| 2 | Inverting Input A | High-impedance node (Iib = 16–63 nA) - requires <10 kΩ source impedance to limit offset error |
| 3 | Non-inverting Input A | Matches Pin 2 bias current - enables precision differential or instrumentation configurations |
| 4 | VDD (Ground) | Power return for both amplifiers - must be low-inductance path to minimize PSRR degradation |
| 5 | Non-inverting Input B | Independent input for second channel - electrically isolated from Channel A except shared supply pins |
| 6 | Inverting Input B | Matched to Pin 5 - allows dual-sensor conditioning with common-mode rejection across channels |
| 7 | Output B | Amplifier B output - identical AC/DC specs to Pin 1; usable for feedback loop or signal routing |
| 8 | VCC (Supply) | Positive supply for both amplifiers - accepts 2.7–6 V; bypass capacitor required within 5 mm |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems without level-shifting circuitry |
| Extended common-mode input range | VDD − 0.2 V to VCC + 0.2 V at 25 °C - supports direct measurement of 0 V-referenced transducer outputs |
| Low quiescent current | 145 µA per amplifier at 2.7 V - extends battery life in glucose meters and pulse oximeters beyond 100 hours |
| 1 MHz GBP with 0.45 V/µs slew rate | Stable unity-gain operation with 100 pF capacitive load - eliminates need for external compensation in sensor buffers |
| 85 dB CMRR at 5 V | Rejects power-supply ripple and EMI-induced common-mode noise in noisy embedded environments |
Applications
| Battery-Powered Glucose Meter | Portable ECG Front-End |

Use Scenario: Amplifying low-amplitude (1–10 mV), DC-coupled biosignals from enzymatic test strips under variable temperature and battery voltage. IC Role / Device Role / Timing Role: Dual-channel transducer signal conditioner - Channel A for reference electrode, Channel B for working electrode, both operating in single-supply 3.3 V mode. Use Value: Rail-to-rail I/O preserves full 12-bit ADC resolution; 145 µA per amp minimizes impact on coin-cell lifetime. |
Use Scenario: Buffering and filtering raw electrode signals prior to 24-bit delta-sigma ADC sampling at 1 kHz. IC Role / Device Role / Timing Role: First-stage instrumentation amplifier driver - provides high-Z input, low noise (40 nV/√Hz), and 85 dB CMRR to suppress 50/60 Hz interference. Use Value: Extended Vicm allows direct coupling to electrodes biased at 1.65 V, eliminating AC-coupling capacitors and associated drift. |

Use Scenario: Converting photodiode current (nA–µA range) into voltage for microcontroller ADC with minimal board space. IC Role / Device Role / Timing Role: Transimpedance amplifier (TIA) with programmable gain - uses Channel A for TIA, Channel B for reference voltage generation. Use Value: Low input bias current (16 nA typ.) prevents photodiode leakage from dominating signal; SO8 footprint fits tight layout constraints. |
Use Scenario: Conditioning PT100 bridge output (≈100–200 mV) in 4–20 mA loop-powered transmitters operating from 12–36 V supply. IC Role / Device Role / Timing Role: Precision differential amplifier with gain = 10 - rejects common-mode noise from long sensor cables and switching power supplies. Use Value: 90 dB SVRR ensures output stability despite 10% supply ripple; −40 °C to +125 °C rating matches industrial enclosure requirements. |
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 |
|---|---|---|---|
| TSV852IST | Higher GBP (1.8 MHz), lower Vio (1.5 mV max), but higher ICC (220 µA/amp) | Better for higher-frequency active filters; less suitable for ultra-low-power battery designs | Select when bandwidth >1.3 MHz is required and supply current budget allows +50% |
| LMV358IPT | Identical electrical specs, but in TSSOP8 (3.0 × 3.1 mm) - 40% smaller footprint, 37 °C/W RthJC | Preferred for space-constrained PCBs; requires tighter assembly process control due to fine pitch (0.65 mm) | Choose for miniaturized wearables where SO8 thermal margin is excessive and layout area is premium |
Compared with LMV358IDT, TSV852IST trades 50% higher supply current for +38% bandwidth and improved offset, while LMV358IPT retains identical analog performance in a smaller, thermally superior package-ideal when board area is constrained but SO8 rework is undesirable.

FAQ
What is the maximum capacitive load the LMV358IDT can drive without instability?
The LMV358IDT maintains 48° phase margin with 100 pF capacitive load and 600 Ω series resistance, as verified in Figure 11 of DS4539 Rev 10. Driving >100 pF directly risks peaking or oscillation; for larger loads, add a 10–100 Ω isolation resistor between output and capacitance.
Does the LMV358IDT support true rail-to-rail input at 125 °C?
Yes - per Table 2, the common-mode input range extends to both supply rails (VDD to VCC) across the full −40 °C to +125 °C range when VCC ≤ 5.5 V. At 6 V supply, Vicm is limited to VDD − 0.2 V to VCC + 0.2 V only at 25 °C.
Can LMV358IDT replace LM358 in existing designs?
Yes, with qualification - LMV358IDT offers rail-to-rail I/O, lower supply current (145 µA vs. 700 µA), and wider supply range (2.7–6 V vs. 3–36 V), but lacks the LM358's high-voltage tolerance. Verify that input signals stay within Vicm limits and that 6 V max supply suffices for your application.
Is there a lead-free and RoHS-compliant version of LMV358IDT?
Yes - LMV358IDT is supplied in ECOPACK2-compliant SO8 packaging, meeting RoHS Directive 2011/65/EU and REACH SVHC requirements. The "IDT" suffix denotes industrial-grade, lead-free, halogen-free, and green packaging per STMicroelectronics' ECOPACK specifications.
