Product details
Overview
LMV358LIPT 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, 7 mV max input offset voltage at 25 °C, and operates across -40 °C to +125 °C. It is used in portable medical sensors for signal conditioning of weak biopotential signals.
For engineers reviewing the LMV358LIPT datasheet, LMV358LIPT pinout, LMV358LIPT application, or LMV358LIPT equivalent, key selection criteria include rail-to-rail output swing (≤180 mV from rails), industrial temperature range support, low quiescent current for battery longevity, and TSSOP8 package compatibility with high-density PCB layouts.
Technical Context
The LMV358LIPT integrates two independent op-amps in a single TSSOP8 package, each featuring rail-to-rail output stage capable of sourcing up to 70 mA and sinking up to 43 mA under 5 V supply. Its input common-mode range extends from (VCC–) – 0.2 V to (VCC+) – 1 V, enabling ground-sensing capability without phase reversal.
Designed for 2.7 V to 5.5 V single-supply operation, it achieves 60° phase margin and 10 dB gain margin with 200 pF capacitive load, supporting stable unity-gain buffer configurations in active filtering and sensor front-end stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - enables direct integration into Li-ion (3.7 V nominal) and 3.3 V logic systems without level-shifting. |
| Gain Bandwidth Product | 1.3 MHz - supports audio-band signal amplification and anti-aliasing filter design up to ~100 kHz. |
| Input Offset Voltage | 7 mV max at 25 °C - ensures ≤0.7% full-scale error in 1 V reference-based instrumentation circuits. |
| Quiescent Current | 250 µA max per channel at 5 V - allows >1-year battery life in coin-cell-powered devices operating at 10 µA average system current. |
| Output Swing | 180 mV from rails (RL = 10 kΩ) - preserves dynamic range in 3.3 V ADC interfaces requiring ≥3.1 V peak output. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive cabin sensors and industrial motor control feedback paths. |
| Input Noise Density | 30 nV/√Hz at 1 kHz - suitable for amplifying microvolt-level ECG/EEG signals without dominant amplifier noise contribution. |
Pinout & Package
TSSOP8 package: 3 mm × 4.4 mm body, 0.65 mm pitch, 1.05 mm max height, RoHS-compliant ECOPACK®2, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts differential input signal referenced to non-inverting input; supports DC-coupled sensor interfaces. |
| 2 | Non-inverting Input (Channel 1) | High-impedance node (60 nA max bias current) for precision voltage referencing or high-Z transducer connections. |
| 3 | Output (Channel 1) | Rail-to-rail capable output driving 10 kΩ loads to within 180 mV of VCC or GND. |
| 4 | VCC– (Ground) | Power return path; requires local 10 nF ceramic decoupling capacitor placed <1 mm from pin. |
| 5 | VCC+ (Supply) | Positive supply input; accepts 2.7–5.5 V; internal ESD protection rated to 4 kV HBM. |
| 6 | Non-inverting Input (Channel 2) | Independent second amplifier input; electrically isolated from Channel 1 except shared supply rails. |
| 7 | Inverting Input (Channel 2) | Second differential input pair; identical electrical specs to Channel 1 inputs. |
| 8 | Output (Channel 2) | Second rail-to-rail output; usable for dual-sensor conditioning or composite feedback loops. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 180 mV of both supply rails under 10 kΩ load - maximizes usable signal range in single-supply 3.3 V systems. |
| Low input offset drift | 5 µV/°C over -40 °C to +125 °C - limits thermal-induced baseline shift to <0.5 mV across full industrial temperature range. |
| High CMRR | 75 dB minimum - rejects common-mode noise from noisy digital supplies in mixed-signal PCB environments. |
| Stable with capacitive loads | Maintains 60° phase margin with up to 200 pF load - eliminates need for isolation resistors in ADC driver applications. |
| Ultra-low power | 130–250 µA per channel at 5 V - enables always-on sensor monitoring in energy-harvesting IoT nodes. |
Applications

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 3 MHz GBP but 550 µA/channel ICC; 10 µV/°C VOS drift | Better bandwidth for fast pulse amplification; higher power disqualifies ultra-low-power designs | Select when >2 MHz signal bandwidth required and battery life is secondary to speed |
| LMV358IDR | Same architecture but wider -40 °C to +105 °C temp range; 1.2 MHz GBP; 2.5 mV VOS typ | Lower typical offset benefits precision DC-coupled systems; reduced max temperature limits under-hood use | Select for cost-sensitive consumer applications where extended industrial temp is unnecessary |
Compared with TLV2372IDR and LMV358IDR, LMV358LIPT uniquely balances ultra-low quiescent current (250 µA), extended temperature range (-40 °C to +125 °C), and sufficient 1.3 MHz bandwidth for sensor signal conditioning-making it optimal for battery-powered industrial and medical edge devices requiring long-term thermal stability.

FAQ
Is LMV358LIPT pin-compatible with standard LM358 SO8 packages?
No. LMV358LIPT uses a TSSOP8 package with 0.65 mm pitch and different pin mapping: pins 1–3 and 6–8 serve Channel 1 and Channel 2 inputs/outputs, while pin 4 is VCC– and pin 5 is VCC+. Standard LM358 SO8 has pin 4 as VCC–, pin 8 as VCC+, and inverted channel ordering. Direct replacement requires PCB redesign.
What is the maximum capacitive load the LMV358LIPT can drive without instability?
LMV358LIPT maintains 60° phase margin with up to 200 pF capacitive load when configured as a unity-gain buffer, per Figure 9 in the datasheet. Driving >200 pF requires an isolation resistor (typically 10–100 Ω) between output and load to preserve stability in ADC driver or cable-driving applications.
Does LMV358LIPT support true rail-to-rail input?
No. LMV358LIPT features rail-to-rail *output* only. Its input common-mode range extends from (VCC–) – 0.2 V to (VCC+) – 1 V, meaning it accepts signals down to ground but not up to VCC+. For true rail-to-rail input, consider ST's TSX922IYDT or similar dual RRO+RRIO op-amps.
Can LMV358LIPT operate from a single 2.7 V supply with meaningful output swing?
Yes. At 2.7 V supply, LMV358LIPT delivers ≥2.52 V high-level and ≤180 mV low-level output swing into 10 kΩ (per Table 3), providing 2.34 V of usable linear range - sufficient for driving 12-bit SAR ADCs with 2.5 V reference or interfacing with 2.7 V logic I/O.
