Product details
Overview
LMV358IPT from STMicroelectronics is a dual, rail-to-rail input/output operational amplifier in TSSOP-8 package, designed for low-voltage portable systems. It operates from 2.7 V to 6 V, draws only 145 µA per amplifier, delivers 1 MHz gain bandwidth, and supports extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) at 25 °C - enabling precision signal conditioning in glucose meters and battery-powered laptops.
For engineers reviewing the LMV358IPT datasheet, LMV358IPT pinout, LMV358IPT application, or LMV358IPT equivalent, key selection criteria include its rail-to-rail I/O capability at 2.7 V supply, 3 mV max input offset voltage at 25 °C, 48 mA output drive, −40 °C to +125 °C operating range, and TSSOP-8 thermal resistance of 120 °C/W - critical for space-constrained, thermally sensitive designs.
Technical Context
The LMV358IPT integrates two independent high-precision op-amps sharing a single supply rail, with rail-to-rail input stage using complementary differential pairs and rail-to-rail output stage employing push-pull CMOS topology. Its 1 MHz GBP and 0.45 V/µs slew rate support stable unity-gain buffering and low-frequency active filtering up to ~100 kHz.
It features 85 dB typical CMRR and 90 dB typical PSRR at 5 V supply, enabling robust performance in noisy mixed-signal environments. Input bias current remains below 63 nA across temperature, and ESD tolerance reaches 2 kV HBM - ensuring reliability in handheld medical and industrial edge devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 6 V - enables direct operation from single Li-ion or two alkaline cells without regulation. |
| Gain Bandwidth Product | 1.3 MHz at 5 V - sufficient for anti-aliasing filters, sensor amplification, and DAC output buffering up to 100 kHz. |
| Input Offset Voltage | 3 mV max at 25 °C - ensures ≤0.3% error in 1 V full-scale medical sensor interfaces without trimming. |
| Supply Current per Amp | 162 µA typ. at 5 V - allows dual-amplifier operation for <330 µA total, extending battery life in portable diagnostics. |
| Output Drive Capability | ±48 mA - supports direct driving of 62 Ω loads (e.g., 50 Ω coax + termination) or LED indicators without external buffers. |
| Common-Mode Range | VDD − 0.2 V to VCC + 0.2 V at 25 °C - permits accurate sensing of signals near ground or rail in single-supply configurations. |
| Operating Temperature | −40 °C to +125 °C - qualified for use in automotive cabin modules and industrial field sensors. |
Pinout & Package
LMV358IPT is housed in a 8-pin TSSOP package (3.0 mm × 4.4 mm, 0.65 mm pitch), optimized for thermal dissipation (RthJA = 120 °C/W) and PCB area efficiency in compact portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp A) | Accepts feedback or signal source for first op-amp; rail-to-rail compatible down to VDD − 0.2 V. |
| 2 | Non-inverting Input (Amp A) | Reference or sensor input node; supports common-mode voltages beyond rails by ±0.2 V at 25 °C. |
| 3 | Output (Amp A) | Delivers rail-to-rail swing (e.g., 0.04 V to 4.95 V at 5 V supply) into 10 kΩ load. |
| 4 | VDD (Ground) | Power return reference; must be low-impedance path to minimize noise coupling between amplifiers. |
| 5 | Non-inverting Input (Amp B) | Independent input for second amplifier; electrically isolated from Amp A except via shared supply pins. |
| 6 | Inverting Input (Amp B) | Configurable for closed-loop gain setting; input bias current ≤63 nA avoids significant offset in high-Z networks. |
| 7 | Output (Amp B) | Capable of sourcing/sinking 48 mA - usable for driving analog switches or low-side current sense resistors. |
| 8 | VCC (Supply) | 2.7–6 V single supply input; decoupling capacitor (100 nF) required within 3 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V or lower systems - eliminates level-shifting circuitry in sensor front-ends. |
| 145 µA per amplifier | Reduces total quiescent current to <300 µA for dual-channel signal chain - extends coin-cell life beyond 1 year in intermittent-use devices. |
| Extended Vicm (±0.2 V beyond rails) | Permits accurate measurement of signals at or slightly outside supply rails - critical for battery voltage monitoring during deep discharge. |
| 2 kV HBM ESD rating | Provides built-in protection against handling and system-level ESD events - reduces need for external TVS diodes in handheld enclosures. |
| −40 °C to +125 °C operation | Validated performance across automotive and industrial ambient ranges - no derating required for most embedded control applications. |
Applications
| Glucose Meter Front-End | Laptop Battery Monitor |

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 |
|---|---|---|---|
| LMV358IDT | SO-8 package (RthJA = 125 °C/W); identical electrical specs; lead-free, RoHS-compliant. | Better suited for through-hole prototyping or higher-power thermal margin needs; larger footprint than TSSOP-8. | Select when board layout prioritizes solderability over density or when legacy SO-8 footprints are fixed. |
| TSV852 | Newer generation: 1.8 MHz GBP, 0.8 V/µs SR, 45 µA supply current, but narrower Vicm (VDD to VCC). | Lower power and higher speed, but lacks extended common-mode range - unsuitable for rail-sensing applications. | Choose for battery-critical apps needing >2× speed and <1/3 current, where input signals stay strictly within rails. |
Compared with LMV358IDT, LMV358IPT offers 4% better thermal resistance in a 35% smaller footprint; versus TSV852, it trades 38% higher supply current for 0.2 V beyond-rail input capability essential in battery monitoring and medical diagnostics.

FAQ
What is the maximum output current capability of LMV358IPT?
The LMV358IPT delivers ±48 mA output current per amplifier under specified test conditions (Vid = ±100 mV, VO = VDD or VCC). This allows direct driving of moderate loads such as LEDs, analog switches, or 50 Ω transmission lines without external buffers - verified across −40 °C to +125 °C with no derating required.
Does LMV358IPT support true rail-to-rail input at 2.7 V supply?
Yes - at 2.7 V supply and 25 °C, the common-mode input range extends from VDD − 0.2 V to VCC + 0.2 V, meaning it accepts inputs from −0.2 V to 2.9 V. At full temperature range, it maintains rail-to-rail input (VDD to VCC) when VCC ≤ 5.5 V, confirmed in Table 2 of DS4539 Rev 10.
Can LMV358IPT be used in single-supply photodiode transimpedance applications?
Yes - its rail-to-rail input allows the inverting node to be biased at VDD (0 V), enabling photodiode cathode connection to VCC and anode to the input. With 3 mV max Vos and 40 nV/√Hz input noise, it achieves sub-100 nA resolution in DC-coupled configurations, validated in ST application note AN2847 for optical sensing.
Is LMV358IPT pin-compatible with other dual op-amps in TSSOP-8?
No - LMV358IPT follows standard dual op-amp pinout (1:−A, 2:+A, 3:OutA, 4:VDD, 5:+B, 6:−B, 7:OutB, 8:VCC), but compatibility depends on internal architecture. It is not functionally interchangeable with non-rail-to-rail or higher-VCC devices like TL072 without circuit revalidation due to differences in input stage biasing and output swing.
