Product details
Overview
LMV358IYPT 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 at 2.7 V, delivers 1 MHz gain bandwidth, and supports extended common-mode input range (VDD − 0.2 V to VCC + 0.2 V) - enabling direct sensing near supply rails in glucose meters and battery-powered instrumentation.
For engineers reviewing the LMV358IYPT datasheet, LMV358IYPT pinout, LMV358IYPT application, or LMV358IYPT equivalent, this device is selected for cost-sensitive, low-power analog signal conditioning where rail-to-rail swing, thermal stability across −40°C to +125°C, and AEC-Q100 qualified automotive-grade reliability are required.
Technical Context
The LMV358IYPT implements a CMOS input stage with rail-to-rail input common-mode range extending beyond both supply rails by ±0.2 V at 25°C, and full rail-to-rail output swing into 2 kΩ loads. Its 1 MHz unity-gain bandwidth and 0.45 V/µs slew rate support stable closed-loop operation in DC-coupled sensor interfaces and active filters up to ~100 kHz.
It features 85 dB typical CMRR and 90 dB typical PSRR at 5 V supply, with input offset voltage ≤3 mV at 25°C and drift of 2 µV/°C - enabling precision amplification without external trimming in medical and industrial front-ends. ESD tolerance is rated at 2 kV HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - compatible with single-cell Li-ion (3.0–3.7 V) and two-cell alkaline (3.0–3.2 V) power rails. |
| Supply Current per Amplifier | 145 µA at 2.7 V - enables >1-year battery life in always-on glucose meter front-ends using CR2032. |
| Gain Bandwidth Product | 1 MHz at 2.7 V, 1.3 MHz at 5 V - sufficient for anti-aliasing filters, transimpedance stages, and DC-coupled gain blocks. |
| Input Offset Voltage | ≤3 mV at 25°C - allows direct amplification of µV-level biosensor outputs without nulling circuitry. |
| Common-Mode Input Range | VDD − 0.2 V to VCC + 0.2 V - supports single-supply operation with inputs tied to ground or VCC. |
| Output Voltage Swing | Rail-to-rail - delivers full dynamic range into ADC reference buffers or LED drivers without level-shifting. |
| ESD Rating (HBM) | 2 kV - meets IEC 61000-4-2 Level 2 for handheld medical devices handling human contact. |
Pinout & Package
LMV358IYPT is housed in a thermally enhanced, lead-free, RoHS-compliant TSSOP-8 package (3.0 mm × 4.4 mm × 1.05 mm), optimized for high-density PCB layouts and automated assembly. The package features 0.65 mm pitch leads and 0.45–0.75 mm lead length for reliable reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; drives 2 kΩ load to within 180 mV of rails at 5 V. |
| 2 (−IN A) | Inverting input A | Accepts differential signals up to ±1 V; requires series resistor if |Vid| > 1 V to limit current to <1 mA. |
| 3 (+IN A) | Non-inverting input A | Supports common-mode range down to VDD − 0.2 V - enables ground-referenced sensor biasing. |
| 4 (V−) | Negative supply / GND | Reference node for dual-supply (±V) or single-supply (0 V) operation; connects to system ground plane. |
| 5 (+IN B) | Non-inverting input B | Independent channel input; identical specs to Pin 3 - supports dual-sensor or reference+signal architecture. |
| 6 (−IN B) | Inverting input B | Matches Pin 2 behavior; allows independent feedback networks for each amplifier channel. |
| 7 (OUT B) | Amplifier B output | Electrically isolated from OUT A; enables dual-path signal conditioning on one die. |
| 8 (V+) | Positive supply | Accepts 2.7–6 V; internal ESD protection clamps to V+ and V−; decoupling capacitor required within 1 cm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal capture and drive in single-supply 3.3 V systems without level shifters or charge pumps. |

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 (1.7 MHz), lower input bias (1 pA vs. 16 nA), but higher supply current (220 µA). | Better for high-frequency sensor interfaces (e.g., ultrasonic flow meters); less suitable for ultra-low-power battery use. | Select when bandwidth >1.3 MHz is required and power budget allows +50% ICC increase. |
| LMV358IDT | Same core specs, SO-8 package (larger footprint, higher RthJA = 125°C/W vs. 120°C/W), non-automotive grade. | Lower cost for industrial consumer products; lacks AEC-Q100 qualification and extended temp screening. | Select for cost-driven non-automotive designs where −40°C to +85°C operation suffices and board space permits SO-8. |
Compared with TSV852IST, LMV358IYPT trades bandwidth and input bias for 35% lower supply current and automotive qualification; compared with LMV358IDT, it adds AEC-Q100 reliability at identical electrical performance but in a smaller, thermally superior TSSOP-8 package.

FAQ
Is LMV358IYPT pin-compatible with LMV358IDT?
Yes - both share identical pinout (SO-8 and TSSOP-8 are footprint-compatible per JEDEC MO-153), allowing drop-in replacement in existing layouts. However, LMV358IYPT's TSSOP-8 has finer pitch (0.65 mm vs. 1.27 mm) and requires adjusted stencil aperture and reflow profile for reliable solder joints.
What is the maximum capacitive load LMV358IYPT can drive stably?
LMV358IYPT remains unity-gain stable with up to 100 pF capacitive load when driving 10 kΩ parallel resistance, as verified in DS4539 Figure 11. For loads >100 pF, a 10–100 Ω isolation resistor in series with the output is recommended to maintain phase margin ≥44°.
Does LMV358IYPT support true single-supply operation below 2.7 V?
No - the absolute minimum supply voltage is 2.7 V per datasheet Table 2. Operation below this risks degraded CMRR, increased input offset, and failure to achieve rail-to-rail output swing. For sub-2.7 V systems, consider ST's TSV851 (1.5 V min) or MCP6002 (1.8 V min).
How does the AEC-Q100 qualification of LMV358IYPT impact its use in industrial applications?
AEC-Q100 Grade 1 qualification ensures tested reliability at −40°C to +125°C, including HTOL, TC, and ESD stress - providing design margin for harsh industrial environments. While not mandatory for non-automotive use, it guarantees extended lifetime, reduced infant mortality, and consistent parametric performance across temperature extremes.
