Product details
Overview
LPV358IDRE4 from Texas Instruments is a dual, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power operational amplifier with 15 μA typical supply current per channel at 5 V, 152 kHz gain-bandwidth product, and −40°C to 125°C operating temperature range. It delivers rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ) and supports general-purpose signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the LPV358IDRE4 datasheet, LPV358IDRE4 pinout, LPV358IDRE4 application, or LPV358IDRE4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world use cases in low-voltage analog front-ends, and validated alternative parts for design flexibility and supply continuity.
Technical Context
The LPV358IDRE4 implements a CMOS input stage with rail-to-rail output stage, enabling operation down to 2.7 V while maintaining stable performance across −40°C to 125°C. Its input common-mode voltage range extends from −0.2 V to VCC+ − 0.8 V, supporting ground-referenced inputs in single-supply systems.
It achieves 152 kHz unity-gain bandwidth with only 15 μA per amplifier, delivering a high speed-power ratio. The device is internally compensated and remains stable driving capacitive loads up to 1000 pF, eliminating need for external compensation in most buffer and filtering applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - enables direct integration into 3.3 V and 5 V logic-compatible systems without level-shifting. |
| Supply Current (per channel) | 15 μA typical at 5 V - reduces total quiescent power to <150 μW per amplifier, critical for always-on sensor nodes. |
| Gain-Bandwidth Product | 152 kHz - supports DC-coupled amplification and low-frequency active filtering (e.g., anti-aliasing up to ~10 kHz). |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ - maximizes dynamic range in single-supply data acquisition stages. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - accepts signals at or slightly below ground, simplifying biasing in single-supply transducer interfaces. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive, industrial control, and extended-environment IoT deployments. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - meets robustness requirements for handling and board-level reliability in manufacturing. |
Pinout & Package
LPV358IDRE4 is housed in an 8-pin SOIC (D) package, 3.91 mm × 4.90 mm body size, with standard gull-wing leads and RoHS-compliant CU NIPDAU finish. Moisture Sensitivity Level is 1 (unlimited floor life at ≤30°C/60% RH).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 100 kΩ with rail-to-rail swing; requires no pull-up for open-drain compatibility. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance CMOS node (IIB = 2 nA typ); sensitive to PCB leakage in high-gain configurations. |
| 3 | IN+ A | Non-inverting input of Amplifier A - shares same input voltage range as IN− A; supports ground-referenced sensor inputs. |
| 4 | V− | Negative supply rail (GND in single-supply) - must be low-impedance; decoupling capacitor (0.1 μF) required near pin. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; enables independent dual-channel signal paths. |
| 6 | IN− B | Inverting input of Amplifier B - matched offset and bias characteristics to Amplifier A for differential pair implementations. |
| 7 | OUT B | Amplifier B output - identical drive capability and swing to OUT A; supports dual-channel buffering or independent gain stages. |
| 8 | V+ | Positive supply rail - accepts 2.7–5 V; internal regulation not present; supply rejection >50 dB ensures noise immunity. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher supply current (80 μA/channel at 125°C), wider input range (−0.3 V to VCC+ − 0.1 V), same SOIC-8 package. | Better for higher-speed applications (>1 MHz GBW needed) but consumes >5× more current at elevated temperature. | Select LMV358IDR only if bandwidth >1 MHz is required and thermal derating of supply current is acceptable. |
| TLV2372IDR | Lower input bias current (1 pA max), lower noise (17 nV/√Hz), but higher quiescent current (22 μA/channel) and narrower temp range (−40°C to 105°C). | Suitable for ultra-high-impedance pH or ion-selective electrode interfaces where bias current dominates error. | Choose TLV2372IDR when femtoampere-level input bias is mandatory; avoid if 125°C operation or sub-20 μA current is required. |
Compared with LMV358IDR and TLV2372IDR, LPV358IDRE4 uniquely balances ultra-low quiescent current (15 μA), extended 125°C rating, and rail-to-rail output in SOIC-8 - making it optimal for cost-sensitive, thermally demanding, battery-constrained dual-channel analog signal chains.

FAQ
What is the maximum operating temperature of the LPV358IDRE4?
The LPV358IDRE4 is rated for continuous operation from −40°C to +125°C, as confirmed in the SLOS433I datasheet Section 4 (Recommended Operating Conditions). This extended temperature grade makes it suitable for under-hood automotive, industrial motor control, and outdoor IoT edge nodes where ambient temperatures exceed standard commercial limits. The 'I' suffix explicitly denotes the 125°C specification.
Does the LPV358IDRE4 support true rail-to-rail input?
No - the LPV358IDRE4 features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V (SLOS433I, Section 6). While it accepts inputs down to 0.2 V below ground (enabling ground-referenced sensors), it cannot accept signals at the positive rail. For true rail-to-rail input, consider TI's TLV9002 or OPA333 families.
What package type and lead finish does LPV358IDRE4 use?
The LPV358IDRE4 uses an 8-pin SOIC (Package Drawing D) with 3.91 mm × 4.90 mm body dimensions. Its lead finish is CU NIPDAU (copper with nickel-palladium-gold), compliant with RoHS and halogen-free standards (Green Eco Plan), and rated for MSL Level-1 (unlimited floor life at ≤30°C/60% RH).
Can LPV358IDRE4 drive capacitive loads without oscillation?
Yes - the LPV358IDRE4 is characterized for stability with capacitive loads up to 1000 pF (SLOS433I, Section 1). This is verified in Figures 14–15 (frequency response vs. CL), showing ≥74° phase margin at 5 V with 1000 pF. No external isolation resistor is required for typical LCD bias, sampling capacitor, or long-trace driving - reducing BOM count and layout complexity.
How does the supply current of LPV358IDRE4 vary with temperature and voltage?
At 5 V supply, LPV358IDRE4 draws 15 μA typical per channel at 25°C, rising to 24 μA at 85°C and 40 μA at 125°C (SLOS433I, Table 6). At 2.7 V, typical current is 8 μA at 25°C. This monotonic increase is documented in Figure 1 (ICC vs. VCC), confirming predictable thermal behavior for battery-life modeling in wide-temperature deployments.
