Product details
Overview
LPV358IDE4 from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5 V), low-power (15 μA per channel at 5 V) applications. It delivers 152 kHz gain-bandwidth product, input common-mode range extending to −0.2 V below VCC− and up to VCC+ − 0.8 V, and rail-to-rail output swing within 3.5 mV of VCC+ and 90 mV of VCC− at 100-kΩ load - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the LPV358IDE4 datasheet, LPV358IDE4 pinout, LPV358IDE4 application, or LPV358IDE4 equivalent, this device is selected for ultra-low quiescent current, guaranteed operation from −40°C to 125°C, stable performance with 1000-pF capacitive loads, and compatibility with single-supply systems requiring ground-sensing inputs and near-rail outputs.
Technical Context
The LPV358IDE4 integrates two independent amplifiers in a single SOIC-8 package, each featuring complementary-input-stage architecture enabling rail-to-rail input common-mode voltage range (VICR = −0.2 V to VCC+ − 0.8 V) and rail-to-rail output swing. Its internal biasing achieves 15 μA typical supply current per channel at 5 V while maintaining 152 kHz GBW and 0.1 V/μs slew rate.
Designed as a low-power variant of the LMV358 family, it exhibits no crossover distortion, supports stable operation with 1000-pF capacitive loads, and meets JESD 78 Class II latch-up performance (>100 mA). ESD protection exceeds 2000-V HBM, 200-V MM, and 1000-V CDM per JESD 22.
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 single-supply systems without level-shifting. |
| Quiescent Current (per channel) | 15 μA at 5 V - reduces system power budget in always-on sensor front-ends and wearable devices. |
| Gain-Bandwidth Product | 152 kHz - supports DC-coupled filtering and low-frequency amplification (e.g., thermocouple, strain gauge signals). |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ load - maximizes dynamic range in low-voltage ADC driver stages. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows direct sensing of signals referenced to ground in single-supply configurations. |
| Operating Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-environment IoT nodes. |
| Input Offset Voltage (max) | 11 mV over −40°C to +125°C - suitable for cost-sensitive, non-precision signal conditioning where trimming is omitted. |
Pinout & Package
LPV358IDE4 is housed in an 8-pin SOIC (D) package with standard JEDEC outline, 1.27-mm pitch, and 3.90-mm body width. The package is RoHS-compliant, green (no Sb/Br), and moisture sensitivity level (MSL) 1 rated for 260°C peak reflow.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next stage; rail-to-rail capable up to 100-kΩ. |
| 2 | IN− A | Inverting input of Amplifier A - accepts feedback network or differential signal path. |
| 3 | IN+ A | Non-inverting input of Amplifier A - connects to sensor, reference, or signal source with ground-referenced capability. |
| 4 | VCC− | Negative supply rail (typically GND) - shared return for both amplifiers and bias circuitry. |
| 5 | IN+ B | Non-inverting input of Amplifier B - independent channel for dual-path signal processing (e.g., active filter pair). |
| 6 | IN− B | Inverting input of Amplifier B - supports separate feedback configuration from Amplifier A. |
| 7 | OUT B | Amplifier B output - fully independent output stage; identical electrical specs to OUT A. |
| 8 | VCC+ | Positive supply rail (2.7–5 V) - powers both amplifiers; low current draw minimizes supply regulation burden. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher supply current (80 μA per channel at 125°C), wider input offset range (15 mV max), same SOIC-8 package. | Targeted at general-purpose industrial use where power is less constrained but higher speed (1 MHz GBW) is needed. | Select LMV358IDR when >152 kHz bandwidth is required and 80-μA quiescent current is acceptable. |
| TLV2372IDR | Lower supply current (2.5 μA per channel), lower GBW (110 kHz), same −40°C to +125°C rating and SOIC-8 footprint. | Optimized for ultra-low-power battery longevity in intermittently active sensor nodes, not continuous operation. | Choose TLV2372IDR only if <5 μA total dual-channel current is mandatory and 110 kHz GBW suffices. |
Compared with LMV358IDR and TLV2372IDR, the LPV358IDE4 uniquely balances 152 kHz bandwidth, 15 μA per channel consumption, and 11-mV input offset over −40°C to +125°C - making it the optimal choice for always-on, cost-sensitive, medium-bandwidth analog signal chains in automotive and industrial environments.

FAQ
What is the maximum operating temperature range for the LPV358IDE4?
The LPV358IDE4 is fully specified and tested from −40°C to +125°C, meeting automotive-grade thermal requirements. This rating applies across all electrical parameters including input offset voltage (max 11 mV), supply current (max 80 μA per channel), and output swing - ensuring reliable operation in under-hood or industrial control environments without derating.
Does the LPV358IDE4 support rail-to-rail input operation?
No, the LPV358IDE4 does not support rail-to-rail input. Its input common-mode voltage range is −0.2 V to VCC+ − 0.8 V, meaning it accepts signals down to 0.2 V below ground and up to 0.8 V below the positive rail. However, the input range does include ground, enabling true single-supply operation with ground-referenced sensors.
Can the LPV358IDE4 drive a 1000-pF capacitive load without oscillation?
Yes, the LPV358IDE4 is explicitly characterized and guaranteed stable with capacitive loads up to 1000 pF, as confirmed in the datasheet Figure 14 and 15 frequency response plots. This eliminates the need for external isolation resistors in ADC driver or cable-driving applications, simplifying design and reducing component count.
What is the supply current of the LPV358IDE4 at 2.7 V and 25°C?
At 2.7 V and 25°C, the LPV358IDE4 draws 15 μA per channel (30 μA total for both amplifiers), matching its 5-V specification. This consistent ultra-low quiescent current across the 2.7–5 V supply range makes it ideal for systems powered by depleting primary cells or energy-harvesting sources.
Is the LPV358IDE4 pin-compatible with standard SOIC-8 op-amps like the LM358?
No, the LPV358IDE4 is not pin-compatible with the LM358. While both use SOIC-8 packages, the LPV358IDE4 follows the industry-standard dual-op-amp pinout (OUT A, IN− A, IN+ A, VCC−, IN+ B, IN− B, OUT B, VCC+), whereas the LM358 uses a different arrangement (IN− A, IN+ A, OUT A, VCC−, IN− B, IN+ B, OUT B, VCC+). PCB layout must follow the LPV358IDE4-specific pin mapping.
