Product details
Overview
LPV358ID 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 across industrial and automotive temperature ranges (−40°C to +125°C). It delivers 152 kHz gain-bandwidth, 70 dB CMRR, 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 LPV358ID datasheet, LPV358ID pinout, LPV358ID application, or LPV358ID equivalent, key selection criteria include its −40°C to 125°C extended-temperature qualification, 15 μA supply current per amplifier, rail-to-rail output capability at 2.7 V operation, and SOIC-8 package compatibility with legacy LMV358 layouts.
Technical Context
The LPV358ID employs a complementary input stage enabling rail-to-rail input common-mode range (−0.2 V to VCC+ − 0.8 V) and eliminates crossover distortion. Its internal biasing supports stable operation with capacitive loads up to 1000 pF without external compensation.
Designed as a low-power variant of the LMV358 family, it maintains functional compatibility while reducing supply current by ~50% versus standard versions - achieved via optimized transistor sizing and quiescent current control circuitry that preserves DC accuracy (7 mV max input offset voltage) and noise performance (146 nV/√Hz at 1 kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - enables direct operation from single-cell Li-ion or 3.3 V logic rails without regulation. |
| Supply Current (per channel) | 15 μA typical at 5 V - supports multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 152 kHz - sufficient for anti-aliasing filters, slow-settling transducer amplifiers, and DC-coupled signal chains. |
| Input Offset Voltage | 7 mV max at 25°C - ensures <1% error in 100-mV full-scale sensor outputs without trimming. |
| Output Swing (100-kΩ load) | VCC+ − 3.5 mV / VCC− + 90 mV - maximizes dynamic range in low-voltage data acquisition systems. |
| Common-Mode Input Range | −0.2 V to VCC+ − 0.8 V - accepts inputs below ground and near supply rails for single-supply front-end design. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and harsh-environment monitoring. |
Pinout & Package
LPV358ID is packaged in an 8-pin SOIC (D package) with standard industry footprint and thermal characteristics (θJA = 97°C/W). This package supports automated assembly and provides robust thermal performance for continuous operation at ambient temperatures up to 125°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 17 mA sourcing / 72 mA sinking at 5 V. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (50 nA max input bias current) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts signals from −0.2 V to VCC+ − 0.8 V, including ground-referenced sensors. |
| 4 | VCC− | Negative supply rail - connected to system ground in single-supply configurations. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; supports dual-channel independent signal paths. |
| 6 | IN− B | Inverting input of Amplifier B - matched input characteristics to Pin 2 for consistent dual-amplifier performance. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to Pin 1; enables dual-sensor conditioning or signal splitting. |
| 8 | VCC+ | Positive supply rail - operates from 2.7 V to 5 V; internal ESD protection exceeds 2 kV HBM. |
Key Features
| Feature | Design Value |
|---|---|

| Stable with 1000-pF load | Operates without external compensation into capacitive loads typical of long PCB traces or ADC input capacitance. |
| Extended temperature range | Specified from −40°C to +125°C - meets AEC-Q100 Grade 1 requirements for automotive cabin and powertrain modules. |
| Low input bias current | 2 nA typical at 25°C - minimizes voltage error across high-impedance sensor bridges and photodiode feedback resistors. |

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 (11 mV max), same SOIC-8 package. | Less suitable for ultra-low-power designs but offers higher drive strength (60 mA sink). | Select LMV358IDR only when higher output current or legacy LMV358 pinout compatibility is required over power savings. |
| TLV2372IDR | Lower supply current (1 μA per channel), lower bandwidth (100 kHz), same −40°C to 125°C rating and SOIC-8 footprint. | Better for nano-power sensor wake-up circuits but insufficient for >50 kHz signal paths. | Choose TLV2372IDR when sub-μA sleep current dominates design priority and bandwidth demand is ≤10 kHz. |
Compared with LMV358IDR and TLV2372IDR, LPV358ID uniquely balances 15 μA supply current, 152 kHz bandwidth, and rail-to-rail output - making it optimal for mid-tier low-power industrial and automotive signal chains where both efficiency and speed matter.

FAQ
What is the maximum operating temperature specification for LPV358ID?
The LPV358ID is fully specified from −40°C to +125°C, meeting extended-temperature requirements for automotive under-hood and industrial control applications. This rating is confirmed in the "recommended operating conditions" table of the SLOS433I datasheet, where TA (operating free-air temperature) for LPV3xxI devices is explicitly listed as −40°C to 125°C.
Does LPV358ID support rail-to-rail input operation?
LPV358ID supports rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range is −0.2 V to VCC+ − 0.8 V, meaning it accepts inputs down to 0.2 V below ground and up to 0.8 V below the positive rail. This is sufficient for ground-referenced sensors but does not include the full supply rails at the input stage.
What is the typical supply current consumption of LPV358ID at 2.7 V?
At 2.7 V supply and 25°C, the typical supply current for LPV358ID is 8 μA per channel (16 μA total for both amplifiers), as stated in the "2.7-V electrical characteristics" table. This value increases to 15 μA per channel at 5 V, confirming its ultra-low-power profile across the full operating voltage range.
Is LPV358ID pin-compatible with standard LMV358 variants?
Yes, LPV358ID uses the same SOIC-8 (D) package and identical pinout as LMV358D, LMV358DR, and LMV358IDR. The device is functionally compatible and designed as a drop-in low-power replacement - verified by matching pin assignments in the "LPV358 . . . D, DDU, OR DGK PACKAGE (TOP VIEW)" diagram and ordering information tables.
What load capacitance can LPV358ID drive without instability?
LPV358ID is characterized as stable with capacitive loads up to 1000 pF, as explicitly stated in the "Features" section of the SLOS433I datasheet. This stability holds across the full operating temperature and supply voltage range, eliminating the need for isolation resistors when driving ADC inputs or long PCB traces.
