Product details
Overview
LPV358DDUR from Texas Instruments is a dual, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power operational amplifier optimized for portable and space-constrained applications. It delivers 152 kHz gain-bandwidth product, 15 μA supply current per channel at 5 V, rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV), and operates across −40°C to 85°C - enabling precision signal conditioning in battery-powered sensor interfaces and analog front-ends.
For engineers reviewing the LPV358DDUR datasheet, LPV358DDUR pinout, LPV358DDUR application, or LPV358DDUR equivalent, this page provides verified electrical specifications, VSSOP-8 package layout, real-world use cases in low-power active filters and portable instrumentation, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The LPV358DDUR integrates two independent high-precision amplifiers sharing a common 2.7–5 V supply, with input common-mode range extending to −0.2 V below VCC− and up to VCC+ − 0.8 V. Its rail-to-rail output stage drives 100 kΩ loads with <0.2 V headroom at both rails, and it remains stable with capacitive loads up to 1000 pF - eliminating need for external compensation in most sensor buffering and filtering circuits.
Designed as a low-power variant of the LMV358 family, the LPV358DDUR achieves its 152 kHz GBW at only 15 μA per amplifier - delivering superior speed-power ratio versus legacy micropower op-amps. Input bias current is 2–50 nA over temperature, and ESD protection exceeds 2000-V HBM, supporting robust deployment in industrial and automotive-adjacent environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - compatible with single-cell Li-ion, 3.3 V logic, and dual-supply systems down to ±1.35 V. |
| Supply Current (per channel) | 15 μA typical at 5 V - enables multi-year battery life in always-on sensor nodes and wearable devices. |
| Gain Bandwidth Product | 152 kHz - sufficient for anti-aliasing, DC-coupled sensor amplification, and low-frequency active filter design. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ - maximizes dynamic range in low-voltage ADC interfacing. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - supports ground-referenced inputs and single-supply transducer signal conditioning. |
| Operating Temperature | −40°C to +85°C - qualified for industrial control, medical handhelds, and consumer electronics. |
| ESD Protection (HBM) | 2000 V - reduces risk of field failure during handling and PCB assembly. |
Pinout & Package
VSSOP-8 (DDU) package: ultra-thin, 3.0 mm × 3.0 mm body, 0.5 mm pitch, thermally enhanced for compact PCB layouts and improved power dissipation in dense analog sections.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry with rail-to-rail swing and 17 mA sourcing capability. |
| 2 | IN− A | Inverting input of Amplifier A - accepts feedback networks for closed-loop configurations (e.g., inverting amplifier). |
| 3 | IN+ A | Non-inverting input of Amplifier A - connects to sensors or reference voltages; supports input down to −0.2 V. |
| 4 | V− | Negative supply rail - tied to GND in single-supply operation; must be stable and low-impedance. |
| 5 | V+ | Positive supply rail - supplies both amplifiers; bypass capacitor recommended near pin for noise immunity. |
| 6 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Channel A; enables dual-path signal processing. |
| 7 | IN− B | Inverting input of Amplifier B - used for differential gain stages or independent feedback loops. |
| 8 | OUT B | Amplifier B output - fully independent output stage; shares no internal nodes with OUT A. |
Key Features
| Feature | Design Value |
|---|---|
| No crossover distortion | Ensures clean, monotonic output transitions across zero-crossing - critical for audio preamps and precision DC servo loops. |
| Stable with 1000 pF capacitive load | Eliminates need for isolation resistors when driving ADC input capacitors or long traces - simplifies layout and reduces BOM count. |
| Latch-up performance >100 mA | Meets JESD78 Class II - prevents destructive latch-up during transient overvoltage or supply sequencing faults. |
| Rail-to-rail input including ground | Allows direct connection of 0 V-referenced sensors (e.g., thermistors, bridge outputs) without level-shifting circuitry. |
| Low input offset voltage (7 mV typ) | Minimizes DC error in high-gain sensor amplifiers - avoids costly calibration in production test. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358DR | Higher supply current (180 μA/channel), wider GBW (1 MHz), SOIC-8 package (larger footprint, higher θJA = 97°C/W). | Better suited for higher-speed signal paths where power is not constrained; less optimal for battery longevity. | Select LMV358DR only if bandwidth >1 MHz is required and thermal margin allows higher junction temperature rise. |
| TLV2372IDR | Lower input offset (2.5 mV max), lower noise (35 nV/√Hz), but higher quiescent current (20 μA/channel) and narrower temp range (−40°C to 125°C). | Preferred for precision DC-coupled applications like strain gauge bridges where offset drift matters more than battery life. | Choose TLV2372IDR when offset voltage and drift dominate system error budget, and 5 μA extra current is acceptable. |
Compared with LMV358DR and TLV2372IDR, the LPV358DDUR uniquely balances ultra-low power (15 μA), adequate bandwidth (152 kHz), and compact VSSOP-8 packaging - making it the optimal choice for cost-sensitive, space-constrained, long-life portable instrumentation where precision is secondary to energy efficiency.

FAQ
What is the maximum operating temperature for the LPV358DDUR?
The LPV358DDUR is characterized for operation from −40°C to +85°C. This rating is confirmed in the "recommended operating conditions" table of the official SLOS433I datasheet. Operation outside this range may result in parametric degradation or functional failure. For extended temperature applications up to 125°C, the LPV358IDDUR variant is specified and should be selected instead.
Does the LPV358DDUR support single-supply operation?
Yes, the LPV358DDUR supports true single-supply operation from 2.7 V to 5 V. Its input common-mode range extends to −0.2 V (below ground) and up to VCC+ − 0.8 V, and its rail-to-rail output swings within 3.5 mV of VCC+ and 90 mV of VCC− - enabling full-swing signal handling with GND as the negative rail. This is verified in the "Electrical Characteristics" tables for both 2.7 V and 5 V conditions.
Is the LPV358DDUR pin-compatible with standard SOIC-8 op-amps like the LM358?
No, the LPV358DDUR uses the VSSOP-8 (DDU) package with 0.5 mm pitch and 3.0 mm × 3.0 mm body size - it is not physically or electrically pin-compatible with SOIC-8 devices such as the LM358 or LMV358. The pinout matches the industry-standard dual op-amp configuration (OUT A, IN− A, IN+ A, V−, V+, IN+ B, IN− B, OUT B), but PCB layout requires dedicated VSSOP-8 footprints. Migration from SOIC-8 requires board redesign.
What is the typical input bias current of the LPV358DDUR at room temperature?
The typical input bias current of the LPV358DDUR is 2 nA at TA = 25°C and VCC = 5 V, as specified in the "5-V electrical characteristics" table of the SLOS433I datasheet. Over the full −40°C to +85°C range, the maximum input bias current is 60 nA - a key advantage for high-impedance sensor interfaces where leakage current would otherwise introduce significant error.
Can the LPV358DDUR drive a 1000 pF capacitive load without oscillation?
Yes, the LPV358DDUR is explicitly characterized for stability with capacitive loads up to 1000 pF, as stated in the "Features" section and confirmed in Figure 14 and Figure 15 of the SLOS433I datasheet. This eliminates the need for series isolation resistors when driving ADC input capacitors, sample-and-hold circuits, or long PCB traces - simplifying design and improving signal integrity in mixed-signal systems.
