Product details
Overview
LPV358DR from Texas Instruments is a dual, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power (15 μA per amplifier at 5 V) operational amplifier optimized for portable and space-constrained applications. It delivers 152 kHz gain-bandwidth product, ±0.2 V to VCC+ − 0.8 V input common-mode range, 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 active filters.
For engineers reviewing the LPV358DR datasheet, LPV358DR pinout, LPV358DR application, or LPV358DR equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world use cases in low-power analog front-ends, and validated alternative parts with documented functional trade-offs for design-in decisions.
Technical Context
The LPV358DR implements a CMOS input stage with rail-to-rail output architecture, supporting operation down to 2.7 V while maintaining stable performance across −40°C to 85°C. Its input common-mode range extends 0.2 V below ground and 0.8 V below VCC, enabling single-supply sensing of bipolar signals without level-shifting circuitry.
It achieves 152 kHz unity-gain bandwidth with only 15 μA supply current per channel and remains stable driving capacitive loads up to 1000 pF - making it suitable for driving ADC inputs, filter stages, and low-noise sensor buffers where power efficiency and output headroom are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct connection to Li-ion, coin-cell, and 3.3 V logic rails without regulation. |
| Supply Current (per amp) | 15 μA typical at 5 V - enables multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 152 kHz - sufficient for anti-aliasing, DC-coupled instrumentation, and audio pre-amplification at ultra-low power. |
| Rail-to-Rail Output Swing | VOUT(HI) = VCC+ − 3.5 mV; VOUT(LO) = VCC− + 90 mV at 100-kΩ - maximizes dynamic range in single-supply systems. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows ground-referenced input signals and simplifies biasing in single-supply designs. |
| Input Offset Voltage | 7 mV typical (25°C, 5 V) - suitable for medium-accuracy signal conditioning where trimming is not required. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - robust handling in automated assembly and field environments. |
Pinout & Package
LPV358DR is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, 3.91-mm width, and 4.90-mm length - compatible with mainstream PCB assembly processes and legacy footprint libraries.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output; drives external load or next-stage input with rail-to-rail swing. |
| 2 | Inverting Input A | High-impedance node for feedback network connection in inverting configurations. |
| 3 | Non-Inverting Input A | High-impedance node for reference or sensor signal input in non-inverting configurations. |
| 4 | VCC− | Negative supply rail (typically GND); must be decoupled locally with 0.1-μF ceramic capacitor. |
| 5 | Non-Inverting Input B | Independent input for second amplifier; enables dual-channel signal processing in one IC. |
| 6 | Inverting Input B | Independent inverting input for amplifier B; supports separate feedback paths per channel. |
| 7 | Output B | Amplifier B output; electrically isolated from Output A - no crosstalk above 100 dB at 1 kHz. |
| 8 | VCC+ | Positive supply rail (2.7–5 V); shared by both amplifiers; requires local 0.1-μF bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Low quiescent current | 15 μA per amplifier at 5 V - reduces system-level power budget and thermal load in dense layouts. |
| Rail-to-rail output | Swings within 3.5 mV of VCC+ and 90 mV of VCC− at 100-kΩ - preserves full ADC input range without external level-shifting. |
| Stable with 1000-pF load | No external compensation required when driving ADC input capacitors or long traces - simplifies layout and reduces BOM count. |
| Extended temperature range | Specified from −40°C to +85°C - qualified for industrial and automotive cabin applications without derating. |
| No crossover distortion | CMOS output stage eliminates dead-zone artifacts in low-frequency AC signals - critical for precision sensor signal integrity. |

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 |
|---|---|---|---|
| LMV358DR | Higher supply current (80 μA per amp at 5 V), wider input range (−0.1 V to VCC−0.7 V), same SOIC-8 package. | Better offset voltage (3 mV typ) but 5× higher power draw - unsuitable for multi-year battery life requirements. | Select LMV358DR only when higher speed (1 MHz GBW) or lower offset is mandatory and power budget allows. |
| TLV2372IDR | Lower supply current (5.8 μA per amp), rail-to-rail I/O, but narrower supply range (2.7–16 V) and higher offset (3.5 mV typ). | Superior power efficiency but reduced output drive strength (10 mA vs 17 mA sourcing) - limits load capability in high-impedance ADC driver roles. | Choose TLV2372IDR when sub-10 μA per channel is critical and output loading is ≤10 kΩ. |
Compared with LMV358DR and TLV2372IDR, LPV358DR strikes a balanced trade-off: lower power than LMV358DR while offering stronger output drive and better noise performance than TLV2372IDR - making it optimal for dual-channel, battery-powered analog signal chains requiring reliability over extreme temperature ranges.

FAQ
What is the maximum operating temperature for LPV358DR?
The LPV358DR is characterized for operation from −40°C to +85°C. This specification is guaranteed per the datasheet under recommended conditions (VCC = 2.7 V to 5 V). It is not rated for the extended −40°C to +125°C range - that applies only to the LPV358IDR variant with "I" suffix.
Does LPV358DR support rail-to-rail input?
No, LPV358DR does not support rail-to-rail input. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V. While it accepts signals slightly below ground, it cannot handle inputs at VCC+ or VCC−. For true rail-to-rail input, consider alternatives like TLV2462 or OPA333.
Can LPV358DR drive a 1000-pF capacitive load without oscillation?
Yes, LPV358DR is explicitly characterized for stability with up to 1000-pF capacitive loads, as confirmed in the datasheet's Figure 14 and 15 frequency response plots. No external isolation resistor or compensation network is required when driving typical ADC input capacitances or long PCB traces.
What is the typical input offset voltage of LPV358DR at 25°C and 5 V supply?
The typical input offset voltage of LPV358DR is 7 mV at TA = 25°C and VCC = 5 V, as stated in the "5-V electrical characteristics" table on page 6 of the SLOS433I datasheet. Maximum offset is 10 mV over the full −40°C to +85°C range.
Is LPV358DR pin-compatible with LMV358DR?
Yes, LPV358DR and LMV358DR share identical SOIC-8 (D) package pinout and terminal functions. Both follow the standard dual op-amp configuration: Pin 1 (Out A), Pin 2 (In− A), Pin 3 (In+ A), Pin 4 (VCC−), Pin 5 (In+ B), Pin 6 (In− B), Pin 7 (Out B), Pin 8 (VCC+). However, electrical behavior differs significantly in supply current, bandwidth, and input range.
