Product details
Overview
LPV358IDRG4 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-designed for battery-powered sensor signal conditioning and portable medical instrumentation.
For engineers reviewing the LPV358IDRG4 datasheet, LPV358IDRG4 pinout, LPV358IDRG4 application, or LPV358IDRG4 equivalent, this page delivers verified electrical specs, SOIC-8 package details, real-world use cases in low-power analog front-ends, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The LPV358IDRG4 integrates two independent amplifiers in a single SOIC-8 package, each featuring rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ load) and input common-mode range extending to ground (VICR = −0.2 V to VCC+ − 0.8 V). It achieves stable operation with capacitive loads up to 1000 pF and exhibits no crossover distortion.
Its 152 kHz GBW and 0.1 V/μs slew rate support precision DC-coupled amplification and low-frequency active filtering. Input offset voltage is specified at 11 mV max over −40°C to 125°C, with CMRR ≥ 50 dB and PSRR ≥ 50 dB across the full supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-power, rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2372IDR | Higher supply current (20 μA/channel), wider VCC range (2.7–16 V), lower input offset (5 mV max) | Better suited for mixed-voltage systems requiring 12 V compatibility; less optimal for ultra-low-power designs | Select when higher supply voltage headroom or tighter offset spec is required, accepting 33% higher quiescent power |
| MCP6022-I/SN | Higher GBW (1 MHz), higher supply current (100 μA/channel), same SOIC-8 package | Targeted at higher-speed sensor interfaces (e.g., ultrasonic flow meters); not suitable for sub-100 μA battery budgets | Choose when bandwidth >500 kHz is mandatory and power budget allows ≥100 μA per channel |
Compared with TLV2372IDR and MCP6022-I/SN, the LPV358IDRG4 delivers the lowest power envelope for dual-channel rail-to-rail amplification at 152 kHz GBW, making it the optimal choice for energy-constrained, temperature-extended applications where speed is secondary to efficiency and thermal resilience.

FAQ
What is the maximum operating temperature specification for LPV358IDRG4?
The LPV358IDRG4 is characterized for continuous operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This rating is confirmed in the "recommended operating conditions" table of the SLOS433I datasheet, with electrical parameters guaranteed across this full range.
Does LPV358IDRG4 support rail-to-rail input operation?
No, LPV358IDRG4 does not support rail-to-rail input. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V, meaning it accepts inputs down to 0.2 V below ground but only up to 0.8 V below the positive rail. Input signals must remain within this window to maintain specified CMRR and offset performance.
What package type and lead finish does LPV358IDRG4 use?
LPV358IDRG4 uses an 8-pin SOIC (D) package with green RoHS-compliant finish (Pb-free, no Sb/Br), CU NIPDAU plating, and JEDEC MSL Level-1 moisture sensitivity rating-enabling unlimited floor life and standard reflow soldering without baking.
Can LPV358IDRG4 drive capacitive loads up to 1000 pF without instability?
Yes, the LPV358IDRG4 is explicitly characterized for stability with capacitive loads up to 1000 pF, as stated in the "Features" section and verified in Figure 14 and Figure 15 of the SLOS433I datasheet. No external isolation resistor is required for such loads, simplifying PCB layout in sensor interface designs.
How does the supply current of LPV358IDRG4 compare between 2.7 V and 5 V operation?
At 25°C, LPV358IDRG4 draws 15 μA per channel at 5 V and 12 μA per channel at 2.7 V (typical). The supply current increases slightly with temperature-up to 24 μA per channel at 85°C and 80 μA per channel at 125°C under 5 V operation-making it highly predictable for battery-life modeling across environments.
