Product details
Overview
LPV358DGKRG4 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, ±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 portable instrumentation.
For engineers reviewing the LPV358DGKRG4 datasheet, LPV358DGKRG4 pinout, LPV358DGKRG4 application, or LPV358DGKRG4 equivalent, key selection criteria include its guaranteed operation from −40°C to 125°C (I-grade), stable performance with 1000-pF capacitive loads, no crossover distortion, and compatibility with space-constrained designs using the 8-pin MSOP (DGK) package.
Technical Context
The LPV358DGKRG4 implements a complementary input stage enabling rail-to-rail input common-mode range down to −0.2 V and up to VCC+ − 0.8 V. Its output stage uses Class AB architecture to achieve true rail-to-rail swing while maintaining low quiescent current across temperature.
It is internally compensated for unity-gain stability and remains stable driving up to 1000 pF directly-eliminating need for external isolation resistors in capacitive-load scenarios such as ADC driver or filter stages. The device exhibits 71° phase margin at 2.7 V and 74° at 5 V with 22-pF load.
Key Specifications

| Supply Voltage Range | 2.7 V to 5 V - supports single-cell Li-ion and two-cell alkaline systems without LDO. |
| Quiescent Current (per channel) | 15 μA at 5 V - enables multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 152 kHz - sufficient for DC-coupled signal conditioning and anti-aliasing filters up to ~10 kHz. |
| Input Offset Voltage | 7 mV max (25°C), 11 mV max (−40°C to 125°C) - suitable for medium-accuracy industrial sensing. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ - maximizes dynamic range in low-voltage data acquisition. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows direct interfacing to ground-referenced sensors and DACs. |

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 |
|---|---|---|---|
| LMV358IDGKR | Higher supply current (80 μA per channel at 125°C), wider input offset (12 mV max over temp), same DGK package. | Targeted at cost-sensitive consumer electronics where extended temperature range is not required. | Select LMV358IDGKR only if 125°C operation is unnecessary and higher power budget exists. |
| TLV2372IDGKR | Lower supply current (10 μA per channel), lower input offset (3 mV typ), but reduced GBW (130 kHz) and narrower CMVR (to VCC− + 0.2 V). | Better suited for ultra-low-power sensor nodes with tighter offset requirements but less demanding bandwidth needs. | Choose TLV2372IDGKR when offset-critical DC amplification dominates over speed or rail-to-rail input capability. |
Compared with LMV358IDGKR, LPV358DGKRG4 provides superior thermal robustness and lower power at high temperature; versus TLV2372IDGKR, it trades minor current increase for guaranteed rail-to-rail input and higher bandwidth-making it optimal for dual-path, mixed-signal industrial interfaces.

The LPV358DGKRG4 is rated for operation from −40°C to +125°C, meeting the I-grade specification. This is confirmed in the "recommended operating conditions" table of the SLOS433I datasheet, where LPV358I variants-including LPV358DGKRG4-are explicitly characterized across this full industrial-plus-automotive range.
Does LPV358DGKRG4 support rail-to-rail input operation?
Yes, LPV358DGKRG4 supports rail-to-rail input operation with a common-mode input voltage range of −0.2 V to VCC+ − 0.8 V. This allows the inputs to accept signals down to 0.2 V below ground and up to 0.8 V below the positive rail-enabling direct interface with ground-referenced sources and unipolar DAC outputs without level-shifting circuitry.
What is the typical supply current of LPV358DGKRG4 at 5 V?
The typical supply current for LPV358DGKRG4 is 15 μA per channel at 5 V and 25°C, totaling 30 μA for both amplifiers. At −40°C to 125°C, the maximum supply current is 80 μA per channel, as specified in the 5-V electrical characteristics table under "ICC Supply current LPV358 (both amplifiers)".
Can LPV358DGKRG4 drive a 1000-pF capacitive load stably?
Yes, LPV358DGKRG4 is explicitly characterized for stable operation with up to 1000-pF capacitive loads, as stated in the "Features" section and verified in Figure 14 and Figure 15 of the SLOS433I datasheet. No external isolation resistor is required, simplifying design in ADC driver and filter applications.
What package type and dimensions does LPV358DGKRG4 use?
LPV358DGKRG4 uses the MSOP-8 (DGK) package: 3.0 mm × 3.0 mm × 1.0 mm body size with 0.65-mm lead pitch. Pin 1 location and footprint match JEDEC MO-187AA, and thermal resistance θJA is 172°C/W, as documented in the "absolute maximum ratings" table and TI's DGK package drawing.
