Product details
Overview
LPV358DRG4 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 LPV358DRG4 datasheet, LPV358DRG4 pinout, LPV358DRG4 application, or LPV358DRG4 equivalent, key selection criteria include its ultra-low quiescent current, guaranteed operation from −40°C to 85°C, SOIC-8 package compatibility, and stable performance with 1000-pF capacitive loads-critical for space-constrained, energy-sensitive analog front-ends.
Technical Context
The LPV358DRG4 implements a complementary input stage enabling rail-to-rail input common-mode voltage range down to −0.2 V and up to VCC+ − 0.8 V. Its output stage uses Class AB architecture to achieve rail-to-rail swing while maintaining stability with capacitive loads up to 1000 pF without external compensation.
It operates across 2.7 V to 5 V supply rails and exhibits no crossover distortion, with input offset voltage ≤7 mV (typical) and input bias current ≤50 nA (typical) at 25°C. ESD protection exceeds JESD22-A114 (2 kV HBM), A115 (200 V MM), and C101 (1 kV CDM) standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-cell Li-ion and dual-cell alkaline battery systems without regulation. |
| Quiescent Current (per channel) | 15 μA at 5 V - enables multi-year operation in always-on sensor nodes and IoT endpoints. |
| Gain-Bandwidth Product | 152 kHz - sufficient for DC-coupled instrumentation, active filtering, and slow-sampling ADC drivers. |
| 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 sensing of signals referenced to ground or near-rail voltages. |
| Stable Capacitive Load | Up to 1000 pF - eliminates need for isolation resistors when driving ADC inputs or long PCB traces. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin ambient environments. |
Pinout & Package
LPV358DRG4 is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, 3.91-mm width, and JEDEC MS-012AC footprint-compatible with automated SMT assembly and legacy board layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives high-impedance loads directly; capable of sourcing/sinking ≥2 mA. |
| 2 | IN− A | Inverting input of amplifier A - accepts differential or single-ended feedback configurations. |
| 3 | IN+ A | Non-inverting input of amplifier A - supports ground-referenced sensor inputs due to extended VICR. |
| 4 | VCC− | Negative supply rail - connected to system ground in single-supply operation. |
| 5 | IN+ B | Non-inverting input of amplifier B - electrically isolated from amplifier A; enables dual-channel signal processing. |
| 6 | IN− B | Inverting input of amplifier B - supports independent gain-setting networks per channel. |
| 7 | OUT B | Amplifier B output - identical AC/DC performance to OUT A; no crosstalk degradation above 100 dB at 1 kHz. |
| 8 | VCC+ | Positive supply rail - accepts 2.7–5 V; internal biasing ensures rail-to-rail functionality across full range. |

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 channel), wider GBW (1 MHz), same SOIC-8 package. | Better suited for higher-speed signal paths but increases power budget by >5×. | Select LMV358DR only if bandwidth >500 kHz is required and power constraints allow. |
| TLV2372IDR | Lower quiescent current (5.5 μA), lower GBW (1.5 MHz), rail-to-rail I/O, same SOIC-8 footprint. | Superior power efficiency but reduced drive strength and higher input offset (3.5 mV max). | Choose TLV2372IDR for ultra-low-power applications where <10-μA/channel is mandatory and output loading is light. |
Compared with LMV358DR and TLV2372IDR, the LPV358DRG4 uniquely balances ultra-low power (15 μA), usable bandwidth (152 kHz), and robust output drive-making it optimal for cost-sensitive, battery-operated industrial and medical sensors where moderate speed and maximum runtime are co-prioritized.

FAQ
What is the maximum operating temperature range for the LPV358DRG4?
The LPV358DRG4 is specified for operation from −40°C to +85°C. This range is validated per the datasheet's recommended operating conditions and applies to all electrical characteristics unless otherwise noted. The device does not carry the "I" suffix (e.g., LPV358IDRG4), which denotes the extended −40°C to +125°C grade.
Does the LPV358DRG4 support rail-to-rail input operation?
No-the LPV358DRG4 features rail-to-rail *output* swing but has an input common-mode voltage range of −0.2 V to VCC+ − 0.8 V. While this extends below ground and nearly to the positive rail, it does not reach VCC+-so true rail-to-rail input operation is not supported. For full rail-to-rail input, consider TI's TLV2462 or similar alternatives.
Can the LPV358DRG4 drive a 1000-pF capacitive load without oscillation?
Yes-the LPV358DRG4 is explicitly characterized and guaranteed to remain stable with capacitive loads up to 1000 pF, as confirmed in the datasheet's Figure 14 and "Stable With Capacitive Load of 1000 pF" feature bullet. No external isolation resistor or compensation network is required under this condition.
What is the typical input offset voltage of the LPV358DRG4 at 5 V supply?
The typical input offset voltage of the LPV358DRG4 at 5 V supply and 25°C is 7 mV, with a maximum of 10 mV over the −40°C to +85°C temperature range. This value is specified in the "5-V electrical characteristics" table on page 6 of the SLOS433I datasheet.
Is the LPV358DRG4 pin-compatible with other dual op-amps in SOIC-8 packages?
The LPV358DRG4 follows the industry-standard dual op-amp pinout (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+), making it functionally and physically compatible with LMV358, TLC272, and TLV2372 in SOIC-8. However, electrical parameters-including supply current, bandwidth, and offset-differ significantly between these parts.
